环状软骨上喉部分切除术及其疗效

目的探讨环状软骨上喉部分切除并重建新喉的术式及其疗效。方法回顾分析1993年5月～2000年5月间行环上喉部分切除并作舌骨-会厌、环状软骨融合术的住院病例共22例，均男性，年龄43～74岁，平均63岁。按1997年UICC喉癌TNM分类，21例声门型，其中T1aNoMo 3例，T1bNoMo 4例，T2NoMo 11例，T3NoMo 3例，声门上型T2N1Mo 1例。结果 3年和5年生存率分别为88.24％和70％。所有患者术后M～60d拔除气管套管，平均25d，拔管率100％。术后有较好的发音功能。结论本术式操作简便，易于掌握，切除肿瘤的同时可以保留喉的生理功能，值得推广应用。

Supracricoid Partial Larynegectomy for Laryngeal Cancer

Objective To assess the effectiveness of supracricoid partial laryngectomy in the treatment of laryngeal cancer. Methods This study infiuded 22 patients operated on from 1993 to 2000 using this surgical procedure. 22 were males with mean age of 63 years (ranging from 43 to 74 years). 21 were glottic cancers (3 T1aNoMo, 4 T1bNoMo, 11 T2NoMo, 3 T3NoMo) and 1 supraglottic cancer (T2N1Mo) according to the 1997 UICC system. Supracrieoid partial laryngectomy was performed, with the epiglottis preserved and reconstructed with cricohyoidoepiglottopexy (CHEP). Results The overall 3-year and S-year survival rates were 88.24％ and 70％, respectively. All patients were decannulated. The average time for decannulation was 25 days (ranging from 14 to 60 days). Speech was good in all cases. Conclusion CHEP not only excises the neoplasms completely and safely but also preserves the laryngeal physiologic function well.
