摘　　要：本实验应用德国产Ｗｏｌｆ－５０１２型喉动态镜、Ｗｏｌｆ－５３７０型彩色摄像机、日本产ＮＶ－６３３盒带式录像机、ＫＶ－１９ＦＸ．ＩＭＴ彩色监示器及丹麦产ＤＩＳＡ－１５００型肌电图仪，对４６例间接喉镜下单侧声带固定于某一位置的患者进行粘膜波动、杓状软骨活动及喉内肌电位检查。结果发现：４６例均为单侧喉返神经麻痹，其中完全麻痹１２例占２６．０９％，部分麻痹３４例占７３．９１％。１２例完全麻痹中粘膜波动消失者５例占４１．６７％；３４例部分麻痹中粘膜波动消失者３例占８．８２％。经统计学检验，两者差异有显著性（Ｐ＜０．０５）．因此．单侧喉返神经麻痹的粘膜波动消失与麻痹程度有一定关系，完全麻痹中粘膜波动消失者多，部分麻痹中粘顺波动消失者少，但完全麻痹中也有粘膜波动存在者。１２例喉返神经完全麻痹中构状软骨固定者２例占１６．６７％，３４例部分麻痹中构软骨固定６例占１７．６５％，经统计学检验，差异无显著性（Ｐ＞０．０５）。因此，单侧喉返神经完全麻痹和部分麻痹均可致杓状软骨固定。The normal wave of vocal fold,mobilities of arytenoid and electromyographic signs of intrinsic laryngeal muscles in 46 cases with unilateral recurrent nerve paralysis were observed by means of laryngostroboscope and electromyograph in this study.The result shows that 12 cases of 46(26.09%)are complete unilateral recurrent nerve paralysis,the rest (73. 91%)is partial one.8 cases have no mucosal wave,of which 5 cases with complete paralysis,3 cases with partial one.There is significant difference in statistics(p<0.05)between 5/12(41.67%) and 3/34(8.82%).therefore the disappearance of mucosal wave in unilateral recurrent nerve paralysis has some rela tionship with the paralysis degrre and it occurs more frequent in complete paralysis than in partial one.But there may be mucosal wave in complete one. 2 cases of 12 with complete paralysis have arytenoid ankylosis and 6 cases of 34 with partial paralysis have arytenoid ankylosis. there is non significant difference between 2/12(16. 67%)and 6/34(17.65%)in statistics(p>0.05).therefore the arytenoid ankylosis may occur in both complete and partial recurrent nerve paralyses.
