摘要
观察轻度声音嘶哑老年人６０例及发音正常老年人４９例喉的形态及功能，以探讨老年人喉发音功能变化和衰退的临床特点。轻度音哑出现的平均年龄为６１岁，男女比例为４：１。声带闭合不全与吸烟无明显关系。老年人无诱因的声音嘶哑所出现的声带闭合不全形式以梭形裂隙最多见，主要是由于声带肌肉张力减退，出现声带松弛所致。
Abstract The laryngeal morphology and function of 60 cases with mild hoarseness and 49 cases with normal voice in elderly were observed in order to find the ralation between the clinical manifeatation of the phonetic functional changes and degeneration in aged patients.Mild hoarseness was found to appear at an average age of 61 years with the ratio of male to female of 4:1.Incomplete closure of vocal cord had no obvious relationship to smoking.The incomplete closure most commonly seen was spindle shaped fissure form in the hoarseness without precipitating cause in aged patients.It is mainly due to the decrease of muscle tone leading to the relaxation of vocal cord.
