title: [Phonation reconstruction and function assessment after total and near-total laryngectomy].
abstract: OBJECTIVE
  Total laryngectomy is a common surgery pattern for treating laryngeal and hypopharyngeal cancer, but patients will lost phonation function after operation. This study was to retrospectively analyze usage of modified Amatsu, and modified Pearson operation in treating laryngeal and hypopharyngeal cancers, and to analyze phonation function by subjective and objective assessment.
  
  
  METHODS
  Clinical data of 69 patients with laryngeal or hypopharyngeal cancer treated by total or near-total laryngectomy (modified Amatsu or modified Pearson operation) in our department from 1996 to 2003 were retrospectively analyzed. Phonation function of 69 patients was evaluated by acoustic analysis and Jiyan classification method, and compared with phonation quality of patients received vertical hemilaryngectomy (VHL) and healthy people.
  
  
  RESULTS
  No patient appeared obvious aspiration. Four cases with post-operative radiotherapy all regained phonation function. The 3-year survival rate was 88% (22/25); 5-year survival rate was 80% (4/5). Results of acoustic assessment, and Jiyan classification method indicated that phonation function of patients received modified Amatsu or modified Pearson operation could meet daily requirements.
  
  
  CONCLUSIONS
  Modified Amatsu and modified Pearson operations can be learnt and applied easily for phonation reconstruction after laryngectomy. They may be optional surgery patterns, especially modified Pearson operation.
