title: [Preventive study of vocal scar after fiber laryngoscope surgery].
abstract: OBJECTIVE
  To explore the importance and preventive measure of vocal scar after fiber laryngoscope surgery.
  
  
  METHODS
  The preventive measures such as treatment of the pathogeny, voice exercise, adjustment of operative skill, vocal rest after operation and drug treatment for vocal scars in 350 patients with polyps of vocal cord, vocal nodules and vocal cyst after fiber laryngoscope surgery were adopted in order to reduce the rate of vocal scar. The rate of vocal scar was calculated and analysed to evaluate the effect of preventive measures two month later.
  
  
  RESULTS
  The incidence rate of vocal scar after fiber laryngoscope surgery was 12.3%. And vocal scar was the main difficulty in vocalizing after operation. There is yet no specific treatment for vocal scar. Prevention is more important. Preventive measures should be carried out through the perioperative period, i. e., before, in and after the surgery.
  
  
  CONCLUSIONS
  The prevention of vocal scar complication is very important in the perioperative period of fiber laryngoscope surgery. And as the preventive measures are adopted, the incidence rate of vocal scar will be significantly reduced.
