为进一步探讨显微喉镜下 Ｃ Ｏ２ 激光手术治疗喉癌的适应证、禁忌症、手术方法、注意事项及手术效果，对 ２０ 例喉癌患者在支撑喉镜下行 Ｃ Ｏ２ 激光显微手术，其中会厌癌 １ 例（ Ｔ１ Ｎ０ Ｍ ０），声门癌 １９ 例（ Ｔｉｓ ２ 例、 Ｔ１ Ｎ０ Ｍ ０ １６ 例、 Ｔ３ Ｎ０ Ｍ ０ １ 例）。５ 例行气管切开，１ 例行术前放疗，３ 例行术后放疗，术后患者恢复良好。平均住院时间 ２０３５±５．３９ｄ，较常规手术 ３０６±７３４ｄ 明显缩短（ Ｐ＜ ０．００１），无严重手术并发症发生。术后随访１３ 个月～４．５ 年，１ 例死于局部复发，１９ 例健在。术后发音好于常规手术。提示 Ｔ１ 声门区和声门上区喉癌适合显微喉镜 Ｃ Ｏ２ 激光手术，但 Ｔ２ 以上的喉癌不宜选用该手术。
To further investigate the indications, contraindications, surgical methods, precautions, and operative effects of microscopic laryngoscopic C O2 laser surgery for laryngeal carcinoma, C O2 laser microsurgery was performed on support laryngoscope in 20 patients with laryngeal cancer. One case of epiglottis cancer (T1 N0 M0) and 19 cases of glottic cancer (2 cases of Tis, 1 case of T1 N0 M0, and 1 case of T3 N0 M0). 5 routine tracheotomy, 1 routine preoperative radiotherapy, 3 routine postoperative radiotherapy, postoperative patients recovered well. The average length of stay was 2035±5.39d, which was significantly shorter than that of conventional surgery 306±734d (P<0.001). No serious complications occurred. During the follow-up period of 13 months to 4.5 years, 1 patient died of local recurrence and 19 patients were alive. Postoperative pronunciation is better than conventional surgery. Tip T1 glottic and supraglottic laryngeal cancer is suitable for microscopic laryngoscope CO2 laser surgery, but laryngeal cancer above T2 should not be used.
