Abstract

Chronic recurrent TMJ dislocation results in difficulty of mastication, speaking, and swallowing due to the limitation of the mandibular movement. Etiologic factors are considered as the looseness of the capsule and ligaments, the decrease of the articular eminence, condylar morphologic change, muscular disharmony near by TMJ, and the decrease of the vertical length of the mandibular ramus. Treatment approach has been suggested that surgical methods are selected for the correction of the etiologic factors when conservative treatments are not effective. Many surgical methods have been reported such as eminectomy, eminence augmentation, condylotomy, and zygomatic arch down fracture technique. We performed the eminence augmentation through interpositional bone graft in chronic recurrent TMJ dislocation. This method leads to favorable postoperative result without recurrence and complication, so we report the case with related references.
