Effect of upper airway multi planar expansion surgeries on voice in patients with severe obstructive sleep apnea hypopnea syndrome

摘要: 目的:探讨上气道多平面扩容术对重度阻塞性睡眠呼吸暂停低通气综合征(OSAHS)患者嗓音的影响。方法:对26例重度OSAHS患者于上气道多平面扩容术前后,分别应用针对嗓音相关的主观调查问卷和嗓音频谱分析软件进行客观统计学分析。结果:主观调查问卷结果显示,26例患者上气道多平面扩容术后4例(15.4%) 出现短时间的轻度腭咽闭合功能不全所致的鼻腔反流现象,均于术后1 周内消失;3例(11.5%)术后发声有轻度鼻音增高,尤以术后1周内较明显而后逐渐消失;2例(7.7%)扁桃体Ⅲ度肥大者诉发声清晰度较前提高,原有轻微含糖音消失;总体评价是嗓音障碍指数量表、嗓音相关生活质量量表评分手术前后均无明显变化(P>0.05)。嗓音客观参数基频F0和F1、F2、F3及F4共振峰频率手术前后均无统计学差异。结论:上气道多平面扩容术能够解除重度OSAHS患者上气道的阻塞性因素,同时进行鼻腔和咽腔的塑形,在一定程度上改变了声道共鸣腔,但对重度OSAHS患者嗓音的主观心理听觉评估无明显变化,嗓音客观参数基频F0和F1、F2、F3及F4四个共振峰频率均无明显的变化。

Abstract: Objective: To investigate effect of upper airway multi planar expansion surgeries on voice in patients with severe obstructive sleep apnea hypopnea syndrome(OSAHS). Method: The voice evalutated by subjective questionnaires and voice spectrum analysis software were analyzed statistically in 26 patients with sevee OSAHS before and after upper airway multi planar expansion surgeries. Result: The investigation by subjective questionnaires showed that 4 of 26 cases (15.4%) presented with temporary nasal backstreaming resulted from mild velopharyngeal which vanished in a week after the operation, 3 cases (11.5%) with mild hypernasality which were obvious within 1 week and then gradually disappear; and 2 cases (7.7%)with tonsillar hypertrophy of degreeⅢ whose sound articulation improved. The overall evaluation was that there were no distinct differences in preoperative and postoperative scores of VHI and V-RQOL (P>0.05) and in preoperative and postoperative formant frequency of F0-F4.Conclusion: In severe OSAHS patients, the upper airway multi-planar expansion surgery can relieve the upper airway obstructive factor, reshape the nasal and pharyngeal cavity, and change resonance chamber in certain degree, but this surgery does not have significant impacts on either subjective voice changes or objective voice quality. -
