探讨应用保留杓状软骨的喉次全切除喉功能重建术治疗Ｔ３喉癌的拔管率和３、５年生存率。方法对２０例Ｔ３级喉癌，其中声门型３例，声门上型１７例，根据病变范围行保留单侧或双侧杓状软骨喉次全切除及功能重建术，并设计环咽吻合术式。

The reconstruction of laryngeal function in subtotal laryngectomy with preservation of arytenoid cartilage]

OBJECTIVE: To evaluate subtotal laryngectomy with preservation of arytenoid cartilage to reconstruct laryngeal function in T3 glottic or supraglottic laryngeal cancer. METHODS: Subtotal laryngectomy with preservation of arytenoid cartilage to reconstruct laryngeal function was reviewed in 20 patients with T3 laryngeal cancer(3 cases with glottic cancer and 17 cases with supraglottic cancer). Recurrent laryngeal nerve was preserved during surgery. The mucous membranes between cricoid cartilage and pharynx were sewed up accordingly. RESULTS: All patients had restored phonation and swallowing functions. The 3- and 5-year survival rates were 94.1% and 91.8% respectively. Decannulation rate was 95.0%. CONCLUSION: Subtotal laryngectomy with preservation of arytenoid cartilage is recommended for T3 laryngeal cancer.
