One-stage treatment of acquired facial deformity caused by severe unilateral condylar hyperplasia

Abstract

Condylar hyperplasia (CH) is a rare and self-limiting process manifesting between the first and third decades of life. It causes facial asymmetry and derangement of occlusion. The management involves resection of the condylar head and orthognathic surgery followed by orthodontic treatment. We present a 33-year-old man with spontaneous onset of CH during a span of 10 years. This was managed with resection of the condyle alone, which dramatically improved facial asymmetry in addition to restoration of the occlusion within a few months of follow-up. Therefore, orthognathic surgery or orthodontic treatment was not needed.
