Otolaryngology–Head and Neck Surgery

Wide variation exists regarding reported outcomes after endoscopic sinus surgery (ESS) for chronic rhinosinusitis with nasal polyps (CRSwNP). This study seeks to combine data across studies to generate a summary measure and explore factors that might lead to variation.

OVID Medline, Scopus, EbscoHost, Database of Abstracts and Reviews of Effects, Health Technology Assessment, and National Health Service Economic Evaluation Database.

A search was performed following the PRISMA guidelines. Two independent researchers conducted a search using the mentioned data sources. Studies published before August 29, 2016, that involved ESS to treat CRSwNP were included. Mean changes in Sinonasal Outcome Test–22 (SNOT-22) scores were determined through metaregression of the following independent variables: publication year, sex, age, allergy status, asthma, tobacco use, prior surgery, follow-up length, and preoperative SNOT-22.

Fifteen articles with 3048 patients treated with ESS met inclusion criteria. Pooled analyses of SNOT-22 scores revealed a mean change of 23.0 points (95% CI, 20.2-25.8; P < .001). A metaregression of patient factor effects on the mean change of SNOT-22 scores demonstrated that age (r = 0.71, P = .01), asthma (r = 0.21, P = .01), prior ESS (r = 0.29, P = .01), and preoperative SNOT-22 score (r = 0.4, P < .01) correlated with greater improvement in SNOT-22 scores. Tobacco use (r = −0.91, P = .01) and longer lengths of follow-up (r = −0.45, P < .01) were associated with less improvement in SNOT-22 scores.

Quality-of-life outcomes are significantly improved after ESS among patients with CRSwNP. Patient-specific factors may affect the degree of SNOT-22 change after surgery.

To evaluate the recent developments in optical coherence tomography (OCT) for tympanic membrane (TM) and middle ear (ME) imaging and to identify what further development is required for the technology to be integrated into common clinical use.

PubMed, Embase, Google Scholar, Scopus, and Web of Science.

A comprehensive literature search was performed for English language articles published from January 1966 to January 2018 with the keywords “tympanic membrane or middle ear,”“optical coherence tomography,” and “imaging.”

Conventional imaging techniques cannot adequately resolve the microscale features of TM and ME, sometimes necessitating diagnostic exploratory surgery in challenging otologic pathology. As a high-resolution noninvasive imaging technique, OCT offers promise as a diagnostic aid for otologic conditions, such as otitis media, cholesteatoma, and conductive hearing loss. Using OCT vibrometry to image the nanoscale vibrations of the TM and ME as they conduct acoustic waves may detect the location of ossicular chain dysfunction and differentiate between stapes fixation and incus-stapes discontinuity. The capacity of OCT to image depth and thickness at high resolution allows 3-dimensional volumetric reconstruction of the ME and has potential use for reconstructive tympanoplasty planning and the follow-up of ossicular prostheses.

To achieve common clinical use beyond these initial discoveries, future in vivo imaging devices must feature low-cost probe or endoscopic designs and faster imaging speeds and demonstrate superior diagnostic utility to computed tomography and magnetic resonance imaging. While such technology has been available for OCT, its translation requires focused development through a close collaboration between engineers and clinicians.

To examine the association of industry payments for brand-name intranasal corticosteroids with prescribing patterns.

Cross-sectional retrospective analysis.

Nationwide.

We identified physicians prescribing intranasal corticosteroids to Medicare beneficiaries 2014-2015 and physicians receiving payment for the brand-name intranasal corticosteroids Dymista and Nasonex. Prescription and payment data were linked by physician, and we compared the proportion of prescriptions written for brand-name intranasal corticosteroids in industry-compensated vs non-industry-compensated physicians. We associated the number and dollar amount of industry payments with the relative frequency of brand-name prescriptions.

In total, 164,587 physicians prescribing intranasal corticosteroids were identified, including 7937 (5%) otolaryngologists; 10,800 and 3886 physicians received industry compensation for Dymista and Nasonex, respectively. Physicians receiving industry payment for Dymista prescribed more Dymista as a proportion of total intranasal corticosteroid prescriptions than noncompensated physicians (3.1% [SD = 9.6%] vs 0.2% [SD = 2.5%], respectively, P < .001). Similar trends were seen for Nasonex (12.0% [SD = 16.8%] vs 4.8% [SD = 13.6%], P < .001). The number and dollar amount of payment were significantly correlated to the relative frequency of Dymista (ρ = 0.26, P < .001 and ρ = 0.20, P < .001, respectively) and Nasonex prescriptions (ρ = 0.09, P < .001 and ρ = 0.15, P < .001, respectively). For Dymista, this association was stronger in otolaryngologists than general practitioners (P < .001). There was a stronger correlation between the percentage of prescriptions and the number and dollar amount of payments for Dymista than for Nasonex (P = .014 and P < .001).

