PULGAR B, Dahiana et al. Hyperplasia of the mandibular condyle: Considerations in a series of 12 patients. Rev. Otorrinolaringol. Cir. Cabeza Cuello [online]. 2015, vol.75, n.1, pp.27-34. ISSN 0718-4816.  http://dx.doi.org/10.4067/S0718-48162015000100005.

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 hyperplasia. Age average was 19.3 ± 3.4 years. The most frequent presentation was facial asymmetry. All patients were studied with single photon emission computed tomography (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 recovered facial symmetry and occlusion with absence of the previous joint dysfunction. Conclusions: Condylar hyperplasia is an unfrequent condition and surgery is efficient and safe for the treatment of the deformity.
