摘　　要：【目的】探讨悬雍垂腭咽成形术(UPPP)对语音频谱的影响。【方法】对行UPPP的26例阻塞性睡眠呼吸暂停低通气综合征成年患者,分别在术前1周内和术后2个月左右行嗓音声学分析,获取手术前后6个基本元音[a]、[o]、[e]、[i]、[u]、[ü]的声学频谱,并对手术前后各声学分析参数值进行统计学对比。【结果】术后有2例患者的[a]元音和1例患者的[u]元音出现鼻音共振峰;[o]、[e]及[u]元音的第3共振峰术后下降,而[i]元音的第2共振峰和[e]元音的第4共振峰术后升高(P<0.05)。【结论】UPPP术后患者共振峰有较明显变化,对从事歌曲、播音等职业用声者可以产生一定影响,对该类患者行UPPP需慎重。Objective To investigate the effect of uvulopalatopharyngoplasty（UPPP） on the vocal frequency spectrum.Methods Twenty-six adult patients diagnosed as obstructive sleep apnea hypopnea syndrome underwent the UPPP.Acoustic analysis of vowels was made 1 week before and about 2 months after UPPP including [a],[o],[e],[i],[u],and [ü].The pre-and post-operative articulation results were analyzed statistically.Results Nasal formants were found in two subjects＇ vowel [a] and one subject＇s vowel [u].The third formant frequencies（F3） in vowel [o],[e],and [u] decreased statistically,while the second formant（F2） in vowel [i] and the fourth formant（F4） in vowel [e] increased statistically（P0.05）.Conclusion UPPP had significant impact on several formants,which was important in the management of patients with concerns about postoperative vocal quality,such as singers and professional speakers.