Industry compensation for brand-name intranasal corticosteroids is significantly associated with prescribing patterns. The magnitude of association may depend on physician specialty and the drug’s time on the market.

To assess the value of ultrasound, if indicated, supplemented by sialendoscopy, in the diagnosis of sialolithiasis.

Retrospective study.

Referring center for salivary gland diseases.

All patients who presented with a suspected diagnosis of obstructive sialopathy between January 2011 and April 2017 and had not undergone any treatment were retrospectively evaluated. A total of 2052 patients and 2277 glands were included in the study. Ultrasound examinations were carried out initially and followed by sialendoscopy in all cases. Direct demonstration of sialothiasis by sialendoscopy, transoral ductal surgery, and discharge of concrements/observation of fragments during sialendoscopy after extracorporeal shock-wave lithotripsy were regarded as definitive evidence of sialolithiasis.

Ultrasound had an accuracy, sensitivity, specificity, positive predictive value, and negative predictive value of 94.77%, 94.91%, 94.57%, 96.14%, and 92.89%, respectively, for the diagnosis of sialolithiasis. All false-positive findings were correctly diagnosed, and in all false-negative findings, stones/fragments were visualized by sialendoscopy. Over 95% of the false-negative findings in major salivary glands (64/67) had visible ductal dilation in sonography, and in 73.1%, the stones not detected on ultrasound were located in the distal part of the duct, which is easily accessible with the sialendoscope.

This study shows that sialolithiasis can be diagnosed using ultrasonography with a high degree of certainty. If supplemented by sialendoscopy, the correct diagnosis could be established in virtually all cases of sialolithiasis. Ultrasound supplemented by sialendoscopy has the potential to serve as an alternative diagnostic standard in the future.

We evaluated the ability of the American Joint Committee on Cancer (AJCC) seventh edition staging system to prognosticate the overall survival of patients with human papillomavirus (HPV)–positive laryngeal squamous cell carcinoma.

Retrospective analysis.

National Cancer Database.

Patients diagnosed with laryngeal squamous cell carcinoma who were treated with curative intent were identified in the National Cancer Database. Multivariate analysis was utilized to determine factors correlated with overall survival in the HPV-negative and HPV-positive cohorts. Unadjusted and propensity score–weighted Kaplan-Meier estimation was used to determine overall survival of HPV-negative and HPV-positive patients across AJCC stage groupings.

We identified 3238 patients with laryngeal squamous cell carcinoma, of which 2812 were HPV negative and 426 were HPV positive. Overall survival adjusted for age, sex, and comorbidity status confirmed significant differences among all consecutive stage groupings (I vs II, P < .001; II vs III, P < .05; III vs IVA, P < .001; IVA vs IVB, P < .05) in the HPV-negative cohort, whereas only stages IVAs and IVB (P < .01) exhibited a significant difference in overall survival for HPV-positive patients.

The current AJCC staging system does not accurately distinguish risk of mortality for patients with HPV-positive disease. These data support the consideration of HPV status in estimating prognosis as well as clinical trial design and clinical decision making for patients with laryngeal squamous cell carcinoma.

To recognize the utility of the surgical Apgar score (SAS) in a noncutaneous head and neck squamous cell carcinoma (HNSCC) population.

Retrospective case series with chart review.

Academic tertiary medical center.

Patients (n = 563) undergoing noncutaneous HNSCC resection between April 2012 and March 2015 were included. Demographics, medical history, intraoperative data, and postoperative hospital summaries were collected. SASs were calculated following the published schema. The primary outcome was 30-day postoperative morbidity. A 2-sample t test, analysis of variance, and χ² (or Fisher exact) test were used for statistical comparisons. A multivariable logistic regression analysis was conducted to identify independent predictors of 30-day morbidity.

