Hyperplasia of the mandibular condyle. A historical review of important early cases with a presentation and analysis of twelve patients.

Thirteen patients with condylar hyperplasia have been examined and twelve operated upon in a nine year period ending December 1979. A further eight patients with facial asymmetry, considered to be the sequelae of condylar hyperplasia, had extra condylar osteotomies carried out. As no specimens are available for histopathological examination, they have been excluded from the series. There appears to be a similarity between the histological findings of osteochondromata of the mandibular condyle and coronoid processes, active condylar hyperplasia and the changes noticed in the region of the costo-chondral junction of the acromegalic rib.
