[Surgical treatment of hemangioma of bones of the orbito-zygomatic region].

The incidence of intraosseous haemangiomas is very low. The mandible, the zygoma, the maxilla and the frontal bone are the most frequent areas of localization in the craniomaxillofacial region. Pain and swelling are the most important symptoms of these tumors when they are localized in the orbit or in zygoma. Surgery, without preoperative embolization is always the best treatment for intraosseous haemangiomas of the zygoma. The radical removal of the tumor frequently causes a plain aesthetical loss which has to be restored. Calvarial grafts are a good solution to the problem of reconstruction of bone loss. They are easy to prepare, near to the implant zone, and they don't need changes of the patient's position during the operation. The implants fixed by mini- and micro-fixation systems provide a good functional and aesthetical result. The authors, after a review of the literature about intraosseous haemangiomas of the cranio-maxillofacial region, report two cases of intraosseous haemangioma of the zygoma in which removal of the tumor and reconstruction with calvarial grafts has been performed.