Mean SAS was 6.2 ± 1.5. SAS groups did not differ in age, sex, or race. Sixty-five patients (11.6%) had a SAS between 0 and 4, with 40 incidences of morbidity (61.5%), while 31 (5.5%) patients with SAS from 9 to 10 had 3 morbidity occurrences (9.7%). Results show that 30-day postoperative morbidity is inversely related to increasing SAS (P < .0001). Furthermore, lower SAS was associated with significantly increased operative time (SAS 0-4: 9.3 ± 2.6 hours vs SAS 9-10: 3.0 ± 1.1 hours) and lengths of stay (SAS 0-4: 10.0 ± 7.3 days vs SAS 9-10: 1.6 ± 1.0 days), P < .0001. SAS remained highly significant after adjusting for potential confounding variables in the multivariable analysis (P < .0001).

An increasing SAS is associated with significantly lower rates of 30-day postoperative morbidities in a noncutaneous HNSCC patient population.

To investigate clinicopathologic and treatment factors associated with survival in adult head and neck sarcomas in the National Cancer Database (NCDB). To analyze whether treatment settings and therapies received influence survival outcomes and to compare trends in utilization via an aggregated national data set.

Prospectively gathered data.

NCDB.

The study comprised a total of 6944 adult patients treated for a head and neck sarcoma from January 2004 to December 2013. Overall survival (OS) was the primary outcome.

Increased age and tumor size, nodal involvement, and poorly differentiated histology had significantly reduced OS (P < .001). Angiosarcoma, malignant nerve sheath tumor, malignant fibrous histiocytoma, osteosarcoma, and rhabdomyosarcoma histologic subtypes had significantly reduced OS, while liposarcoma, chondrosarcoma, and chordoma had improved OS (P < .001). Utilization of surgical therapy was associated with improved OS, while positive surgical margins were associated with treatment at a community-based cancer program and had reduced OS (P < .001). On multivariate analysis, treatment with radiation and/or chemotherapy was not significantly associated with OS; however, primary treatment with definitive chemoradiotherapy had significantly reduced OS. Patients treated at academic/research cancer programs (n = 3874) had significantly improved 5- and 10-year OS (65% and 54%, respectively) when compared with patients treated at community-based cancer programs (n = 3027; 49% and 29%; P < .001). The percentage utilization of these programs (56% vs 44%) did not change over the study period.

For adult head and neck sarcomas, treatment at an academic/research cancer program was associated with improved survival; however, despite increasing medical specialization, the percentage utilization of these programs for this rare tumor remains constant.

To examine the impact of treatment setting and demographic factors on oropharyngeal and laryngeal cancer time to treatment initiation (TTI).

Retrospective case series.

Safety net hospital and adjacent private academic hospital.

Demographic, staging, and treatment details were retrospectively collected for 239 patients treated from January 1, 2014, to June 30, 2016. TTI was defined as days between diagnostic biopsy and initiation of curative treatment (defined as first day of radiotherapy [RT], surgery, or chemotherapy).

On multivariable analysis, safety net hospital treatment (vs private academic hospital treatment), initial diagnosis at outside hospital, and oropharyngeal cancer (vs laryngeal cancer) were all associated with increased TTI. Surgical treatment, severe comorbidity, and both N1 and N2 status were associated with decreased TTI.

Safety net hospital treatment was associated with increased TTI. No differences in TTI were found when language spoken and socioeconomic status were examined in the overall cohort.

The purpose of this study was to analyze computed tomography (CT) and magnetic resonance (MR) images and to evaluate the maximum standardized uptake value (SUV max) of positron emission tomography (PET)/CT parameters between sinonasal non-Hodgkin’s lymphoma (NHL) and squamous cell carcinoma (SCC), knowing the imaging features that distinguish sinonasal NHL from SCC.

Case series with chart review.

University tertiary care facility.

We analyzed the features on CT, MR imaging, and PET/CT of 78 patients diagnosed with sinonasal NHL or SCC histopathologically. The CT (n = 34), MRI (n = 25), and PET/CT (n = 33) images of 39 patients with sinonasal NHL and the CT (n = 38), MR (n = 28), and PET/CT (n = 31) images of 39 patients with SCC were evaluated. The sinonasal NHL was diagnosed as natural killer/T-cell lymphoma (n = 28) and diffuse large B-cell lymphoma (n = 11).

