Otolaryngology–Head and Neck Surgery

Pediatric hearing loss is an increasingly recognized problem with significant implications. Increasing our quantitative understanding of potentially modifiable environmental risk factors for hearing loss may form the foundation for prevention and screening programs.

To determine whether specific threshold exposure levels of personally modifiable risk factors for hearing loss have been defined, with the overarching goal of providing actionable guidance for the prevention of pediatric hearing loss.

A systematic review was performed. Computerized searches of PubMed, EMBASE, and the Cochrane Library were completed and supplemented with manual searches.

Inclusion/exclusion criteria were designed to determine specific threshold values of personally modifiable risk factors on hearing loss in the pediatric population. Searches and data extraction were performed by independent reviewers.

There were 38 criterion-meeting studies, including a total of 50,651 subjects. Threshold noise exposures significantly associated with hearing loss in youth included: (1) more than 4 hours per week or more than 5 years of personal headphone usage, (2) more than 4 visits per month to a discotheque, and (3) working on a mechanized farm. Quantified tobacco levels of concern included any level of in utero smoke exposure as well as secondhand exposure sufficient to elevate serum cotinine.

Specific thresholds analyses are limited. Future studies would ideally focus on stratifying risk according to clearly defined levels of exposure, in order to provide actionable guidance for children and families.

To determine if the current body of evidence describes specific threshold values of concern for modifiable societal-level risk factors for pediatric hearing loss, with the overarching goal of providing actionable guidance for the prevention and screening of audiological deficits in children.

Three related systematic reviews were performed. Computerized PubMed, Embase, and Cochrane Library searches were performed from inception through October 2013 and were supplemented with manual searches.

Inclusion/exclusion criteria were designed to determine specific threshold values of societal-level risk factors on hearing loss in the pediatric population. Searches and data extraction were performed by independent reviewers.

There were 20 criterion-meeting studies with 29,128 participants. Infants less than 2 standard deviations below standardized weight, length, or body mass index were at increased risk. Specific nutritional deficiencies related to iodine and thiamine may also increase risk, although data are limited and threshold values of concern have not been quantified. Blood lead levels above 10 µg/dL were significantly associated with pediatric sensorineural loss, and mixed findings were noted for other heavy metals. Hearing loss was also more prevalent among children of socioeconomically disadvantaged families, as measured by a poverty income ratio less than 0.3 to 1, higher deprivation category status, and head of household employment as a manual laborer.

Increasing our understanding of specific thresholds of risk associated with causative factors forms the foundation for preventive and targeted screening programs as well as future research endeavors.

To determine whether the research rotation experience affects the career path of otolaryngology residents.

Two web-based surveys were disseminated by the AAO-HNS; one to current and former resident trainees and the other to current residency program directors.

A web-based survey was disseminated to all AAO-HNS members classified as otolaryngology residents or residency graduates within the last 6 years, regarding their research rotation and its potential influence on their career path. A second web-based survey was delivered simultaneously to program directors to evaluate their perception of the need for research in a training program and their role in the rotation. Chi-square tests for independence as well as multivariate analyses were conducted to determine whether aspects of the resident research rotation related to career path.

The resident survey was completed by 350 respondents (25% response rate), and 39 program directors completed the second survey (37% response rate). Multiple factors were examined, including federal funding of faculty, mentorship, publications prior to residency, success of research project measured by publication or grant submission, and type of research. Multivariate analyses revealed that factors most predictive of academic career path were intellectual satisfaction and presence of a T32 training grant within the program (P < .05).

The composition and quality of the residency research rotation vary across institutions. Factors that enhance stronger intellectual satisfaction and the presence of T32 grant, which demonstrates an institution’s commitment to research training, may promote pursuit of a career in academia versus private practice.

To compare the different modalities for treatment of Zenker’s diverticulum and the associated clinical outcomes.

Case series with chart review.

Tertiary care hospital.

Between 1995 and 2011, 164 patients underwent surgery for Zenker’s diverticulum (stapler, n = 69; laser, n = 68; open, n = 27). Patient sociodemographics, medical comorbidities, pre- and postoperative subjective dysphagia and regurgitation score, complications, length of stay, time to oral intake, and recurrence were reviewed for each surgical modality.

