成人病理嗓音电声门图曲线的临床特点

The clinical characteristic of electroglottography curves of pathological voice in adult

目的 :探讨成人病理嗓音电声门图 (EGG)曲线的临床特点。方法 :对 4 5 3例病理嗓音进行EGG检测 ,分析异常EGG曲线的临床意义。结果 :病理嗓音EGG曲线表现 :①EGG周期由接触期 (CP)和开放期 (OP)组成 ,二者比值界于一定范围 ,CP/OP <0 .70或 >2 .95均为异常 ;②CP又分为接触渐闭相 (CCP)和接触渐离相(COP) ;OP又分为渐开开放相 (OOP)和开放渐触相 (OCP) ;③振动周期中各时相形态异常表现 :CCP平缓、CCP切迹、波峰平坦、COP陡直、COP切迹、COP隆起、OOP隆起、OCP隆起 ;④联波、不规则等情况虽然少见 ,但反映了病理嗓音的特殊振动模式 ;⑤总的各时相异常变化中 ,COP >OP >CCP ,各病理嗓音组呈现不同的特点 ;⑥部分病理嗓音表现为联合异常 ,以COP与OOP联合病变为最多 ,单或双侧声带息肉、Reinke水肿及声门型喉癌组均有相当比例的联合病变。结论 :成人病理嗓音EGG曲线的形态变异错综复杂 ,各种变异形式又有一定的内在联系。确立OP的异常形式增加了病理EGG检出率 ,并且与CP异常密不可分 ;不同病理嗓音EGG曲线异常呈现不同倾向性 ,有一定规律可循。确立病理嗓音EGG曲线各时相形态异常变化形式 ,综合分析病理声带的异常振动模式 。

Objective: To discuss the clinical characteristic of Electroglottography (EGG) curves of pathological voice in adult.Method: Four hundred and fifty-three adults with pathological voices were examined by EGG and the abnormal EGG curves were analyzed. Result:①the EGG cycle was composed of contact phase (CP) and open phase (OP), the ratio of CP/OP was between 0.70 to 2.95,otherwise it was abnormal;②the CP was composed of closing-contact phase (CCP) and contact-opening phase (COP); the OP was composed of opening-open phase (OOP) and open-closing phase (OCP); ③the abnormal formations of every phases in vibration cycle contained:smooth CCP, notches in CCP, flat in wave peak, steep COP, notches in COP, knurls in COP, knurls in OOP and in OCP; ④duplicate waves and irregular waves were fewer, but they reflected the special vibratory patterns of pathological voices; ⑤Each abnormal formation fell as the follow:COP>OP>CCP.Each pathological voices presented different characteristics; ⑥combined variance appeared in part pathological voices, such as single vocal polyps, double vocal polyps, Reinke edema and glottic laryngocarcinoma.COP combined with OOP was the most usual.Conclusion: The abnormal variance formations of EGG curves of pathological voices in adult are intricate and they have inherent relations with each other. The establishment of OP variance increases the pathological EGG and the OP abnormities is CP abnormities.There are different orientations and rules in different pathological voices.
