Surgical excision of osteochondroma on mandibular condyle via preauricular approach with zygomatic arch osteotomy

Background Osteochondroma is a benign tumor that tends to develop in mandibular condyle and coronoid process in the craniofacial region. If tumor mass has grown from condyle into the infratemporal space with zygomatic arch obstructing the access, there are risks associated with surgical exposure and local resection of these masses. Case presentation This study reports on a case of osteochondroma on mandibular condylar head where we treated with surgical excision via preauricular approach with 3D analysis. After the local resection, there were no surgical and post-operative complications until 8-month follow-up period. Conclusions In local excision of osteochondroma, our method is a minimally invasive method. It is a good example of osteochondroma treatment.