No statistically significant difference in diverticulum prevalence was associated with age, gender, or treatment group. Mean length of hospital stay was not significantly different between the 3 groups (P = .14). A significant difference in time to oral intake was observed in the laser group compared with the other 2 groups (P = .012). No significant difference in recurrence (P = .21) or complication (P = .12) rates was identified between the 3 groups. Although all 3 groups demonstrated a significant decrease between preoperative and postoperative dysphagia and regurgitation scores, the degree of improvement was not significant when the 3 groups were compared.

There is no single “best” approach to Zenker’s diverticulum. The open, laser, and stapler methods are equally effective and have similar complication rates.

Our objective is to describe a novel operative technique for localization of parotid sialolithiasis, demonstrate the feasibility of the technique, and discuss its indications.

Prospective study.

Tertiary-level academic center.

Patients with symptomatic parotid sialolithiasis who had failed prior sialendoscopic extraction underwent ultrasound needle localization and open sialolithotomy. Data were prospectively collected. Independent variables included size of and location of sialoliths.

Eleven patients were treated using transcutaneous ultrasound-guided needle placement and injection of methylene blue prior to external sialolithotomy. Follow-up ranged from 6 to 12 months. Ten (91.9%) patients had stones within the proximal one-third of the ductal lumen, and 1 (9.1%) had stones present within both the proximal one-third and middle one-third of the ductal lumen. The average surgical time was 53 ± 10.8 minutes. The average sialolith length was 7.6 ± 2 mm. The average sialolith width was 6 ± 1.9 mm. All 11 (100%) cases were successful for stone retrieval. Ten (91%) patients had complete symptom resolution, and 1 (9.1%) patient had partial resolution of symptoms. No patients had major complications. Three (27.3%) patients had minor complications.

After failing a purely endoscopic approach, sialoliths of the parotid gland pose a problem for precise localization and treatment. Ultrasound has been demonstrated to be reliable for identifying sialoliths. We propose a novel technique and assert that ultrasound-guided needle localization is a reliable aid to effective external parotid sialolithotomy, especially for larger stones >4 mm that are not amenable to sialendoscopic retrieval.

(1) Confirm the positive value stream of office-based ultrasound using Lean Six Sigma; (2) demonstrate how ultrasound reduces time to diagnosis, costs, patient inconvenience and travel, exposure to ionizing radiation, intravenous contrast, and laboratory tests.

Case series with historical controls using chart review.

Tertiary Veterans Administration Hospital (university-affiliated).

Patients with a consult request or decision for ultrasound guided fine needle aspiration (USFNA) from 2006 to 2012. Process evaluation using Lean Six Sigma methodologies; years study conducted: 2006-2012; outcome measurements: type of diagnostic tests and imaging studies including CT scans with associated radiation exposure, time to preliminary and final cytopathologic diagnosis, episodes of patient travel.

Value stream mapping prior to and after implementing office-based ultrasound confirmed the time from consult request or decision for USFNA to completion of the USFNA was reduced from a range of 0 to 286 days requiring a maximum 17 steps to a range of 0 to 48 days, necessitating only a maximum of 9 steps. Office-based USFNA for evaluation of head and neck lesions reduced costs, time to diagnosis, risks and inconvenience to patients, radiation exposure, unnecessary laboratory, and patient complaints while increasing staff satisfaction. In addition, office-based ultrasound also changed the clinical management of specific patients.

Lean Six Sigma reduces waste and optimizes quality and accuracy in manufacturing. This is the first known application of Lean Six Sigma to office-based USFNA in the evaluation of head and neck lesions. The literature supports the value of office-based ultrasound to patients and health care systems.

This study aimed to determine the feasibility of using probe-based confocal laser endomicroscopy (pCLE) in the diagnostic differentiation of non-neoplastic lesions from precancerous and cancerous lesions of head and neck patients.

Diagnostic test evaluation.

Louisiana State University Health Shreveport.

