摘要

目的探讨Praat软件及嗓音障碍严重程度指数(dysphonin severity index,DSI)对改良杓状软骨内收术治疗单侧声带麻痹疗效评估的意义。方法 65例单侧声带麻痹患者均于患侧行改良杓状软骨内收术。全部病例于手术前及术后3月、12月分别行DSI分析及以Praat软件分析基频(fundamental frequency,F0)、声音强度(intensity)、噪谐比(NHR)、基频微扰[包括:局部基频微扰(jitter local)、局部绝对基频微扰(jitter local absolute)、基频微扰间期系数5(jitter ppq5)]、振幅微扰[包括:局部振幅微扰(shi mmer local)、局部振幅微扰dB(shi mmer localdB)、振幅微扰间期系数5(shi mmer apq5)]。结果术后3月、12月患者F0、NHR、jitter local、jitter local absolute、jitter ppq5、shi mmer local、shi mmer local dB、shi mmer apq5较术前明显下降,差异均有统计学意义(均为P<0.05)。术后3月、12月声音强度(intensity)分别与术前相比差异均无统计学意义(均为P>0.05)。术后3月、12月DSI值较术前均有显著提高(均为P<0.05)。术后12月上述所有指标与术后3月相比,差异均无统计学意义(均为P>0.05)。结论 Praat软件及DSI可客观、有效地评估改良杓状软骨内收术治疗单侧声带麻痹的疗效,该术式治疗单侧声带麻痹远期效果稳定。