Patients with sinonasal NHL had a larger tumor volume and higher tumor homogeneity than patients with SCC on T2-weighted and postcontrast MR images. Most of the sinonasal NHL and SCC showed a high degree of enhancement. The apparent diffusion coefficient (ADC) values and adjacent bone destruction were significantly lower in sinonasal NHL than in SCC. However, cervical lymphadenopathy, Waldeyer’s ring involvement, and PET/CT SUV max showed no significant differences between sinonasal NHL and SCC.

CT and MR images of sinonasal masses showing a bulky lesion, marked homogeneity, and low ADC values without adjacent bone destruction are more suggestive of sinonasal NHL than SCC.

To characterize industry payments to otolaryngologists in 2016 versus 2014 and 2015.

Cross-sectional retrospective analysis.

Open Payments Database.

Using the Open Payments Database, we identified otolaryngologists receiving payments from industry sponsors from 2014 to 2016. We characterized the number and value of payments per physician overall and by census region, as well as by sponsor subspecialty and payment type. Study years were compared via analysis of variance and Kruskal-Wallis tests. Trends in payments to otolaryngologists were compared with trends in 21 other specialties.

Payment to otolaryngologists increased 67% from 2014 to 2016—from $8.7 million in 2014 to $9.9 and $14.5 million in 2015 and 2016, respectively (P < .001). While mean payment per compensated otolaryngologist increased ($1095, $1243, and $1834 in 2014, 2015, and 2016, respectively, P < .001), median payments stayed relatively constant ($169, $165, and $172), suggesting an increasingly unequal distribution. Much of the increase is accounted for by an increased number of payments for consulting fees and physician ownership. Most payments were made by companies specializing in rhinology. Otolaryngology received the lowest industry compensation per physician among the surgical specialties examined and lower compensation than most nonsurgical specialties. The increase in payments to otolaryngologists was proportionally greater than all but 1 of the other 21 specialties examined.

Industry compensation to otolaryngologists is increasing and increasingly unequal, although it is still less than that in most other specialties. In otolaryngology, the Open Payments Database has not decreased physician-industry relationships as intended.

To evaluate the short- and long-term effects of tricyclic antidepressants (TCAs) and gabapentin in the treatment of unexplained chronic cough (UCC).

Prospective cohort.

Tertiary care hospital.

Patients seen between July 2016 and March 2017 were included following a formal workup and clinical evaluation indicative of UCC. Patients were placed on either a TCA (amitriptyline or nortriptyline) or gabapentin. Leicester Cough Questionnaire (LCQ) and percentage improvement scores were obtained prior to treatment initiation and at 2 and 6 months of neuromodulator treatment. A linear mixed model assessed the change in LCQ score between the 2 treatment time points and baseline scores.

Twenty-eight patients completed a total of 37 neuromodulator trials. Gabapentin demonstrated statistically significant improvement in LCQ scores at 2 months (2.48 points, P≤ .01) and 6 months (5.40 points, P = .01) of treatment as compared with baseline. Patients taking TCAs demonstrated statistically significant improvement of LCQ scores at 2 months of treatment (3.46 points, P≤ .01). However, the majority of patients discontinued treatment, most commonly secondary to the development of tachyphylaxis after 2 months, precluding analysis at 6 months.

While both neuromodulator classes demonstrated short-term benefit, the majority of patients discontinue treatment prior to 6 months, with patients taking TCAs discontinuing more frequently than patients on gabapentin. Future investigations are warranted evaluating tachyphylaxis and the utility of dual treatment therapies designed to address peripheral and central sensory pathways involved in UCC.

To compare the ability of the dynamic voice computed tomography (CT) scan to characterize laryngeal function in airway reconstruction patients vs bedside endoscopic nasopharyngolaryngoscopy and videolaryngostroboscopy.

Case series with chart review.

Pediatric tertiary care center.

Retrospective case series of children and young adults with a history of complex airway surgeries with subsequent dysphonia. We analyzed clinical data for all patients who underwent an airway reconstruction procedure between January 1, 2010, and April 30, 2016, and also had a dynamic voice CT and bedside endoscopic exam during the same period.

