Osteochondroma is the most common benign bone tumor, representing 10 to 15% of all bone tumors. We present the case of a 44-year-old patient who presented with progressive deviation to the right of 6 months evolution. On examination, he presented facial asymmetry with a right crossbite. The imaging study revealed an exophytic mass of 16x7x10mm located cranially and laterally in relation to the head of the left mandibular condyle, being compatible with an osteochondroma. Complete excision of the lesion was realized using a preauricular approach, accompanied by an arthroplasty with discopexy with an anchor. After the surgical intervention, the patient performed physiotherapy and continued with orthodontic treatment. Condyle osteochondroma is an unusual pathology, until 2010 there were ninety-eight cases described and there are no established treatment algorithms. The objective of this work is to present a case of osteochondroma of the mandibular condyle treated by arthroplasty with preservation of the articular disc.
