Abstract: Objective Pharyngeal stenosis as a postoperative complication following uvulopalatopharyngoplasty(UPPP)with coblation is rare and may be difficult to treat. This report explores the causes of pharyngeal stenosis and presents our experience in successfully treating it. Methods From November 2010 to August 2016, eight patients with pharyngeal stenosis(five cases of nasopharyngeal stenosis and three of combined nasopharyngeal and oropharyngeal stenosis)secondary to UPPP with coblation presenting to Peking Union Medical College Hospital were studied. All patients with grade Ⅲ nasopharyngeal stenosis and different levels of difficulty in nasal breathing, mouth breathing, and blowing of the nose, as well as hyponasal speech, snoring, apnea, anosmia, and dysphagia. They underwent scar resection surgery for nasopharyngeal stenosis, horizontal-to-vertical pharyngoplasty for oropharyngeal stenosis, and local pharyngeal-flap rotation. Nasopharyngeal hollow stents were maintained in situ for >6 months postoperatively. Results Over a follow-up period of 1-4.5 years, amelioration of all symptoms was observed in seven cases, and the nasopharyngeal diameter was maintained at about 2 cm. No case of velopharyngeal insufficiency was noted. One patient required retreatment after restenosis. Conclusion Improper operation with coblation can cause severe postoperative pharyngeal stenosis. Scar resection, local flap rotation, horizontal-to-vertical pharyngoplasty, and prolonged use of nasopharyngeal hollow stents are reliable methods for correction of pharyngeal stenosis following UPPP surgery.
