SURGICAL CORRECTION OF RECURRENT HABITUAL TEMPOROMANDIBULAR JOINT DISLOCATION

Unilateral or bilateral displacement of the mandibular condyle anteriorly and superiorly from the articular eminence is called temporomandibular joint dislocation. Mostly, it can be treated with non-surgical conservative methods, but if dislocation occurs as chronic, or recurrent protracted condition, surgery may be indicated. Various surgical procedures has been used for limitation of condylar movement by soft tissue tethering and artificial creation of obstacles, or removal of mechanical blockade, and procedure for augmentation of articular eminence using different kinds of grafts. In our case of 57-years old man as diagnosed as recurrent habitual temporomandibular joint dislocation, we treated this patient with miniplate augmentation on front of articular eminence for limitation of condylar hypermobility with dislocation, postoperative results are good without functional limitation or occurrence of dislocation.
