Condylar hyperplasia causing progressive facial asymmetry during orthodontic treatment--a case report

Condylar hyperplasia is defined and its aetiology and prevalence are briefly reviewed. A case is presented to illustrate how the progressive nature of the condition can create problems for the clinician, particularly during orthodontic treatment of a child or adolescent patient. The benefits of interceptive surgery are illustrated, although such an approach does not necessarily mean that further surgery is avoided at the completion of growth.
