ABSTRACT
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.