Intravenous injection of fluorescein was given to patients with precancerous and cancerous head and neck lesions (n = 21) followed by the use of a 1.8-mm GastroFlex probe in the oral cavity with subsequent biopsies of selected areas. Probe-based confocal laser endomicroscopy images were compared to histologic evaluation of visualized sites using sensitivity, specificity, negative predictive value (NPV), and positive predictive value (PPV).

The dorsal surface of the tongue was not well visualized. The remaining nonkeratinized subsites, including the buccal mucosa, floor of mouth, and ventral tongue, were well visualized. Diagnoses based on pCLE images correlated well with the gold standard diagnoses based on tissue histology. The overall sensitivity for diagnosis of dysplasia versus nondysplasia was 80.0% (95% confidence interval [CI], 62.0-98.0), specificity and PPV were 100%, and the NPV was 80.0% (95% CI, 60.0-100.0). The overall specificity, sensitivity, PPV, and NPV for pCLE diagnosis of carcinoma versus nondysplasia were 100%. The overall sensitivity for diagnosis of carcinoma versus dysplasia was 85.7% (95% CI, 73.0-99.0), specificity and PPV were 100%, and the NPV was 80.0% (95% CI, 60.0-100.0).

The pCLE is a promising method for differentiating between nondysplastic, precancerous, and cancerous lesions of the head and neck.

The University HealthSystem Consortium (UHC) database collects discharge information on patients treated at academic health centers throughout the United States. We sought to use this database to identify outcome predictors for patients undergoing total laryngectomy. A secondary end point was to assess the validity of the UHC’s predictive risk mortality model in this cohort of patients.

Retrospective review.

Academic medical centers (tertiary referral centers) and their affiliate hospitals in the United States.

Using the UHC discharge database, we retrieved and analyzed data for 4648 patients undergoing total laryngectomy who were discharged between October 2007 and January 2011 from all of the member institutions. Demographics, comorbidities, institutional data, and outcomes were retrieved.

The length of stay and overall costs were significantly higher among female patients (P < .0001), while age was a predictor of intensive care unit stay (P = .014). The overall complication rate was higher among Asians (P = .019) and in patients with anemia and diabetes compared with other comorbidities. The average institutional case load was 1.92 cases/mo; we found an inverse correlation (R = −0.47) between the institutional case load and length of stay (P < .0001). The UHC admit mortality risk estimator was found to be an accurate predictor not only of mortality (P < .0002) but also of intensive care unit admission and complication rate (P < .0001).

This study provides an overview of laryngectomy outcomes in a contemporary cohort of patients treated at academic health centers. UHC admit mortality risk is an excellent outcome predictor and a valuable tool for risk stratification in these patients.

To determine the benefit to postoperative facial function of intraoperative facial nerve monitoring (IFNM) during recurrent pleomorphic adenoma (RPA) parotid surgery.

Cohort study with planned data collection.

Chinese PLA General Hospital.

Fifty-eight RPA parotidectomies were performed between 2004 and 2012. Recurrence was confirmed by histopathologic examination. None of the patients had preoperative facial palsy. Electromyography-based IFNM was used in 28 patients; 30 patients were unmonitored. The durations of surgery and the severity of postoperative facial nerve palsy were compared between the 2 groups.

There were no significant differences between the 2 groups in the incidence of immediate or permanent facial paralysis after RPA parotidectomy (P = .95 and P = .36, respectively). However, the differences in the average duration of surgery and the severity of postoperative facial nerve palsy after total parotidectomy or wide resection were significant (P < .01 and P = .01, respectively). In contrast, these differences were not significant after superficial parotidectomies (P = .43 and P = .49, respectively). The average recovery time of temporary facial nerve paralysis was significantly shorter in the monitored group compared with the unmonitored group, independent of surgical technique (P < .01).

The use of IFNM during total or wide resection RPA parotidectomy reduced the duration of surgery and the incidence of postoperative facial paralysis and enhanced recovery. However, there was little impact on facial nerve outcomes when IFNM was used during superficial RPA parotidectomy.

