title: [Clinical characteristics of different cordectomy types with potassium titanium phosphate laser].
abstract: OBJECTIVE
  To study the clinical characteristics of different potassium titanium phosphate(KTP) laser types and surgical the recuperating course of cordectomy under suspension laryngoscope.
  
  
  METHODS
  Follow-up observation were applied on 76 patients with cordectomy. Restoration of laryngeal structure and change of the quality of voice were observed and recorded.
  
  
  RESULTS
  Type 1, normal laryngeal structure and function were restored postoperatively after 3 months; Type 2, a fold like vocal cord (new vocal cord) appeared 3 months later. Laryngeal structure was basically restored; Type 3, a mucosal fold appeared postoperatively after 6 months in most patients, but it lost motion function. Recurrence time was mainly found 2-4 months. Recurrence rate was 6.7%. Two and 5-year survival rate were 100%.
  
  
  CONCLUSIONS
  Cordectomy with KTP laser can result in good effect and less injury. Type 2, 3 can retain thyroarytenoid muscle as much as possible on the basis of radical cure.
