Chronic recurrent temporomandibular joint (TMJ) dislocation is defined as the complete loss of articular relationships, during mouth-wide opening, between the articular fossa of the temporal bone and the condyle-disk complex. The most frequent pathogenetic factors involved in chronic recurrent dislocation of the TMJ are supposed to be trauma, abnormal chewing movements, TMJ ligaments, capsule laxity, and masticatory muscles disorders. In fact, TMJ dislocation occurs more frequently in people with general joint laxity and in patients with internal derangement of the TMJ or with occlusal disturbance. Management of TMJ dislocation remains a challenge. Eminectomy, whose validity has been demonstrated by several authors, acts on the bony obstacle, preventing condylar locking, but does not have a therapeutic effect on TMJ ligament and capsular laxity or masticatory muscle incoordination, which seem to be the real cause of TMJ dislocation in most cases. The authors present a mini-invasive modified technique of eminectomy, which aims to act on both the obstacle and the cause with respect and restoration of TMJ biomechanical constraints.
