Objectives: This study investigated the outcomes of uvula-preserving palatopharyngoplasty (UPPPP) in patients with obstructive sleep apnea syndrome (OSAS).
Methods: Twenty men with obstructive sleep apnea syndrome received the UPPPP operation at our institution. We measured symptom changes after UPPPP using a visual analog scale (VAS), and all patients were examined with polysomnography pre- and post-operatively. ’Surgical success’ was defined as reduction in apnea-hypopnea index (AHI) to below 20 events per hour and more than 50% post-operative reduction.
Results: Snoring decreased significantly (6.7±2.3 to 3.7±2.9 on VAS, P=0.002) but the postoperative globus sense did not differ from that preoperatively (2.0±2.4 to 2.1±2.7 on VAS, P=0.79). Apnea and apnea-hypopnea indices were significantly reduced after UPPPP (34.7±20 to 24.2±17.2 events/hour, P=0.029). The surgical success rate was 40% regardless of Friedman stage. There was significant reduction in the AHI on supine sleep in both surgically successful and unsuccessful patient groups.
Conclusion: UPPPP may minimize postoperative globus sense and other complications, with a success rate comparable to that of previously reported surgical methods in OSAS patients. In addition, it may reduce the apnea-hypopnea index in the supine sleep position.