Twenty-four patients were analyzed (4 male, 20 female) with a mean age of 15.1 years (95% confidence interval [CI], 12.9-17.22). Patients had a mean of 2.2 airway surgeries (95% CI, 1.8-2.6), with 62.5% of them being open procedures. Laryngotracheoplasty with a cartilage graft was the most common procedure (40.0%). The pattern of laryngeal closure could be detected in all cases with the dynamic CT scan (n = 24/24, 100%) compared to 87.5% (21/24) with the standard endoscopic examination (P = .04). The location of gap closure could be detected in all cases (24/24) with the dynamic voice CT while 20.8% (5/24 patients) could not be rated with standard endoscopy/stroboscopy (P = .02). Dynamic voice CT was able to assess the vertical closure pattern of the glottis 100% (24/24) while it could be detected in 83.3% (20/24) cases with endoscopic study (P = .04).

Dynamic voice CT shows promise as an additional tool for evaluation of patients with a history of complex airway procedures by providing complementary information.

To determine the prevalence of chronic rhinosinusitis–related symptoms in the United States.

Cross-sectional analysis of a national database.

Representative sampling of the US adult population.

The National Health and Nutrition Examination Survey data set, taste and smell supplement 2013-2014 was analyzed for sinonasal question responses regarding discolored nasal mucus, nasal blockage, sinus pain, and dysosmia. The individual prevalences as well as the prevalence of 2 or more of these symptoms (which would be compatible with a diagnosis of chronic rhinosinusitis) were determined for the US population.

After excluding adults with an intercurrent head cold, 113.5 million adults (mean age 58.2 years; 52.6% female) were analyzed. Individual symptom prevalences were dysosmia (9.17 million, 8.1%), nasal blockage (6.9 million, 6.0%), sinus pain (2.37 million, 2.1%), and discolored mucous (1.28 million, 1.1%). Overall, 14.8 million (13.0%) adults had exactly 1 sinonasal symptom, and 2.37 million adults (2.1%) responded with 2 or more cardinal symptoms for chronic rhinosinusitis. With respect to sex, 1.9% of males reported 2 or more symptoms compatible with chronic rhinosinusitis vs 2.2% of females (P = .690), which is not statistically significant.

Of US adults, 2.1% meet symptom criteria for the potential diagnosis of chronic rhinosinusitis at any given time. Further objective corroboration with a physical exam and determination of duration of symptoms would be required to determine the true prevalence of chronic rhinosinusitis, but this point prevalence represents the potential population at risk for chronic rhinosinusitis in the United States.

Hearing loss following temporal bone (TB) fracture may result from direct transection of the middle and inner ear. The pathophysiology of hearing loss due to head injury without TB fracture, however, is not well understood. Few reports describe otopathologic findings. Herein, we investigate the pathologic findings of patients who sustained a head injury without evidence of a TB fracture.

Otopathology study.

Otopathology laboratory.

Subjects with a history of head injury without TB fracture.

The TBs of patients with head injury were evaluated by light microscopy. Inner ear anatomy was evaluated, including counts of spiral ganglion cells (SGCs), hair cells, pillar cells, atrophy of the stria vascularis, and the presence of endolymphatic hydrops. SGC counts were compared with those of historical age-matched controls.

All cases (N = 6 TBs) had evidence of inner ear pathology. Of the 6 cases, 2 (33%) had severe loss of hair cells in all 3 turns of the cochlea, and 4 (67%) cases demonstrated moderate to severe loss at the basal turn of the cochlea. Four cases had scattered atrophy of the stria vascularis, and 3 (50%) had cochlear hydrops. The number of total SGCs was decreased, with an average 53% loss (range, 25%-79%) as compared with controls. The SGC count loss was evenly distributed along Rosenthal’s canal.

Patients with a history of head injury without TB fracture demonstrate inner ear pathology. Further studies are necessary to determine if otopathology findings are directly attributable to trauma.

(1) Assess 3-dimensional volumetric growth of untreated sporadic vestibular schwannomas (VSs) in a large cohort of patients treated with conservative observation. (2) Compare volumetric and conventional linear diameter measurements for detecting tumor growth.

Case series with chart review.

Tertiary skull base referral center.

Patients with sporadic VS who elected initial conservative treatment with at least 2 serial magnetic resonance imaging (MRI) scans were included. Tumor volume was determined with 3-dimensional segmentation of MRI sequences. The volumetric threshold for tumor growth was an increase ≥20% from baseline tumor volume. Tumor size based on linear diameter was assessed with the 1995 American Academy of Otolaryngology—Head and Neck Surgery Foundation guidelines for VS outcome reporting, with growth defined as an increase ≥2 mm.

