INTRODUCTION: Superolateral disclocations of the temporomandibular joint are rare. They mostly occur after high-energy trauma and are frequently associated with fractures of the mandibular body.
CASE REPORT: A 35-year-old man was admitted for the management of a high-energy craniofacial trauma due to a road accident. The initial assessment revealed bilateral superolateral temporomandibular joint disclocations, with bilateral sagittal fractures of the condyle head and a fracture of the right parasymphysis. The treatment consisted in an external reduction of both condyles, followed by open reduction and internal fixation of the parasymphysis. The patient quickly started physiotherapy after the procedure and recovered a normal mouth opening after a month of follow-up.
DISCUSSION: For most authors, a quick management of superolateral dislocations is necessary in order to achieve a proper reduction of the temporomandibular joint dislocation and avoid surgical reduction. Temporomandibular joint ankylosis is the main complication of such lesions. Early physiotherapy is indicated in order to prevent ankylosis.
