喉额侧窗式切除术治疗侵及前联合的T1b期声门型喉癌疗效分析

摘要

Objective To explore the efficacy of reserving thyroid cartilage combined with thyroid perichondrium flap to repair the defect of frontal-lateral window partial laryngectomy for T1b glottic cancinoma with anterior commissure involved.Methods From our hospital 22 cases diagnosed as T1b glottic cancer with anterior commissure invaded were treated with frontal-lateral window partial laryngectomy and were repaired by reserving thyroid cartilage combined with flap of thyroid perichondrium.All the patients were followed up for five years.The functions of respiratory and swallowing,voice rehabilitation,ratios of recurrence and survival were observed.Results All the patients succeeded in removing tracheal cannula.The decannulation rate was100％ and the aspiration rate was 0％.The voice functions in patients with postoperative classification (G) were higher than that of preoperative accounted for 86.4％ (19/22),and the same preoperative accounted for 13.6％ (3/22).There were 2 cases with tumor recurrence,one cases with recurrence in situ and one case with cervical lymph node metastasis.The recurrence rate was 9.1％ (2/22) and the 5 year survival rate was 95.5％ (21/22).Conclusion Frontal-lateral window partial laryngectomy reserving thyroid cartilage combined with thyroid perichondrium flap,is suitable for T1b glottic cancinoma invading anterior commissure.It can preserve the laryngeal framework and function relatively integrated with rare laryngeal stenosis and stabble repaired tissue.It also can effectively improve the sound quality and is worthy of clinical promotion.%目的 探讨喉额侧窗式切除术结合甲状软骨外膜瓣修复术治疗侵及前联合的T1b期声门型喉癌的疗效.方法 对确诊为前联合受侵的T1b期声门型喉癌患者22例,均行喉额侧窗式切除术结合甲状软骨外膜瓣修复术治疗;随访5年,观察患者术后呼吸功能、吞咽功能、发音功能、复发率及生存率.结果 所有患者手术均顺利完成,术后二周拔除气管套管,拔管率100％;无一例发生误咽;术后患者发声功能(G分级)较术前改善者为86.4％(19/22),与术前相同者为13.6％(3/22);肿瘤复发2例,1例为原位复发,1例为颈部淋巴结转移复发,复发率为9.1％(2/22);5年生存率为95.5％(21/22).结论 喉额侧窗式切除术结合甲状软骨外膜瓣修复术式适用于前联合受侵的T1b期声门型喉癌,该术式能相对完整地保留喉的骨架及生理功能,不易引起喉狭窄,且修复组织稳定,能有效改善发声质量.