To demonstrate the feasibility of detecting and quantifying extracellular signal-related kinase (ERK) phosphorylation status using nanoimmunoassay (NIA).

Analyses using Cal27, SCC25, and OSC19 head and neck squamous carcinoma cell lines in vitro and in a murine xenograft model.

NIA and immunoblot were performed on whole-cell lysates, tumor lysates, and fine-needle aspirate biopsies to detect ERK phosphorylation states.

Using NIA, all 6 isoforms of ERK1/2, including nonphosphorylated, monophosphorylated, and diphosphorylated species, could be reliably detected, distinguished, and quantified in a single assay using a single antibody. In vitro treatment of Cal27 cells with the epidermal growth factor receptor inhibitor gefitinib abolished phospho-ERK detection by immunoblot but resulted in residual detectable species by NIA. Residual phospho-ERK in gefitinib-treated cells could be further reduced by the addition of the insulin-like growth factor 1 receptor inhibitor OSI-906; this correlated with an additional decrease in proliferation over gefitinib alone. In a pilot study of 4 murine xenograft tumors, NIA performed on tumor lysates and fine-needle aspirate biopsies demonstrated altered ERK profiles after 2 days of gefitinib treatment compared with untreated mice.

NIA offers a novel approach to quantitating the activation state of signaling molecules such as ERK in nanoscale in vitro and in vivo samples across a wide dynamic range. As such, it has potential to provide molecular diagnostic information before, during, and after treatment using a minimally invasive technique. Further study is warranted to determine its utility in assessing signaling proteins as biomolecular outcome predictors in clinical trials.

To explore the effects of 30 Gy of ⁶⁰Co γ-rays on apoptosis and reactive oxygen species (ROS) levels in minipig parotid cells as a possible mechanism for radiation-induced parotid injury.

Experimental study.

Department of Radiotherapy, First Affiliated Hospital, Guangxi Medical University, Nanning, China.

Forty male minipigs were divided into control and irradiated groups. Terminal deoxynucleotidyl transferase deoxyuridine triphosphate nick-end labeling was used for detecting apoptosis in the parotid cells, immunohistochemistry, and western blots were used to test expression of the B-cell lymphoma 2 (Bcl-2) and BCL2-associated X (Bax) proteins, and reverse transcription polymerase chain reaction was used to analyze the expression of Bcl-2, Bax, p53, and caspase-3 messenger ribonucleic acid. An enzyme-linked immunosorbent assay was used to detect ROS levels in the parotid tissue.

At each time point, the apoptotic rates in the irradiated group were higher than those in the control group. Furthermore, the ROS and expression levels of Bax, p53, and caspase-3 messenger ribonucleic acid and proteins gradually increased and were higher than those in the control group. Conversely, the expression of Bcl-2 was decreased in the irradiated group (P < .05).

Ionizing radiation induces the production of ROS and promotes changes in the expression of several apoptotic proteins, which increases apoptosis and likely contributes to the mechanism of radiation-induced parotid injury.

Minimally invasive, transnasal endoscopic approaches to the larynx have been utilized but are limited by the precision and accuracy afforded to the surgeon. The objective of this study is to analyze the feasibility of a rapidly deployable telerobotic system for enabling transnasal microsurgery of the larynx and upper airways, specifically injection laryngoplasty.

This is a feasibility study.

This study was conducted at a laboratory in the Department of Mechanical Engineering at Vanderbilt University.

A feasibility study was conducted in which a telerobotic system was transnasally inserted in both a human intubation trainer mannequin and a cadaver. A flexible needle was passed through an instrumentation port and targeted specific areas of the vocal folds of our models to simulate injection laryngoplasty. The experiments were recorded with both still and video photography. Average forces exerted on surrounding tissue and times of deployment were measured.

Our robot was able to expeditiously gain access to the glottis with an average manual insertion time of 5.87 seconds while exerting minimal forces on the surrounding tissues with an average force of 4.45 Newtons. The onboard fiberoptic endoscope conveyed images of adequate quality for the completion of a simulated injection medialization laryngoplasty. The experiment was successfully completed in both mannequin and cadaveric models.

