Superolateral Dislocation of Bilateral Mandibular Condyles With a Mandibular Body and Condyle Fracture.

An 82-year-old man fell from a motorcycle and was admitted with superolateral dislocation of the bilateral mandibular condyles. The displaced condyles on the right and left were hooked in the posterior root of the zygomatic arch and in the temporal fossa beyond the zygomatic arch, respectively. There was a sagittal split fracture on the medial side of the right mandibular condyle and a right mandibular body fracture. Under general anesthesia, manual reduction of the dislocation was successfully performed the day after the injury. Bilateral superolateral dislocations hooked to the temporal fossa or zygomatic arch are very rare, as they may require multiple strong impacts to occur. Open reduction and closed reduction are possible treatment modalities, and the period from trauma to treatment is relevant for the choice of treatment.
