title: [Complications of orthognathic surgery. Apropos of a series of 84 patients].
abstract: BACKGROUND
  Patients demand satisfactory functional and esthetic results from orthognatic surgery. The aim of this study as to assess adverse outcomes after orthognatic surgery.
  
  
  METHODS
  We retrospectively reviewed 84 patients who underwent maxillary (22.6%), mandibular (29.8%) or bimaxillary (38.1%) osteotomy in 1997. We re-examined 76 of these patients at a mean 21 months follow-up. Data were recorded for the preoperative, early postoperative, secondary postoperative and late postoperative periods.
  
  
  RESULTS
  Infectious complications occurred in 2% of the cases of maxillary surgery. For mandibular surgery there were 10.5% infectious complications including 83% that resolved spontaneously, 3.5% neurological complications and 1.7% temporomandibular joint complications.
  
  
  CONCLUSIONS
  Maxillary osteotomy has proven reliable. Major adverse outcome is infrequent but serious. Adverse outcomes in mandibular surgery are more common but less problematic.
