[Preservation of laryngeal function in treatment of pyriform sinus carcinoma].

OBJECTIVE

To study the treatment outcome of laryngeal function sparing of pharyngectomy in pyriform sinus carcinoma.

METHOD: Fourty-two cases with pyriform sinus cancer in laryngeal function sparing surgery were collected from 1989 to 1999. The method of operation, the complication and surviving rate were analyzed.

RESULT: The decannulation rate was 61.9% (26/42) . The rate of complication was 31.0% (13/42), the 3 years and 5 years' survival rates were 76.1% and 66.6% respectively.
