Objective To determine the role of transoral CO2 laser resection in laryngeal carcinomas. Methods The clinical data of 12 patients with early laryngeal tumors, whose pathological results showed glottic and supraglottic squamous cancer during July 2010 to August 2011, were retrospectively analyzed. After ascertaining tbe extent of the tumor with self-retaining laryngoscope, a C02 laser machine was connected to the microscope by a coupler to remove the tumor. Results The operation time ranged from 14 to 33 minutes with a mean of 18. 7 minutes. All the patients had normal diet on the day after the operation, and then were discharged from hospital in three days. The patients were followed up for 6 to 18 months with a mean of 13.4 months. One of them had local recurrence in 8 months, one patients showed metastasis to the neck lymph nodes in 10 months, one patient developed expiratory dyspnea because of inflammatory granuloma, and two patients showed vocal cords adhesion at the anterior commissure. Conclusion As the first choice for T1/T2 glottic and supraglottic carcinoma, transoral CO, laser can excise tumor correctly with the larynx being preserved, without needing tracheotomy or nasal feeding. It shortens hospital stays and reduces complications.%目的 探讨CO2激光治疗喉肿瘤的效果. 方法 2010年7月～2011年8月对12例早期声门型及声门上型喉鳞状细胞癌,在支撑喉镜下明确病变范围,CO2激光机通过耦合器连接于显微镜,行CO2激光肿瘤切除术. 结果 手术时间14～33 min,平均18.7 min.术后当日进食.术后3d内出院.12例随访6～18个月,平均13.4月,术后8个月局部复发1例,术后10个月颈部淋巴结转移1例,声带炎性肉芽肿致呼吸困难1例,声带粘连2例. 结论 CO2激光治疗T1、T2期声门型及声门上型喉癌能确切切除肿瘤和保留喉功能,无须气管切开和鼻饲,住院时间短,并发症少.
