Design: According to the diagnostic criteria published by Chinese medical association of otolaryngology-head and neck, 21 cases were performed UPPP with the harmonic scalpel. The Regional Ethics Committee of our hospital approved the study protocol. Informed written consent was obtained from all participants. Setting: A single specialist hospital. Participants: 21 patients with OSAHS. Participants were not randomized in groups and were performed UPPP with the harmonic scalpel. Main Outcome Measures: Part of the uvula muscle and the anterior wall of the uvula mucosa were removed, and the mucosa of posterior wall was preserved. The mucosa of the posterior wall was sutured with the remaining part of the anterior wall. The AHI and LaSO<sub>2</sub> were measured both before and six months after the operation by Polysomnography (PSG). Results: This study reported a significant improvement (p ± s) was 48.6 ± 12.65, and LSaO<sub>2</sub> (± s) was 67.4% ± 9.18%;postoperative AHI was 10.9 ± 9.29, and postoperative LSaO<sub>2</sub> was 91.0 ± 1.47. The mean operation duration was 30.1 minutes. Conclusion: The use of HS in UPPP is efficient and shows some advantages over conventional method: its use provided a blood free surgery field, and shorter operation duration.展开更多
