Osteochondromas are benign, cartilage-covered bone tumors that occur very rarely in the mandibular or facial region. If functionally relevant structures such as the condylar process or the coronoid process are involved, functional impairments may occur. Possible symptoms include facial asymmetry, movement impairment, malocclusion, and pain (especially during occlusal function). Osteochondroma treatment falls within the scope of oral-maxillofacial surgery, and treatment options vary depending on tumor size and growth. In the case described here, a 39-year-old female presented with complaints of pain in the right temporomandibular joint (TMJ) region, increasing facial asymmetry, and limited jaw opening. Imaging studies revealed the presence of a tumor on the right condyle, which was removed by conservative excision. Complete tumor excision was not achieved. However, no tumor growth has been observed to date, after 15 years of follow-up. Keywords: osteochondroma, primary bone tumor, condylar process, excision, recurrence
