Early interceptive treatment of asymmetry.

Severe asymmetry in pre-adolescent children usually arises either from congenital anomalies, such as unilateral condylar hypoplasia, or as a result of juvenile rheumatoid arthritis, condylar hyperplasia or early fracture of the mandible. Early surgical and orthodontic interceptive treatment of the asymmetry is important for normal development of the face and jaws.