This telerobotic system proved to be capable of being rapidly deployed to the upper airways while exerting minimal forces to the surrounding structures and successfully simulated injection medialization laryngoplasty.

Malignant otitis externa (MOE) is an invasive infection of the temporal bone that is classically caused by Pseudomonas aeruginosa. Increasingly, however, nonpseudomonal cases are being reported. The goal of this study was to evaluate and compare the clinical presentation and outcomes of cases of MOE caused by Pseudomonas versus non-Pseudomonas organisms.

Retrospective case series with chart review.

Tertiary care institution.

Adult patients with diagnoses of MOE between 1995 and 2012 were identified. Charts were reviewed for history, clinical presentation, laboratory data, treatment, and outcomes.

Twenty patients diagnosed with and treated for MOE at the University of Pittsburgh Medical Center between 1995 and 2012 were identified. Nine patients (45%) had cultures that grew P aeruginosa. Three patients (15%) had cultures that grew methicillin-resistant Staphylococcus aureus (MRSA). Signs and symptoms at presentation were similar across groups. However, all of the patients with Pseudomonas had diabetes, compared with 33% of MRSA-infected patients (P = .046) and 55% of all non-Pseudomonas-infected patients (P = .04). Patients infected with MRSA were treated for an average total of 4.7 more weeks of antibiotic therapy than Pseudomonas-infected patients (P = .10). Overall, patients with non-Pseudomonas infections were treated for a total of 2.4 more weeks than Pseudomonas-infected patients (P = .25).

A high index of suspicion for nonpseudomonal organisms should be maintained in patients with signs and symptoms of MOE, especially in those without diabetes. MRSA is an increasingly implicated organism in MOE.

Describe the relationship between cochleovestibular schwannoma (CVS) volume, audiovestibular characteristics, and magnetic resonance imaging (MRI) findings in patients with neurofibromatosis type 2 (NF2).

Subgroup analysis of NF2 prospective natural history study from 2008 to 2011.

Quaternary medical research institute.

NF2 patients with small treatment-naive CVSs (volume <1000 mm³) by ear; N = 49 ears (32 patients). Cross-sectional analysis of the following parameters was performed: tumor size, auditory brainstem response (ABR), 4-frequency pure-tone average (4f-PTA; 0.5, 1, 2, and 4KHz), cervical vestibular evoked myogenic potential (cVEMP), caloric testing, 240° velocity step test (VST), and MRI findings.

For all physiologic measures but the 4f-PTA, larger tumors correlated with abnormal responses (P < .05). For abnormal ABR, mean tumor volume was 405 vs 151 mm³ (P = .0007) for normal ABR. Similarly, larger tumors correlated with weak caloric responses (mean 521 vs 165 mm³; P = .0007) and weak cVEMP (mean 357 vs 192 mm³; P = .0262). Tumor volume was not significantly correlated with 4f-PTA. Elevated intralabyrinthine protein on MRI fluid-attenuated inversion recovery sequences was correlated with larger tumor volume (mean 333 vs 55 mm³; P = .001) and abnormal ABR and 4f-PTA (P < .05) but did not correlate with cVEMP, VST, or caloric responses.

In our cohort, ABR, caloric response, cVEMP, and elevated intralabyrinthine protein correlated with tumor volume, but 4f-PTA did not. Abnormal ABR and 4f-PTA correlated with elevated intralabyrinthine protein. These findings may provide insight on the effect of small CVS on the inner ear and cochleovestibular nerves, which may aid in their optimal management.

Studies of balloon Eustachian tuboplasty (BET) have shown encouraging results in small series with short follow-ups. Our pilot study suggested that patients with protracted otitis media with effusion (OME) or atelectasis of the tympanic membrane (TM) could benefit from BET.

A prospective study where subjects act as their own controls. Patients from the pilot study and additional cases were enrolled in this cohort with long-term follow-up.

Regional Academic Center.

