title: [Clinical significance of preoperative tracheotomy in preventing perioperative OSAHS severe complications].
abstract: OBJECTIVE
  Studying the value of preoperative tracheotomy in preventing obstructive sleep apnea-hypopnea syndrome (OSAHS) severe complications in preoperative and postoperative period of UPPP/PPP and the its significance in ensuring the safety of surgical operation.
  
  
  METHODS
  One hundred and four OSAHS severe cases were retrospective analysed from July 1998 to July 2003, and these cases were divided into tracheotomy group and non-tracheotomy group. Preoperative and postoperative complications of these cases were studied.
  
  
  RESULTS
  The incidence of complications especially severe complications endangering life in tracheotomy group was lower significantly than in non-tracheotomy group.
  
  
  CONCLUSIONS
  It is very necessary to do tracheotomy preoperatively so as to preventing severe complications of OSAHS and ensuring the safety of surgical operation.