A total of 361 patients were included with a median radiologic follow-up of 4.1 years (interquartile range [IQR], 2.5-6.8). At diagnosis, 232 VSs (64%) were purely intracanalicular, and 129 (36%) extended into the cerebellopontine angle. The median baseline tumor volume was 0.161 cm³ (IQR, 0.054-0.418). Overall, 69% of tumors demonstrated volumetric growth at a median of 1.1 years (IQR, 0.6-2.1) after initial MRI. In contrast, based on linear measurement assessment, 48% of tumors demonstrated growth at a median of 1.8 years (IQR, 0.8-3.1) from first MRI scan. Disequilibrium, facial hypoesthesia, aural fullness, initial tumor size, and nonincidental diagnosis were associated with tumor growth.

Three-dimensional volumetric assessment of VS provides a more sensitive measure of tumor growth when compared with linear diameter assessment. Through volumetric analysis, the current study revealed that a significant proportion of VSs demonstrate growth during observation.

(1) Compare lateral skull base (LSB) height/thickness in patients with spontaneous cerebrospinal fluid otorrhea (CSF), superior canal dehiscence (SCD), acoustic neuromas (AN), and otosclerosis (OTO). (2) Perform correlations between age, body mass index (BMI), sex, and LSB height/thickness.

Case series with chart review.

Tertiary referral center.

Patients with CSF, SCD, AN, and OTO diagnosed from 2006 to 2016 were included if they had high-definition temporal bone computed tomography (CT) and absence of trauma, radiation, chronic ear disease, and/or congenital anomaly. CT-based measurements included LSB height/thickness and pneumatization rates overlaying the external auditory canal (EAC), tegmen tympani (TgT), perigeniculate region (PG), and internal auditory canal (IAC). LSB height/thickness, age, sex, and BMI were statistically correlated. In total, 256 patients and 493 ears (109 CSF, 115 SCD, 269 AN/OTO) were measured.

Patients with CSF had significantly higher BMIs than the other groups (P < .001). Patients with CSF and SCD had similar radiographic LSB phenotypes at most measured locations. Both groups exhibited a significantly lower LSB height compared to the AN and OTO groups (mean, 3.9-4.2 mm vs 4.9-5.6 mm; P < .001). Patients with CSF and SCD also demonstrated significantly lower pneumatization rates, as low as 17% to 23% overlaying the PG and IAC (P < .001). There were no statistically significant correlations found between age, sex, BMI, and LSB height/thickness at any measurement location in any group.

Patients with CSF and SCD exhibit similar radiographic LSB phenotypes. Age, sex, and BMI do not significantly correlate with LSB height/thickness. These data support the theory that CSF and SCD arise via similar congenital pathoetiologic mechanisms.

To characterize the epidemiology of pediatric salivary cancer and associate patient, tumor, and treatment factors with treatment modality and survival.

Cross-sectional analysis.

US national database.

We identified 588 patients 19 years or younger diagnosed with salivary cancer in the National Cancer Database 2004-2013. We characterized patient, tumor, and treatment factors as proportions and associated these factors with treatment modality and overall survival via multivariable logistic regression and multivariable Cox proportional hazards regression, respectively.

In total, 588 patients were included. Mucoepidermoid carcinoma was identified in 234 of 588 patients (40%) and acinar cell carcinoma in 215 of 588 (37%). Parotid tumors were seen in 504 (86%) of patients. Surgery alone was used to treat 351 (60%) of patients; surgery plus adjuvant radiation was used to treat 145 (25%). Overall 5-year survival was 93%. Controlling for patient and tumor characteristics, treatment with surgery and radiation vs surgery alone was associated with improved overall survival (hazard ratio [HR] = 0.15; 95% confidence interval [CI], 0.02-0.92; P = .041). High tumor grade was associated with decreased overall survival (HR = 33.17; 95% CI, 5.89-186.8; P < .001). Treatment with surgery plus radiation remained associated with improved overall survival in the subset of patients with high tumor grade (HR = 0.12; 95% CI, 0.02-0.64; P = .014).

Tumor grade is an important predictor of survival in pediatric patients with salivary gland cancer. Surgery plus adjuvant radiation vs surgery alone is associated with improved overall survival and may be considered for high-risk patients, particularly those with high-grade tumors.

The objective of the present study is to examine the impact of supraglottoplasty on the quality of life (QOL) of caregivers and infants with severe laryngomalacia and moderate laryngomalacia with feeding difficulties.

