Abstract
Objectives
This study aims to compare Chitogel® with topical corticosteroid versus PureRegen® gel on wound healing and postoperative outcomes in the treatment of chronic rhinosinusitis.
Methods
A double-blinded randomized controlled trial was performed with patients undergoing functional endoscopic sinus surgery who were prospectively recruited and randomized to receive Chitogel with triamcinolone to one side of the sinuses and PureRegen to the contralateral sinuses. The patients underwent endoscopic follow-up at 2, 6, and 12 weeks postoperatively. Patient factors including age, gender, smoking status, comorbidities (reflux, allergy, and asthma), and disease specific factor (chronic rhinosinusitis phenotype) were collected. Sinus ostial measurements, adhesions, mucopurulent discharge, edema, crusting, and granulation were assessed. A visual analogue scale questionnaire on quality of life was assessed in each follow-up appointment.
Results
A total of 40 patients were randomized. At 12 weeks, Chitogel had a 10.7 mm2 reduction in frontal sinus ostium area compared to 15 mm2 in the PureRegen group; Chitogel had a 2.2 mm2 increase in maxillary ostium area compared to 0.1 mm2 in the PureRegen group; Chitogel had a 27.6 mm2 reduction in area of the sinus ostium compared to 28.7 mm2 in the PureRegen group. However, these differences were not statistically significant. The difference between the two groups when analysing adhesion, mucopurulent discharge, mucosal oedema, crusting, granulation, and phenotype was not statistically significant. Patient self-directed grading on quality of life was not statistically significant.
Conclusion
Both Chitogel with triamcinolone and PureRegen have demonstrated to be great options to prevent adhesion, stenosis, and optimize healing. There were no clinical and statistical differences between both products in wound healing and postoperative outcomes in the treatment of chronic rhinosinusitis.
