title: [Clinical study on treatment of early glottic carcinoma with different cordectomy].
abstract: OBJECTIVE
  To explore the advantage of KTP laser cordectomy in the treatment of early glottic carcinoma.
  
  
  METHODS
  Follow-up observation on 30 patients who had KTP laser cordectomy and 18 patients who had laryneal split cordectomy was applied, then their postoperative laryngeal structure's change, the quality of voice and the quality of life (QOL) were compared and analyzed.
  
  
  RESULTS
  The patient group treated by KTP laser grew out a piece of new cord just at the place where it was excised after half a year, and the quality of voice was obviously improved near to norm, and they had higher QOL. On the contrary, the other group had no newly grown cord, their quality of voice was better in the first half year but was worse last out. Their QOL was lower than the laser group before decannulation and the same as the laser group after the decannulation. There are 2 cases recurrented in the laser group and 1 case recurrented in the laryneal split group, the two groups all had no metastasis and death in laryneal carcinoma by 2-4 years follow up postoperation.
  
  
  CONCLUSIONS
  On the basis of effecting radical cure, the early glottic carcinoma treated with non-contact KTP laser with suspension laryngoscope can result in good recuperating in laryngeal structure, less injury and high QOL. So it makes micro-injury treatment in laryngeal carcinoma come true and better than the laryngeal split cordectomy.
