[Hypercondylia and lateral deviations of the mandible (author's transl)].

Hypercondylia is a relative rare, benign affection presenting as asymmetry of the lower facial region with laterognathia, dental articulation disorders, and minimal functional effects on the temporomandibular joints. These clinical manifestations, confirmed by the presence of lesions of the condylar region on radiological examination, vary as a function of the directional axis and course of the hyperplasia. Various distinct and sometimes extremely different radioclinical pictures can therefore be distinguished. Therapy aims at re-establishing facial harmony and restoring altered dental articulation. Whereas minor anomalies can be corrected by orthodontic or prosthetic treatment associated with plastic surgery, severe abnormalities require major reconstructive surgery as determined by orthopedic investigations.