Out of 80 patients who underwent BET, 41 consecutive Eustachian tube (ET) operations were included. Subjects’ inclusion criteria were OME and/or TM atelectasis, type B or C tympanograms, and inability to inflate their middle ears by Valsalva maneuver. All patients had longstanding ET dysfunction relieved only by repeated tympanostomies. Outcomes included ability to perform a Valsalva maneuver, audiometry, tympanometry, videoendoscopy of the ET with mucosal inflammation rating scores, and otomicroscopy.

All cases were dilated successfully, without significant complications. Mean follow-up was 2.5 years (range, 1.5-4.2 years). Eighty percent (33/41) could do a Valsalva maneuver postoperatively; none of these ears required new tympanostomy tubes and subjective symptoms were relieved. Tympanometry results showed overall improvement. Nine patients had persistent perforations and 3 declined removal of the tube. Subjective symptoms were not relieved for 10% (4/41).

The results show that BET can effectively improve ET function in ears with OME or atelectasis. The procedure is well tolerated and without significant complications. The follow-up continues and we are investigating possible reasons for failures.

To determine if some common screening tests predict scores on detailed, objective diagnostic tests of the vestibular system.

Sixty patients with vestibular disorders were compared with 60 asymptomatic controls.

Vestibular diagnostic laboratory, tertiary care center.

Subjects were screened with head impulse tests, Fukuda stepping tests while walking and marching in place, and tandem walking tests with eyes open and closed. All subjects underwent bithermal caloric tests and Dix-Hallpike maneuvers; patients underwent low-frequency sinusoidal tests of the vestibulo-ocular reflex in darkness and cervical vestibular evoked myogenic potentials.

On tandem walking tests, patients differed significantly from controls, but receiver operating characteristic scores were < 0.80. On Fukuda tests, patients turned significantly more than controls for walking but not marching, but receiver operating characteristic values were considerably less than 0.80. On head impulse tests, patients with bithermal caloric weakness (≥20% and <60%) did not differ from controls, but patients with severe bithermal caloric weakness (≥60%) differed significantly from controls. Receiver operating characteristic values were >0.80 only for subjects with severe bithermal caloric weakness and were highest, at 0.88, for subjects with severe weakness and age ≥ 60 years.

The Fukuda test is a poor screening test because it does not correlate well with objective test findings. Tandem walking is best used for screening older patients for vestibular disorders. Positive findings on a head impulse test are probably consistent with severe peripheral vestibular impairment and may be most useful in older patients. In younger patients with vertigo, negative results on head impulse tests may not be informative.

(1) To determine the association between socioeconomic status (SES), race/ethnicity, and other demographic risk factors in surgically managed otitis media within a model of universal health care. 2) To determine quality of life (QOL) outcomes of surgically managed otitis media in this model.

Tertiary academic medical center.

Prospective cohort study.

A prospective study was conducted between June 2011 and December 2012 with dependent children of military families. TRICARE provides equal access to care among all beneficiaries regardless of a wide range of annual incomes. Caretakers of children scheduled for bilateral myringotomy and tympanostomy tube (BMT) placement were administered a demographic survey, as well as OM-6 QOL instrument preoperatively and 6 weeks postoperatively. A control group who did not undergo BMT was also administered both the survey and OM-6 for comparison.

Two hundred forty patients were enrolled (120 surgical patients and 120 controls). Logistic regression demonstrated age younger than 6 years old (P < .001), day care attendance (P < .001), and non-Hispanic Caucasian race (P = .022) to be associated with surgery. Surgical QOL outcomes demonstrated a significant improvement in otitis media-6 (OM-6) scores after surgical management from 3.00 (95% confidence interval [CI], 2.79-3.20) to 1.35 (95% CI, 1.22-1.47).

In a universal health care model serving more than 2 million children, previously reported proxies of low SES as well as minority race/ethnicity were not associated with surgically managed otitis media contrary to reported literature. Caucasian race, young age, and day care attendance were associated with surgery. Surgery improved QOL outcomes 6 weeks postoperatively.

Otitis media in children may have a considerable impact on caregiver quality of life. The disease-specific Caregiver Impact Questionnaire is designed to assess caregiver quality of life in relation to child otitis media. Assessment of the psychometric properties of this instrument is limited. This study assesses the psychometric properties of this instrument including validity, reproducibility, responsiveness, and interpretability.

