[Preservation of laryngeal function in surgical treatment of T3 supraglottic laryngeal carcinoma].

Abstract

Objective: To explore the feasibility,surgical techniques and the clinical curative effect of preservation of laryngeal function in surgical treatment of T3 supraglottic laryngeal carcinoma (SLC).

Method: A retrospective review of 70 cases with T3 SLC that we treated from 1994 to 2003 were accomplished. All of the cases were treated with partial laryngectomy. Among them, 42 cases underwent supraglottic horizontal partial laryngectomy, 19 supraglottic horizontovertical laryngectomy, 8 supracricoid partial laryngectomy and 1 near total laryngectomy. All patients were received postoperation radiotherapy with the dosage for 50-60 Gy.

Result: The 3 year and 5 year-survival rates were 79.2% and 68.4%, respectively. Out of the 70 cases, 60 cases were decannulated with a decannulation rate of 85.7%. The normal diet was resumed in all patients, no buckling and dysphagia obviously. All patients had their successful phonation, no one failure for laryngotracheal atresia.

Conclusion: It is feasibility to preservative laryngeal function in surgical treatment of T3 SLC, if surgeons master indications correctly, use many kinds restorative procedure expertly and improve surgical skill.
