New method for treatment of intrabony vascular malformation of the mandible

    Vascular malformations are presented at birth. Some %35 of vascular malformations occurs in bone. Intrabony hemangioma may also occur and probably is indicative of either venous or arteriovenous malformations. The aim of this report was to assess previous studies and also presenting a patient with intrabony vascular malformation.   A twenty - year old man with an extensive multi-locular radiolucent lesion at the right side of mandible with bone destruction, buccal and lingual cortex expansion, malocclusion, teeth displacement, facial asymmetry, and bleeding after tooth extraction or biopsy was referred for control of bleeding. Intra - osseous hemangioma was diagnosed by clinical and para - clinical (panoramic - computerized tomography - angiography) examinations. Following access to external carotid artery by a vascular surgeon and retraction of buccal and lingual soft tissues, the right side of mandible was resected (from middle portion of ramus to left central incisor). After complete curettage of lesion and inter - maxillary fixation, the mandibular bone was fixed at its exact location by using three plates and ten screws for six weeks.   The advantages of this method are:   The use of patient's bone for mandibular reconstruction bypasses the process of bone harvesting from another site (iliac - calvarium), Shorter time of surgery and general anesthesia and lower morbidity rate, Intra - orally approach leaves no scar on the skin.