Longitudinal validation study.

Secondary care units.

Analyses were based on data from 435 families. Validity was assessed using confirmatory factor analysis, internal consistency, and hypothesis testing. Test–retest reliability and measures of smallest detectable change were investigated in the assessment of reproducibility. Responsiveness was investigated by means of hypothesis testing and receiver operating characteristic analysis. An anchor-based distribution method was applied for determining minimal important change as perceived by the respondent.

Factor analysis confirmed the hypothesized 1-factor structure with an acceptable fit. Cronbach’s alpha was .90. In the analysis of construct validity, 88.9% of the hypothesized correlations were correctly predicted. Intraclass correlation coefficient was 0.87 and smallest detectable change corresponded to approximately one-fourth of the scale. Responsiveness was found to be good and a change score of 13.8 represented minimal important change.

The modified Danish version of the Caregiver Impact Questionnaire is a valid and reproducible measurement tool that is also sensitive to measuring change in the current setting. A change score representing minimal important change as perceived by the respondent is proposed. Results of this study support the use of this instrument.

Adenotonsillectomy (T&A) is the first line therapy for pediatric obstructive sleep apnea (OSA); however, inconsistency between objective and subjective outcomes perplexes physicians. This study investigates changes of objective and subjective outcomes in children with OSA after T&A, in particular, to elucidate correlations and discrepancies between these 2 measures.

Case series with record review.

Tertiary referral medical center.

Symptomatic children with polysomnographic diagnosis of OSA (apnea-hypopnea index [AHI] > 1) were included. All children underwent T&A to treat OSA, along with completely objective (polysomnography) and subjective (Obstructive Sleep Apnea 18-Item Quality-of-Life Questionnaire [OSA-18]) measures before and 3 months after surgery.

One hundred nineteen children were included (mean age, 6.9 ± 3.3 years; 76% boys). Adenotonsillectomy significantly reduced AHI from 15.4 ± 21.2 per hour to 1.6 ± 2.5 per hour (P < .001). The OSA-18 scores were significantly improved after surgery (P < .001). A weak but statistically significant positive correlation was found between AHI and OSA-18 scores preoperatively (ρ = 0.22, P = .016) but not postoperatively (ρ = 0.04, P = .677). Among those cases with residual OSA after surgery, only 6% (3/54) had a residual effect on quality of life (OSA-18 score > 60).

Adenotonsillectomy improves both objective and subjective outcomes. After surgery, quality of life significantly improved subjectively, despite an incomplete resolution of OSA objectively, leading to a better correlation between objective and subjective measures before as opposed to after surgery. Discrepancy between the 2 measures warrants an evaluation of a child both objectively and subjectively when treating OSA.

Considerable advances in endoscopic technique and experience have allowed an increasing number of patients with complex frontal sinus disease to be treated with endoscopic surgery. The objective of the current study was to evaluate management strategies and outcomes regarding treatment of lateral frontal sinus disease.

Prospective case series.

Academic tertiary medical center.

Prospectively collected data concerning frontal sinus pathology located lateral to the plane of the lamina papyracea (lateral disease) were reviewed. Data were collected regarding demographics, etiology, surgical technique, revision rate, anatomic considerations, and clinical follow-up. Only patients with at least 24 weeks of clinical follow-up and pathology who required removal and dissection in this region were included in the study.

Over 5 years, 156 patients (mean age, 47.9 years; range, 14-84 years) with 183 lateral frontal sinus pathologies and an average clinical follow up of 76 weeks (range, 24-237 weeks) were evaluated. Endoscopic or open surgery was attempted in 84 patients (54%) prior to intervention at our institution. Primary pathologies included inflammatory/obstructive diseases (n = 119), skull base defects (n = 33), and tumors (n = 31). Initial interventions included endoscopic (Draf IIA, n = 76; Draf IIB, n = 52; Draf III, n = 23), extended (IIA + trephine, n = 1; III + trephine, n = 2; III + osteoplastic flap, n = 2), and open (osteoplastic flap, n = 3; Reidel, n = 1; cranialization, n = 1) procedures. Seven patients (4%) required a subsequent revision procedure.

