[Extra-articular rearrangement of temporomandibular joint internal derangement and associated neuromuscular disorders].
This report introduces a new method for treatment of TMJ internal derangements and associated neuromuscular disorders. This operation consists of two main surgical procedures: (1) To detach the muscular attachments of masseter, temporal, and internal pterygoid muscle from the mandible and to detach the external pterygoid muscle from the external pterygoic plate for eliminating the neuromuscular disorders. (2) To reposition the condylar head from the glenoid fossa after making a vertical osteotomy on the posterior portion of the ramus for eliminating the internal derangements of the joint. Therefore, the causes of considerable embarrassment of TMJDS could be eliminated and the iatrogenic trauma to the joint could be avoided. Since 1987-1990, 15 cases have been successfully performed.
