Background and Objectives：Palatal muscle resection (PMR) is a surgical method that treats retropalatal airwayobstruction. Sometimes elongated uvula can aggravate obstructive symptom in obstructive sleep apnea (OSA)patients. Uvulectomy is usually done in such cases to resolve the obstructive effect of the uvula. The purpose ofthis study was to compare postopreative results of PMR and PMR with partial uvulectomy in treating obstructivesleep apnea (OSA). Materials and Methods：Thirty-three patients with OSA due to retropalatal obstruction weretreated with surgical method from June 2011 to May 2013. Seventeen patients underwent PMR and 16 patientsunderwent PMR with partial uvulectomy. Surgical method was decided by preoperative drug induced sleep en-doscopy (DISE) analysis. Postoperative satisfaction criteria were analyzed before and after 3 months of each sur-gery via questionnaires based on visual analogue scale (VAS) of snoring, sleep apnea, and daytime sleepiness. Post-operative complications were analyzed before the surgery as well as 1, 4, and 12 weeks after the surgery viaquestionnaires based on VAS about foreign body sensation, dry throat, velopharyngeal insufficiency, swallowingdifficulty, and voice change. Results：Postoperative satisfactions were significantly (p＜0.05) improved in bothgroups. There was no significant (p＞0.05) difference in postoperative satisfactions between the two groups. For-eign body sensation and dry throat were significantly (p＜0.05) increased in PMR with partial uvulectomy group. But these complications were resolved within 3 months. Conclusions：The PMR with partial uvulectomy grouphad more complications than the PMR group. Our results suggested that PMR with partial uvulectomy was pref-erable for cases requiring uvulectomy because some complications were resolved spontaneously
