Abstract

A case of prolonged unilateral temporomandibular joint (TMJ) dislocation, which was treated by open surgical reduction and post-surgical orthodontic therapy, is presented. A 58-year-old woman presented complaining of facial asymmetry and malocclusion. She had received surgery for a malignant tumour in the right retromolar region 7 years previously. It was considered that contraction of the pterygoid muscle by surgical injury caused anterior meniscal displacement and TMJ dislocation. Since manual manipulation failed, direct open reduction was performed after separation of the lateral pterygoid muscle from the condylar head and removal of the intra-articular scar tissues. Although the condylar head was returned to the glenoid fossa, optimal occlusion was not obtained because of compensatory tooth movement and inclination. Satisfactory occlusion and symmetric facial appearance were brought about by post-surgical orthodontic therapy.