Prospective cohort study.

Tertiary children’s hospital.

Thirty-nine infants who underwent supraglottoplasty were examined. The primary caregiver answered the 47-item short form of the Infant and Toddler Quality of Life Questionnaire–47 pre- and postoperatively; the subsection scores were compared. A 1-way analysis of variance was performed to analyze the effect of age and sex. A comparison was made between our cohort and a general population of healthy children.

The average age at surgery was 4.0 months, and 53% of the patients were male. There was significant postoperative improvement in overall health, physical ability, growth and development, bodily pain, temperament, emotional impact on the caregiver, impact on caregiver’s time, and family cohesion scores (P < .05). The same subscale scores remained significantly improved postoperatively after age and sex were controlled. Preoperative QOL scores were significantly worse than those of the general population in nearly all categories. Postoperative physical ability (P = .009) and temperament (P = .011) QOL scores were higher than the those of the general population. Scores for growth and development (P = .132), bodily pain (P = .481), and family cohesion (P = .717) were equivalent to those of the general population.

QOL was significantly improved after supraglottoplasty for infants with severe laryngomalacia and moderate laryngomalacia with feeding difficulties. After supraglottoplasty, QOL was similar to that of the general infant population in most categories.

Identify methods to improve the frozen-section diagnosis of acute invasive fungal rhinosinusitis.

Biopsies with frozen section for suspected acute invasive fungal rhinosinusitis were reviewed to identify causes for missed diagnoses and evaluate methods for potential improvement.

All aspects of the study were performed at the Penn State Milton S. Hershey Medical Center.

All frozen sections performed for suspected acute invasive fungal rhinosinusitis between 2006 through 2017 were reviewed with their diagnoses compared to the final diagnoses. Sensitivity and specificity were determined for each biopsy specimen to evaluate the diagnostic method and for each patient for its effectiveness on outcome. Causes for frozen-section failures in diagnosis were identified. A periodic acid–Schiff stain for fungus (PASF) was modified for use on frozen tissue (PASF-fs) and applied both retrospectively and prospectively to frozen sections to determine its ability to identify undetected fungus and improve diagnostic sensitivity.

Of 63 biopsies positive for acute invasive fungal rhinosinusitis, 51 were diagnosed on frozen section, while 61 were identified by including the novel PASF-fs stain, reducing the failure rate from 19% to 3%. Of 41 cases that were positive, 34 were diagnosed on frozen section. Of the 7 that were not, 5 were identified by including the PASF-fs, reducing the failure rate from 17% to 5%.

Frozen section interpretation of biopsies for suspected acute invasive fungal rhinosinusitis using a PASF-fs stain should enable a rapid and accurate diagnosis with improved outcomes by shortening the time to surgery.

To identify whether TIM-3 expression is present in the mast cell population within nasal polyps and to determine its correlation with clinical severity in patients with chronic rhinosinusitis with nasal polyposis.

Basic science, translational study.

Nasal polyp tissue collected from patients seen at a tertiary care hospital (2015-2016).

Nasal polyp tissue obtained during functional endoscopic sinus surgery (n = 24) was enzymatically digested into epithelial and stromal fractions. Viable mast cells expressing TIM-3 were identified using flow cytometry for the following: CD45, Live/Dead, c-kit, FcεR1, TIM-3. Disease severity was assessed using the Sino-Nasal Outcome Test, Lund-Mackay staging system, Lund-Kennedy staging system, and complete blood counts.

Mast cells were found in both the epithelial and stromal layers of polyps, with a greater %TIM-3⁺ mast cells in the epithelial layer compared with that of the stromal layer (P = .001). As the percentage of mast cells increased, there was a comparative worsening in endoscopic severity after comparing pre- and postoperative LK scores (ρ = −0.455, P = .029). In a subgroup of patients with concomitant asthma, increased epithelial %TIM-3⁺ mast cells also correlated with worsening endoscopic appearance postoperatively (ρ = 0.866, P = .001, n = 11). Oral corticosteroid treatment did not change the viability of mast cells nor their influence on the increased postoperative endoscopic disease severity (ρ = −0.544, P = .020, n = 18).

Viable mast cells were found to be present in polyps with increased TIM-3 expression at the epithelial layer. This suggests that TIM-3 may play a role in chronic inflammation in CRSwNP via mast cell activation.
