abstract: OBJECTIVE
  To evaluate the application of bi-pedicel and bi-muscle flaps for the expanded partial laryngectomy in the patients with T3T4 larynx cancer.
  
  
  METHODS
  From 1990 to 1997, 386 patients of laryngeal cancer were treated by expanded partial laryngectomy and repaired with unilateral or bilateral bi-pedicel and bi-muscle flaps. 322 patients were male and 64 were female. The age ranged from 30 to 84 years old. All the patients were in the stage T3 or T4 of cancer. The operation included expanded horizontal supraglottic laryngectomy, vertical partial laryngectomy, 3/4 laryngectomy and sub-total laryngectomy.
  
  
  RESULTS
  After operation, the speech function was still good in all cases. The swallow function recovered in 8 to 12 days post-operation. The extraction rate of tracheal tube was 50.3% (194/386), and the 5-years survival rate was 55.2% (213/386) while the local recurrence rate was 16.6% (64/386).
  
  
  CONCLUSIONS
  With the application of bi-pedicel and bi-muscle flaps, the patients, if treated by total laryngectomy as traditional technique, could be treated by partial laryngectomy. This method could expand the indication of partial laryngectomy and improve the life quality and survival rate.
