[A preliminary study on the clinical application of temporomandibular joint arthroscopy]

The temporomandibular joint arthroscopy was performed on 24 joints of 18 patients. The procedure was carried out under local anaesthesia by inferiolateral approach. Main changes of upper compartments were showed on the bilaminar zone, including disc perforation and anterior displacement and capsular loosening. The abnormal discoveries of lower compartments were mainly erosion of the condylar cartilage. The indications and techniques of arthroscopy of TMJ were discussed and described.
