title: [Clinical observation of 173 cases of partial laryngectomy].
abstract: OBJECTIVE
  To summarize and study the clinical effect of partial laryngectomy on laryngeal neoplasms.
  
  
  METHODS
  173 cases of partial laryngectomy were performed. 6 kinds of operations were performed, 49 vertical laryngectomy, 39 supraglottic laryngectomy, 4 frontolateral laryngectomy, 47 extended partial laryngectomy ( with reservation of epiglottis and posterior part of thyroid cartilage), 17 pearson's surgery, 17 near-total laryngectomy with cricoglossal anastomosis.
  
  
  RESULTS
  168 cases restored their phonation, 145 cases were decannulated in three months after operations. The survival rates of three and five year was 79.77% and 69. 94%, the local relapsing rate was 18.50%.
  
  
  CONCLUSIONS
  Successful partial laryngectomy based on strict indications and correct operation choices. While the laryngeal function was reconstructed, it is necessary to restore the phonation, sphincter and respiratory function.
