title: [Application of harmonic scalpel in Han-uvalopalatopharyngoplasty].
abstract: OBJECTIVE
  To investigate the efficacy and feasibility of harmonic scalpel assisted Han-uvalopalatoparyngoplasty (H-UPPP) for obstructive sleep apnea and hyponea syndrome (OSAHS).
  
  
  METHODS
  For each case of 23 patients with OSAHS, the left was operated on with traditional method and the right was operated on with harmonic scalpel. Operative blood loss, the operation time, postoperative pain, the condition of wounds and complications were compared for each case itself.
  
  
  RESULTS
  The operative blood loss, the operation time, of the right with harmonic scalpel were much less than the left with traditional method,while no difference in postoperative pain, incidence of primary and secondary hemorrhage, the condition of wounds was found.
  
  
  CONCLUSIONS
  The application of harmonic scalpel in H-UPPP was safe, efficient and feasible, and would have a nice application prospect during otolaryngology operations.
