title: [A preliminary study of surgical treatment for disc displacement of temporomandibular joint].
abstract: OBJECTIVE
  To preliminarily evaluate the surgical treatment results of disc displacement of temporomandibular joint(TMJ).
  
  
  METHODS
  From October 2009 to September 2010, 9 patients (11 joints) with disc displacement of TMJ ( 8 females and 1 male, and with an average mouth opening of 21.3mm) underwent disc repositioning and fixation via arthroscopy or open anchorage surgery. All patients were clinically followed up at least 3 months, and MRI examinations were performed at regular intervals.
  
  
  RESULTS
  All incisions healed well and there were no severe complications. The average mouth opening increased to 32.8mm and the disc position remained favorable on MRI at the latest follow-up.
  
  
  CONCLUSIONS
  With accurate diagnosis and selection of appropriate indications, disc repositioning and fixation via arthroscopy or open anchorage surgery should be used as a treatment of choice for disc displacement of TMJ.
