title: [The application of decompression in the treatment of gnathous cystic lesions].
abstract: OBJECTIVE
  To explore the application of decompression in the treatment of ganthous cystic lesions.
  
  
  METHODS
  Decompression surgery were performed on 32 patients with gnathous cystic lesions, the cavities of cysts were open and the cysts pressure was relieved. The cavities of cysts were flushed after the operation and the prognosis were assessed in the regular follow-up.
  
  
  RESULTS
  All cysts cavities were shrinks afer decompression operation. Through the X-line and/or CT scans, we could observe that the new bones formed around cysts cavities, tilt shift teeth were gradually corrected and the permanent tooth germs of pediatric patients almost returned to the right places and erupted; There were the only remaining small bone indentations in the 18 cases, which do not need the Phase II surgery. Eight cases of cysts cavities shrinks more than 50%, which needed cystectomy. Six cases of cysts cavities shrinks less than 50%, which were still in the follow-up treatment.
  
  
  CONCLUSIONS
  The decompression surgery is a simple, economical and effective method for the treatment of gnathous cystic lesions.
