An unusual case of acquired unilateral condylar hypoplasia.

A case is described of acquired unilateral condylar hypoplasia, in which the right condyle seemed to have been fractured at an early age. There is evidence to suggest that the unresorbed condylar remnant persisted in the glenoid fossa and that a new condylar head had developed anterior to the articular emminence. This 'new head' showed a carrot-shaped radiolucent wedge suggestive of the condylar growth cartilage and, clinically, exhibited some growth potential. A complex composite odontome present in place of the mandibular right third molar may also have been caused by this early trauma.
