title: [Long term follow up of laser surgery under micro-endoscopy for laryngeal carcinoma].
abstract: OBJECTIVE
  To observe the long term curative effect for laryngeal carcinoma treated with CO2 laser under micro-endoscopy.
  
  
  METHODS
  Twenty cases of laryngeal cancer were treated by CO2 laser under micro-endoscopy. All patients were followed up at least 5 (5-8) years by phone, letters or clinical review.
  
  
  RESULTS
  During 5 to 8 years following up, one patient died of recurrence 1 year later. Another was operated on with partial laryngectomy due to local recurrence 2 years after laser surgery. The third one was operated with selective neck dissection because of neck metastasis 5 years later. Other 17 cases were alive without recurrent signs. The 5 years total cure rate was 85% and survival rate was 95%, the 5 years local recurrence rate was 10% and the neck metastasis rate was 5%. All survivals had normal breath and good phonation. Among them 8 resumed their daily works, 5 were used to do house works and 4 did them sometimes.
  
  
  CONCLUSIONS
  T1 and earlier glottic or supraglottic cancers are indications of laser surgery under micro-endoscopy. Its 5 years survival rate as well as live quality were satisfactory and proved the method to be a choice of treatment for earlier laryngeal carcinoma.
