Abstract
Objective: Osteochondroma or osteocartilaginous exostosis, is a cartilage-capped exophytic lesion that arises from the cortex of a bone. Although osteochondroma is considered as the most common tumor of skeletal bones, it is relatively rare in the jaw. The osteochondroma of the mandible occurs at the condyle or the tip of the coronoid process whereas called Jacob’s Disease when mandibular coronoid process is involved. In this report, we present an osteochondroma case extending from the mandibular condyle to the cranial base. Case: A 55-year male patient was referred to Department of Oral and Maxillofacial Surgery of Bezmialem Vakif University Dentistry Faculty with complaints of mouth opening limitation and facial asymmetry. The distance of maximum mouth opening was 9 mm in length. A computed tomography scan showed the right condylar processes hyperplasia. The condyle and pathological segment resections were performed with interpositional gap arthroplasty and abdominal fat graft was preferred. After the operation, the patient’s maximal incisal opening was 45 mm. Pathological examination revealed irregularly arranged fibrous, cartilaginous and bony elements. Based on histological features, a final diagnosis of osteochondroma was made. No complaints were reported by the patient during 1-year follow-up. Conclusion: Osteochondroma is rarely seen on the mandibular condyle. Clinical symptoms may be similar in many temporomandibular joint diseases such as ankylosis, Jacob’s Disease etc. Therefore the differential diagnosis should be well done. Gap arthroplasty is commonly recommended as the best treatment option in such cases.
