目的 探讨晚期喉癌患者喉切除术后保留喉发声功能以提高生存质量，方法 对１７例晚期喉癌行喉近全切除术（Ｐｅａｒｓｏｎ手术）手术中，保留一侧杓状软骨及一条宽约１．５ｃｍ的与气管相连的粘膜条形成发声管，Ｎ０期患者规探查颈动脉分叉处淋巴结，根据冰冻病检结果而决定是否行颈淋巴清扫术，结果：术后１２例发声良地，除１例外均无明误吸现象，２年，３年及５年生存率分别为７０．６％，６２．４％，５０％，结论：Ｐｅａｒｓ

Clinical observation of curative effect of neartotal larynegectomy for advance laryngeal cancer

To explore a method how to preserve the speech function affer larynegectomy for advance laryngeal cancer and to improve the patients'life quality. Method: 17 cases with advance laryngeal cancer (T3 11 cases,T4 6 cases,glottic region 8 cases,supraglottic region 5 cases,pyriform recess 4 cases) were treated with neartotal larynegectomy (Pearson operation) in our department from February 1990 to July 1995. In the operations the remained monolateral arytenoid cartilage and an about 1. 5 cm-wide mucomembranous flap,which joined to trachea, reconstructed vocal duct, lymphoglandulae near the branch of neck artery were checked routinely in those No cases,and the radical neck dissection was taken or not according the result of frozen section. Result: After the operation good speech function was obtained in 12 cases. All patients, except one, had goodswallowing. Survival rate of 2, 3 and 5 year was 70. 6%, 64. 2 % and 50% respectively. Conclusion: It is key that neck dissection should be performed rightly and the principle of surgery should be carried out for successful Pearson operation.
