摘要
目的探讨声带息肉及声带小结患者发声时最小声门面积(minimum glottal area,MGA)与声学及空气动力学指标的相关性。方法对50例正常人(正常组,女30例,男20例)、35例声带息肉患者(息肉组,女20例,男15例)及36例声带小结患者(小结组,均为女性)进行频闪喉镜检查,应用配套KIPS软件计算发/i:/音时MGA;采用计算机语音工作站(Computerized Speech Lab 3700,CSL3700)及空气动力学嗓音功能分析仪(Aero-phone II Voice Function Analyzer)测试息肉组和小结组患者的基频微扰(jitter)、振幅微扰(shimmer)、谐噪比(har-mony to noise ratio,HNR)、平均气流率(mean airflow rate,MFR)、声门阻力(glottal resistance,Rg)、声门下压力(subglottal pressure,SGP),并分别与发声时MGA进行相关性分析。结果正常女性发声时MGA为258.85±116.19,明显小于小结组(463.86±135.25)(P<0.05);正常组发声时MGA为308.25±158.53,明显小于声带息肉组(592.03±299.20)(P<0.05)。小结组发声时MGA与声门下压力无明显相关性(r=0.060,P>0.05);息肉组发声时MGA与声门下压力呈正相关关系(r=0.997,P<0.05)。息肉组及小结组发声时MGA分别与基频微扰(r=0.968,P<0.05和r=0.990,P<0.05)、振幅微扰(r=0.981,P<0.05和r=0.996,P<0.05)及平均气流率(r=0.995,P<0.05和r=0.996,P<0.05)呈正相关,与声门阻力(r=-0.998,P<0.05和r=-0.992,P<0.05)及谐噪比(r=-0.996,P<0.05和r=-0.992,P<0.05)呈负相关。结论声带息肉及声带小结患者发声时MGA增大,声门闭合不良是其声嘶的重要原因之一。
