摘　　要：文中收集了１９８６～１９９３年间９０例资料，其中正常对照组６０例、病态组３０例；病例中单、双侧声带麻痹各１２例，男声女调６例。用频谱分析及喉内肌电位检查来筛选病例、测试声学并测试电位参数。结果表明：一侧或双侧声带麻痹对基频（Ｆ０）的影响不恒定，有的升高、有的下降；真声音域有变窄倾向；假声音域明显变窄。一侧和双侧声带麻痹对Ｆ０、真声音域及假声音域的影响是一致的，经统计学处理无显著性差异。男声女调患者，单侧甲状软骨成形术（Ⅲ型）后音调明显下降，对真声音域无影响，但使假声音域明显变窄，这与单侧声带麻痹相似。In order to study the acoustric and potential indexes,90 cases were selected by means of frequency analysis and electromyography of intrinsic laryngeal muscles from 1986 to 1993.30 cases of them,were an abnormal group including 12 of cases of unilateral paralysis,12 bilateral paralysis and 6 men with high-pitched voice;And the other 60 were taken as the control group.The results showed that unilateral or bilateral paralyses had an inconsistent.either increasing or decreasing effects on F0,and made the chest voice range narrower and the head voice range markedly narrower.However,the effects of unilateral and bilateral paralyses on F0,and the chest and head voice ranges were similar.In the men with high-pitched voices after the type III unilateral thyrochondroplasty,one side vocal cord became flaccid,then the two sides had different tensions and the pitch markedly decreased.The surgery had no effects on the chest voice range,but head voice range narrowed significantly which was similar to the effects of unilateral paralysis of the vocal cord.
