Abstract
Background and objectives: Unilateral condylar hyperplasia (UCH) is a rare asymmetric condition of the mandible due to condylar pathology resembling growth, with unknown aetiology. Obwegeser et al.1 described a classification in 3 categories: hemimandibular elongation (HE), hemimandibular hyperplasia (HH) and a combination of these two (hybrid form), using panoramic radiographs and clinical features. Three dimensional quantification of asymmetry in UCH is not reported yet, but would be useful for diagnosing and evaluating the degree of deformity in this disease.
