OSAHS患者UPPP手术前后发声共鸣特征分析

摘要

目的：探讨阻塞性睡眠呼吸暂停低通气综合征（obstructive sleep apnea hypopnea syndrome ，OS-AHS）患者接受悬雍垂腭咽成形术（uvulopalatopharyngoplasty ，UPPP）前后，发声时的共鸣特征变化。方法使用多通道语音分析系统测试36名男性OSAHS患者（OSAHS组）UPPP手术前后、36名正常男性（正常对照组）发/a：/音时头腔、口腔、喉腔、胸腔各共鸣腔的频谱特征，分别统计0～999 Hz（FR1）、1000～1999 Hz（FR2）、2000～2999 Hz（FR3）、3000～4000 Hz（FR4）频段的能量分布。结果 OSAHS组 UPPP术后，头腔和口腔FR2能量值较术前提高（P＜0．05），术后头、口及胸腔 FR1能量值仍高于正常（P＜0．05），头腔（FR2、FR3、FR4）、口腔（FR2、FR3）、胸腔（FR2）各频段能量值低于正常对照组（ P＜0．05）。术后喉腔FR1～FR4能量值与术前及对照组比较差异无统计学意义（P＞0．05）。结论 UPPP手术通过解除OSAHS患者上气道的阻塞和咽腔塑形，主要改变了其头腔和口腔的共鸣特征，使头腔和口腔的高频共振加强。%Objective To study the influence of UPPP on resonance characteristics of four resonance cavity in patients with OSAHS .Methods Using multi-channel voice analysis system to test the cavity resonance character-istics and energy distribution of 36 OSAHS patients (including pre - and post -operative) and 36 normal males when they speak /a:/.The frequency spectrum was 4 000Hz(FR1 ,FR2 ,FR3 ,FR4 ) .Results FR2 energy values of the head cavity and mouth cavity of OSAHS patients heighten significantly after UPPP (P<0 .05);FR1 energy val-ues of head ,mouth and thoracic cavity were higher than that of in normal males'after UPPP(P<0 .05) .FR2 ,FR3 , FR4 energy values of head cavity ,FR2 ,FR3 energy values of mouth cavity ,FR2 energy values of thoracic cavity were lower than those of in normal males'after UPPP(P<0 .05) .Conclusion UPPP surgery removes the obstruction of the upper airway of OSAHS patients and changes the morphology of the pharynx ,thas changes the resonance charac-teristics of the head cavity and oral .
