1、嗓音声学检测的临床应用王明方1常捷燕1李宁1[摘要]目的应用声谱图对喉科临床嗓音疾病进行嗓音声学检测和分析，探讨嗓音声学分析在喉科及嗓音方面应用的规律。方法共检610例，其中正常85人，声带息肉162例，声带小结40例，慢性喉炎57例，环杓关节区肿胀86例，环杓关节错位46例，声带麻痹13例，声带炎肿64例，喉部肿物21例，其他病变36例。声谱图检测参数有：基频、第一、二、三共振峰、基音周期、平均微扰、频率均值、频率微扰商、频率变动幅度、振幅微扰商、谐噪比、音调微扰系数等十二个参数。结果病变各组与正常
2、组比较，谐噪比全部9组，振幅微扰商6组，频率均值、频率微扰商、音调微扰系数4组有统计学差异。结论表明谐噪比、频率微扰商、振幅微扰商、音调微扰系数可以作为对病变嗓音进行判定的指标，另外对声带息肉手术前后疗效判定有一定帮助。[关键词]嗓音疾病声学检测MeasurementofvoiceacoustictoclinicalappliedWangMingfangChangJieyanLining(DepartmentofOtolaryngology,thePeople’sHospital,Guilin,541
