Background:
Bioresorbable nasal packing is associated with a decreased incidence of adhesions and bleeding postoperatively after endoscopic sinus surgery (ESS). However, discomfort during postoperative debridement is still a major area of concern for patients. Our objective was to compare the efficacy of a peptide hydrogel to that of a chitosan-based polymer in reducing pain during debridement after ESS.
Methods:
A prospective, multicenter, randomized, blinded trial was conducted in adults undergoing bilateral total ethmoidectomy for chronic rhinosinusitis. Participants served as their own controls with each subject receiving the hydrogel in a randomized ethmoid cavity and chitosan-based polymer in the contralateral ethmoid cavity. Participants were evaluated at 1, 4, and 12 weeks postoperatively. Pain during debridement as well as endoscopic evaluation of mucosal healing and hemostasis were measured.
Results:
Thirty patients who underwent ESS were included in this trial. During the week 1 postoperative debridement, patients reported significantly less pain on the hydrogel-treated side compared to the chitosan-based polymer-treated side. There were no significant differences in bleeding severity, Lund-Kennedy scores, debridement time, or need for further intervention between the two groups.
Conclusion:
This study demonstrated the efficacy of a peptide hydrogel in minimizing pain during postoperative debridement.
