title: [Window partial laryngectomy with endoscopy for the treatment of stage T1b--T3 laryngeal carcinoma].
abstract: OBJECTIVE
  To investigate the operative effect and value of window partial laryngectomy with endoscopy for treatment of stage T1b--T3 laryngeal cancer.
  
  
  METHODS
  Twenty-seven cases with glottic laryngeal cancer were treated by window partial laryngectomy with endoscopy. After 3-year and 5-year survival rate and laryngeal functions (respiratory, pronunciation, swallowing function) recovery were evaluated.
  
  
  RESULTS
  The 3- and 5-year survival rates were 83.3% (15/18) and 75.0% (9/12) respectively. The decannulation rate was 92.6% (25/27) 4 weeks after operation. Three months after decannulation of respiratory function evaluation: the march to fast runner 77.8% (21/27), the jogger 14.8 (4/27), who walk briskly 7.4% (2/27). All patients had recovered after four weeks swallowing without choking cough and satisfied with phonation. Local recurrence rates at 3 and 5 year after operation were 10.5% (2/19) and 15.4% (2/13) respectively.
  
  
  CONCLUSIONS
  The research shows that window partial laryngectomy with endoscopy was applicable to stage T1b--T2 and selecting T3 laryngeal cancer patients. Postoperative respiratory, pronunciation and swallowing function recovery rate is satisfactory.
