BackgroundCondylar hyperplasia is a non-neoplastic overgrowth of the mandibular condyle. The disorder is progressive and causes gradual jaw deviation, facial asymmetry, and dental malocclusion. The only treatment capable of stopping hyperplastic growth is surgical condylectomy to remove the upper portion of the condyle containing the deranged growth center. When this procedure is conducted in proportion to the length of the healthy side it may also correct the jaw deviation and facial asymmetry.ObjectivesTo assess the degree to which condylectomy corrects the asymmetry and to determine the proportion of patients after condylectomy who were satisfied with the esthetic result and did not desire further corrective surgery.MethodsWe conducted a retrospective analysis of medical records of patients who underwent condylectomy that was not followed by corrective orthognathic surgery for at least 1 year to determine the degree of correction of chin deviation and lip cant. Patient satisfaction from treatment or desire and undergo further corrective surgery was reported.ResultsChin deviation decreased after condylectomy from a mean of 4.8⁰ to a mean of 1.8⁰ (P < 0.001). Lip cant decreased after condylectomy from a mean of 3.5⁰ to a mean of 1.5⁰ (P < 0.001). Most patients (72%) were satisfied with the results and did not consider further corrective orthognathic surgery.ConclusionsProportional condylectomy could be a viable treatment to both arrest the condylar overgrowth and achieve some correction of the facial asymmetry.
