[Chronic temporomandibular joint luxation. Results after corrective surgery]

Recidivating luxation of the TMJ are the topic. The clinical picture, therapy and operative methods are described. In particular, the results from a modified intraoral surgical operation are reported. Special emphasis is placed upon the partial removal of the medial pterygoid muscle which leads to a stronger and permanent scarring. This method is particularly suited for recidivating luxations, when the condyle paths are steep, and when luxation occurs toward the end of the mandibular opening movement. When condyle paths are flat or in cases of recidives other methods are recommended (for instance osteoplasty).
