Demographic features in Unilateral Condylar Hyperplasia: An overview of 309 asymmetric cases and presentation of an algorithm.

摘要: Purpose: Unilateral Condylar Hyperplasia (UCH) is an acquired deformity of the mandible, which can highly influence symmetry face due to its progressive nature. It caused by growth resembling pathology in one mandibular condyles. Definition as well classification subject discussion. The aim this study evaluate a large cohort alleged UCH patients, and describe clinical characteristics, demographic features, follow up. Secondly algorithm presented, order achieve uniformity diagnosis treatment. Patients methods: From 1994 2014 database consecutive patients from 3 maxillofacial departments (Academic Medical Center, Amsterdam; VU Amsterdam Spaarne Gasthuis, Haarlem) with suspected was set were referred orthodontists, dentists, general practitioners or surgeons. Demographic bonescan outcomes, laterality, follow-up noted. Secondarily, all retrospectively diagnosed surgeon (JWN), using available documentation. Missing data additionally retrieved orthodontic offices. Results: 394 asymmetric evaluated. In 309 (78%) justified SPECT available. mean age at presentation 20.3 years (SD ± 7.7, range 9.0–54.5 years). 48% positive. 80% these received surgical treatment, 62% treated condylectomy only, 33% plus additive corrective surgery, 5% underwent surgery only. Of patient group without positive 42% treatment: 34% 15% 51% total (N = 309) 96 (31%) only treatment 124 (40%) no all. Treatment could be finalized further 64% 41% respectively. comparison noted clinician author (JWN). 72% cases, secondary screening agreement initial classification. Conclusion: Based on not (active) require (orthognathic) surgery. A (transoral) partial for active recommended, postoperative remodeling period 6 months Second stage correcting may necessary upon evaluation, orthognathic diagnostic planning procedures. appears difficult classify reliably radiological Objectivity quantification process necessary: documentation parameters. attached form recommended.
