Aesthetic and functional reconstruction in intraosseus hemangiomas of the zygoma.

The incidence of intraosseus hemangiomas is very low. The mandible, the zygoma, the maxilla, and the frontal bone are the most frequent areas of localization in the craniomaxillofacial region. Surgery, without preoperative embolization, is always the best treatment for intraosseus hemangiomas of the zygoma. The radical removal of the tumor frequently causes a contour defect that has to be corrected. Calvarial grafts provide a good solution to the problem of reconstruction of bone loss. They are easy to prepare, near to the implant zone, and they do not require changes in the patient's position during the operation. The implants fixed by micro- and minifixation systems provide a good functional and aesthetic result. We, after a review of the literature on intraosseus hemangiomas of the craniomaxillofacial region, report two cases of intraosseus hemangiomas of the zygoma in which removal of the tumor and reconstruction with calvarial grafts have been performed.
