目的　研究保留喉舌功能的口咽舌会厌区癌切除术的手术方法及疗效。方法　对1990～ 2 0 0 0年经治的 2 1例口咽舌会厌区癌进行回顾性临床研究 ,其中男 17例 ,女 4例 ;按 1992年UICC临床分期 ,T2N0 4例 ,T2N15例 ,T3N112例。 2 1例均行部分舌根及喉水平部分切除术。 17例行分区性颈清扫术。术后全部接受 5 0～ 6 0Gy放射治疗。结果　 2 0例拔除气管套管 ,完全保留喉舌功能 (95 2 % ) ,1例不能拔管保留了言语功能和吞咽保护功能 (4 8% )。 3年生存率 73 3% (11/15 ) ,5年生存率 5 7 1% (8/14)。结论　经舌骨下入路保留喉舌功能的口咽舌会厌区癌切除术是有效可行的 Objective To study the surgical methods and curative effect of cancerous resection of the oropharyngeal tongue in patients with mouth-opening. Methods A retrospective clinical study was performed on 21 cases of cancer of the epiglottis area between 1990 and 2000. There were 17 males and 4 females. According to the clinical stage of UICC in 1992, there were 4 cases of T2N0, 15 cases of T2N, T3N112 cases. 21 cases of partial tongue and throat horizontal partial resection. 17 cases of regional neck dissection. All patients received 50 Gy to 60 Gy after radiotherapy. Results Twenty cases of tracheal cannula were removed, the function of mouthpiece was completely preserved (95 2%). One case of extubation could not retain the speech function and swallowing protection function (48%). 3-year survival rate 73 3% (11/15), 5-year survival rate 5 7 1% (8/14). Conclusions The oropharyngeal epiglottis carcinoma resection with preserving mouthpiece function is feasible and effective
