Abstract

Condylar hyperplasia and condylar resorption are acquired disorders that affect the temporomandibular joint (TMJ) resulting in skeletal facial deformities and abnormalities in occlusion. The surgical correction of these deformities can be challenging, due to the variable period of abnormal condylar activity. Operative intervention has to be timed appropriately after necessary diagnostic investigations have established that active changes in the condyle have ceased. Skeletal scintigraphy serves as a useful diagnostic tool and treatment planning aid in the management of these skeletal facial deformities, as it detects metabolic bone activity and areas of active bone formation in the condyles. The goal of treatment is to achieve a stable functional occlusion without relapse, normal TMJ function and facial symmetry and balance. We present the etiology, the natural history and progression of these two TMJ disorders; discuss investigations and treatment of the resulting deformities with illustrations of surgical techniques and examples of clinical cases.
