Use of bone plates and screws to manage chronic mandibular dislocation

subject

description

Different treatment modalities are described in literature to treat mandibular recurrent dislocation, including intra- capsular esclerosant injections, articular eminence reduction, soft tissues suture to limit condilar movement, and grafts or implants to create mechanical interference, like zygomatic arch down fracture or articular eminence in- crease by bone plates. In this paper, a patient with mandibular recurrent dislocation episodes were eliminated after bilateral fixation of bone plates to the lateral sur-face of the zygomatic arch to restrict mandibular movements. One arm of the plate was extended me-dially just below the articular eminence and fixed at lateral zygomatic arch portion by two screws. The surgical technique is described and 24 months follow-up period is demonstrate with excellent recovery and functional activities. The temporomandibular joint (TMJ) function was unimpeded and no recu-rrence of condilar dislocation was observed. We concluded that this technique is safe and efficient to hinder dislocations of mandible, preserve the TMJ initial characteristics, and prevent abnormal condi-lar movements over the eminence
