[Bi-pedical and bi-muscle flap reconstruction of the laryngeal function].

The method of reconstruction of laryngeal function by bi-pedical and bi-muscle flap (DP-DMF) was presented. The DP-DMF was obtained from sternohyoid muscle, sternothyroid muscle and thyrohyoid muscle. It had enough length, width and plasticity, applicable to all patients with T3 and T4 laryngeal carcinoma. Up to now, 102 patients were treated by expanded horizontal hemilaryngectomy and repaired with unilateral or bilateral DP-DMF. After operation, the swallow function returned to normal in 7 to 11 days. The tracheal tube extraction rate was 66.7% (72/108). The 5-year survival rate was 76.5% (62/81), and recurrence rate was 13.9% (15/108). With the application of DP-DMF, the patients who might have been treated formerly by total laryngectomy could be treated by partial laryngectomy. This method expanded the indication of partial laryngectomy, improved the life quality and survival rate.
