[Applied study of voice function rehabilitation by mucosa tube performed in operation of late laryngocarcinoma.].

OBJECTIVE

To study the voice function rehabilitation by mucosa tube performed in operation of late laryngocarcinoma and to improve the survival quality of patients with late laryngocarcinoma.

METHODS

Forty-six patients were treated between Oct. 1991 and May 2006, including 41 males and 5 females. The average age of the patients was 54. Seventeen cases were glottic carcinomas (T3N0M0 12, T3N1M0 5), 27 cases were supraglottic carcinomas (T3N1M0 16, T4N1M0 5, T3N0M0 6), 2 cases were pyriform sinus cancer (T4N1M0 2). For those patients with late laryngocarcinoma, who had lost the chance of partial laryngectomy, mucosa tube shaping during the operation could realize voice functional rehabilitation. Only the survive arytenoids of healthy side was preserved, in order to rehabilitate voice, a mucosa tube was sutured using healthy survive arytenoids and a mucosa strip was connected to the trachea and the mucosa of hypopharynx. Survival analysis was performed by using Kaplan-Meier method.

RESULTS

Forty-one out of 46 patients obtained almost normal voice and swallow function. The 5-years survival was 76%.

CONCLUSIONS

The operation of voice function rehabilitation by mucosa tube performed can get good voice and swallow function to patients with late laryngo carcinoma.
