目的:探讨内镜CO2激光声带切除治疗T1声门癌时阴性声带切除的发生率及原因。方法:回顾性分析海军总医院2000-01-2010-02内镜CO2激光治疗的57例T1声门型喉癌患者的临床资料和病理资料。采取术前钳取活检和术中冷冻切片病理学检查。结果:声带切除Ⅰ型5例、Ⅱ型4例、Ⅲ型41例、Ⅳ型3例和Ⅴa型4例。术后标本阴性6例。阴性声带切除发生率为10.5%。结论:CO2激光声带切除时,应在保证切缘安全情况下,尽可能减少声带组织的切除。
Objective: To investigate the incidence and causes of negative vocal cords during endoscopic CO2 laser vocal cord excision for T1 glottic cancer. Methods: The clinical data and pathological data of 57 cases of T1 glottic laryngeal carcinoma treated with endoscopic CO2 laser in Navy General Hospital from January 2000 to October 2010 were retrospectively analyzed. Preoperative biopsy and intraoperative frozen section biopsy were used. Results: There were 5 cases of type Ⅰ, 4 cases of type Ⅱ, 41 cases of type Ⅲ, 3 cases of type Ⅳ and 4 cases of type Ⅴa. Six cases were negative after operation. Negative vocal cord excision was 10.5%. Conclusion: CO2 laser vocal cord resection should be cut margin as much as possible to ensure the safety margin.
