目的：探讨声门癌Ｔ３病变在喉大部切除后重建喉支架的手术方法。方法：３６例声门癌Ｔ３病变，在喉大部切除后施行改良会厌喉成形术：①一侧甲状软骨全切除，会厌软骨侧向下移取代；②对侧甲状软骨部分保留，肌筋膜瓣或肌甲状软骨膜瓣修复声带；③会厌前侧缘与甲状软骨前缘对合成锐角前连合，后侧缘与对侧杓部形成后连合，会厌上缘与对侧声带形成新声门。结果：３３例拔管，３０例发声清晰、宏亮且易懂，３例发声低沉沙哑。３年和５年的生存率分别为８９．３％和７７．３％，喉功能稳定率分别为９５．６％和９４．１％。结论：改良会厌喉成形术是治疗声门癌Ｔ３病变有效的手术方法
Objective: To investigate the surgical method of reconstructing laryngeal scaffold after glottic excision of T3 glottic cancer. Methods: Thirty-six patients with T3 glottic cancer were treated with modified epiglottis laryngectomy after partial laryngectomy: (1) thyroid cartilage was excised on one side and replaced laterally by epiglottic cartilage; (2) the contralateral thyroid cartilage was partially preserved and myofascial Flap or muscle cartilage flap repair vocal cords; epiglottis anterior margin and thyroid cartilage front an acute anterior commissure, the posterior margin and the contralateral ladle after the formation of commissure, the epiglottis edge and the contralateral vocal cord to form a new sound door. Results: 33 cases of extubation, 30 cases of clear voice, bright and easy to understand, 3 cases of low-sounding hoarseness. The 3-year and 5-year survival rates were 89.3% and 77.3%, respectively. The stability rates of laryngeal function were 95.6% and 94.1% respectively. Conclusion: Modified epiglottic laryngeal plasty is an effective surgical treatment of T3 glottic cancer
