Osteochondroma is a common benign bone tumor and although its involvement in facial bones is rare (0.6 %), it shows a strong predilection for developing in the mandibular condyle, causing occlusal changes and facial asymmetry. The aim of this study was to report a clinical case and the treatment of a 43-year-old male patient, who was diagnosed with condylar osteochondroma. Clinically, the patient presented an increase in volume in the right condylar region, deviation of the mandible to the left side and malocclusion. His main complaint was his facial asymmetry. Imaging exams showed changes in the size and morphology of the right condyle, and signs of hyper-capture on scintigraphy. The hypothesis of condylar hyperplasia and osteochondroma was raised. A virtual planning and execution of an orthognathic surgery of the jaws was performed to correct the occlusion and facial asymmetry, besides a low condylectomy to remove the lesion. Procedures such as high, low, proportional condylectomy, orthognathic surgery and TMJ reconstructive surgery are alternatives for the treatment of these pathologies. In our case, the orthognathic surgery combined with a condylectomy proved to be promising, to correct the occlusion and the facial asymmetry of the patient.

KEY WORDS: condylectomy, facial asymmetry, orthognathic surgery, osteochondroma.
