文摘目的探讨阻塞性睡眠呼吸暂停低通气综合征(obstructive sleep apnea-hypopnea syndrome,OSAHS)对患者嗓音的影响。方法应用多维嗓音分析软件分析45例重度OSAHS患者(OSAHS组)与38例正常人(正常组)嗓音基频相关指标、基频微扰相关指标、振幅微扰相关指标、噪声相关指标、扰动相关指标、次谐波成分指标、嗓音不规则性测量、嗓音中断测量8大声学指标间的差异,并分别检测并比较OSAHS组及正常组的发声空气动力学指标。结果OSAHS组与正常组的基频相关指标、扰动相关指标、次谐波成分指标、嗓音不规则性测量、嗓音中断测量指标差异无统计学意义(均为P>0.05)。基频微扰相关指标、振幅微扰相关指标及噪声相关指标OSAHS组明显高于正常组,其中,OSAHS组的基频微扰百分比、振幅微扰百分比、噪谐比、嗓音紊乱指数分别为1.611%±0.822%、4.124%(3.497%,5.341%)、0.149(0.141,0.165)、0.076(0.056,0.100);而正常组的基频微扰百分比、振幅微扰百分比、噪谐比、嗓音紊乱指数分别为0.471%±0.220%、2.621%(2.160%,2.969%)、0.131(0.114,0.140)、0.057(0.043,0.060)。基频变化系数、振幅微扰、噪谐比的ROC曲线下面积在相应指标类别中最大,可作为诊断OSAHS患者嗓音异常的重要声学指标,其值分别在1.134%、0.318 dB、0.141时灵敏性和特异性最高。空气动力学指标中平均气流率、声门下压正常组分别为0.17(0.1225,0.220)L/s、6.199±2.421 cm H2O,OSAHS组分别为0.215(0.17,0.26)L/s、7.850±1.867 cm H2O,正常组明显小于患者组(P<0.05)。正常组声门阻力、发声效率分别为40.1(29.975,61.345)cmH 2 O·L^-1·s^-1、666.895(537.485,842.058)ppm,OSAHS组分别为29.72(18.528,36.1025)cm H2O·L^-1·s^-1、359.96(247.575,531.035)ppm,正常组大于OSAHS组(P<0.05),声门下压为6.005 cm H2O时是检测OSAHS患者灵敏度和特异性较高的空气动力学指标。结论OSAHS患者声门闭合欠佳,声带振动不规律,嗓音声学分析及发声空气动力学检测可对OSAHS患者的发声功能进行客观评估,是检测OSAHS患者嗓音状况的重要方法。
