Hyperplasia of the mandibular condyle: Considerations in a series of 12 patients

Abstract

Introduction: Condylar hiperplasia is defined as a pathological non neoplastic growth which compromises both size and shape of the mandibular condyle and is characterized by progressive facial asymmetry. Aim: To evaluate the efficacy and risks of surgical treatment of HC. Material and method: Descriptive study, cohort of cases. All patients between 2010 and February 2014 with diagnosis of condylar hyperplasia at Hospital Clínico P. Univer­sidad Católica de Chile were included. Results: Twelve patients were operated at our institution because of condylar hy- perplasia. Age average was 19.3 ± 3.4 years. The most frequent presentation was facial asymmetry. All patients were studied with single photon emission computed tomogra- phy (SPECT) with differential intake more than 50 ± 3.1% between both condyles. All patients were treated with mandibular condylectomy of the affected site and in 3 cases orthognatic surgery was performed at the same time of the condylectomy to correct dental malocclusion. Average follow up was 16 months (5 to 54 months). All patients re- covered facial symmetry and occlusion with absence of the previous joint dysfunction. Conclusions: Condylar hyperplasia is an unfrequent condition and surgery is effi- cient and safe for the treatment of the deformity.
