Condylar hyperplasia.

Condylar hyperplasia (CH), as the name suggests, affects mandibular condyle producing overgrowth of condyle, which is characterized by a slowly progressive, usually unilateral enlargement of the mandible, facial asymmetry and deviation of chin to the unaffected side. The condition is known to be self-limiting, usually begins around puberty, but may not be recognized until later in life. This paper reports a case of severe facial asymmetry secondary to CH, which was successfully treated by high condylectomy only.
