title: [The application of extended supraglottic horizontal partial laryngectomy in advanced laryngeal carcinoma and vallecula carcinoma].
abstract: OBJECTIVE
  To discuss the function recovery and treatment effect of extended supraglottic orizontal-partial laryngectomy in the treatment of advanced laryngeal carcinoma and vallecula carcinoma.
  
  
  METHODS
  Forty-four patients who received extended supraglottic orizontal partial laryngectomy were followed up on the survival, breath function, pronunciation and swallowing function.
  
  
  RESULTS
  The 2-year, 3-year survival rates of this group were 72.7% and 71.4%, respectively. There were no recurrence cases in this group. All cases of death were due to cervical lymph node metastasis or recurrent cervical lymph node metastasis after cervical lymph node dissection. The extractive rate of tracheostomy tube was 97.7%. Forty-two patients own good pronunciations. Two patients who received partial arytenoid cartilage resection own weaker pronunciations. After practising, all the patients can eat without the nasal feeding tube.
  
  
  CONCLUSIONS
  Extended supraglottic orizontalpartial laryngectomy give complete resection of the primary lesion. Patients who received extended supraglottic orizontalpartial laryngectomy have good breath, swallowing and pronunciation function.