The vast majority of lateral frontal sinus pathology was managed using endoscopic techniques with excellent outcomes and a low revision rate in the current study.

The 6-question EuroQol 5-Dimension Health Assessment (EQ-5D) is a widely used, simple instrument that monitors general health-related quality of life (HRQoL) in chronic disease. It has not previously been applied to US patients undergoing endoscopic sinus surgery (ESS).

Prospective cohort study.

Academic Medical Center.

The study population consisted of 267 patients with chronic rhinosinusitis (CRS) who completed 2 disease-specific instruments—the Chronic Sinusitis Survey (CSS) and the Sinonasal Outcomes Test-22 (SNOT-22)—and 1 general health-related quality-of-life instrument—the EQ-5D—before and after ESS for CRS. Baseline scores were compared to those collected 3 and 12 months after surgery and to the general US population.

Surveys were completed at all time points by 186 patients, for a response rate of 69.7%. Patients with CRS, when compared to the US population, reported more problems in the domains of pain/discomfort (73.1% vs 40.8%, P < .01), anxiety/depression (50.5% vs 26.4%, P < .01), and usual activities (30.6% vs 15.0%, P < .01). One year following ESS, there was a significant decrease in patients who reported problems with pain/discomfort (54.3%, P < .001), anxiety/depression (30.6%, P < .001), and usual activities (21.5%, P < .01). After surgery, CRS anxiety/depression scores were no different from those of the US general population. Chronic Sinusitis Survey and SNOT-22 scores demonstrated similar postoperative improvements.

The EQ-5D assessment provides meaningful general health outcomes data with low patient burden. Application of this instrument demonstrated long-term improvement in the quality of life of patients who undergo sinus surgery.

To evaluate the impact of combined nasal surgery and endoscopic sinus surgery on the objective measurements of obstructive sleep apnea (OSA) and sleep architecture by comparing polysomnographic data before and after combined surgery in patients with OSA.

Case series with chart review.

A single clinical site.

Patients with OSA and chronic rhinosinusitis who underwent combined nasal surgery and endoscopic sinus surgery and preoperative and postoperative polysomnography were identified. Patient charts were reviewed and preoperative and postoperative body mass index, apnea-hypopnea index (AHI), mean and minimum oxygen saturation, sleep efficiency, and sleep staging were compared.

Fifty-six patients were included in our study. Patients were divided into 3 groups on the basis of the severity of OSA: those with mild OSA (n = 9), those with moderate OSA (n = 23), and those with severe OSA (n = 24). After combined nasal and sinus surgery, the mean AHI significantly decreased from 33.5 ± 22.0 to 29.4 ± 20.8 (P = .009) in our overall population. Specifically, AHI improved significantly in patients with moderate OSA (from 22.3 ± 4.8 to 20.7 ± 8.2, P = .023) and severe OSA (from 52.3 ± 21.4 to 43.6 ± 23.9, P = .034), while patients with mild OSA did not have significant changes in AHI. Successful surgical procedures were achieved in only 2 of 56 patients.

Although combined nasal and sinus surgery may slightly improve AHI in a certain group of patients, it does not cure OSA or have a significant clinical impact.

The aim of this study is to report our new endoscopic technique for the repair of nasal septal perforations, called the “slide and patch” technique because it combines a mucoperiosteal free graft of the inferior turbinate with a mucosal rotational or advancement flap from the nasal septum.

Twenty-two patients with symptomatic septal nasal perforation of various sizes underwent our method of repair.

At the last follow-up, 21 (95.4%) perforations were closed. There was a partial closure in only 1 patient with a large perforation (3.5 cm in diameter). After surgery, 19 (86.3%) patients were asymptomatic, 2 (9%) showed persistence of crusting, and 1 (4.5%) showed the appearance of nasal obstruction 1 month postoperatively.

The method described herein has shown to be effective in nasal septal perforation repair and in nasal symptoms relief with the advantage of not requiring grafts from outside the nose.
