Osteochondroma is a benign, juxtacortical, cartilage-tipped protuberance that commonly affects the long bones.1 It is the most common benign tumor of the long bones but is relatively rare in the facial skeleton, where it most commonly affects the coronoid process, followed by the condyle. As osteochondroma of the mandibular condyle almost always presents as an anteromedial growth along the direction of the lateral pterygoid muscle, the presenting complaints are usually associated with decreased mouth opening and deviation in mouth opening toward the unaffected side.2

The present report describes an atypical case of osteochondroma of the mandibular condyle in a young man after mandibular dislocation. The condylar dislocation occurred from the active mouth opening exercises, because the patient had been experiencing prolonged reduced mouth opening secondary to a corrosive burn of the buccal mucosa. The aim of the present report was to describe an atypical presentation of an uncommon lesion and its management and to discuss a previously unreported complication after mandibular dislocation.
