Zhejiang Medical University,Hangzhou,310009） Objective To improve the diagnosis and treatment of arytenoid subluxationfollowing endotracheal intubation.

目的 提高对气管插管后环杓关节半脱位诊断和治疗的认识。

Subtotal laryngectomy with preservation of arytenoid cartilage is recommended for T3 laryngeal cancer.

手术的关键是不能损伤杓状软骨及喉返神经，设计好环咽吻合方案。

Objective:To identify chronologic changes in the histomorphometry and structure of the chronically denervated posterior cricoarytenoid muscle.

目的：动态地观察单侧喉返神经切断后，健侧环杓后肌酶组织化学和结构的改变。

Result :There was no significant difference between sexes,ages and sides.The fibrillation potential amplitude was maximum at 3 to 4 months after denervation of the posterior cricoarytenoid muscle or at 5 to 6 months after denervation of the thyroarytenoid muscle and still remained at certain level for years in some patients.Significant difference was showed in complete and incomplete nerve injuries groups,but changes of amplitude with time in incomplete nerve injuries group were small.

结果：不同性别、年龄及不同侧的纤颤电位波幅间的差异无显著性，失神经环杓后肌纤颤电位波幅均值在病程2～＜4个月时最高，而失神经甲杓肌纤颤电位波幅均值在病程4～＜6个月时最高，相当一部分患者的纤颤电位波幅晚期仍维持一定水平，并且神经完全损伤者和不完全损伤者各时间纤颤电位波幅均有显著性差异，而神经不完全损伤者各时间幅度变化小。

Fifty-four patients (65 sides) with recurrent laryngeal nerve paralysis were examined and only the maximum fibrillation potential amplitudes were recorded in the posterior cricoarytenoid muscles and thyroarytenoid muscles.

对54例(共65侧)喉返神经麻痹患者的甲杓肌、环杓后肌行肌电图检查，记录最大纤颤电位波幅。

These two operations were both effective in the treatment of unilateral paralysis of vocal fold, but it should be selected according to the requirement of patient, the pattern of damage, the degree of paralysis and movement of cricoarythenoid joint.

两种术式均是治疗单侧声带麻痹的有效方法，但应根据患者的要求、损伤的方式、声带麻痹程度及有无环杓关节固定等情况进行选择合适的治疗方法。

In the United States, chronic alcoholism and hepatitis C are the most common ones.

在美国，慢性酒精中毒，肝炎是最常见的。
