Among the numerous causes of facial neuralgias, the painful dysfunction syndrome of the manducatory apparatus corresponds to a frequent etiology whose thorough study carried out by a multidisciplinary team over about 500 cases allowed their splitting into several evolutive clinical forms. At present, a number of these forms which are particularly painful, require a disk surgery (dislocation reduction, perforation suture, etc.) and if necessary an articular facet surgery (modelling condylectomy, surfacing, etc.). This study specifies the indications and prognosis for these surgical operations.
