Eight Cases of Interosseous Cavernous Hemangioma of Frontal Bone

Abstract

　　Cavernous hemangioma of the skull is a rare pathological diagnosis, accounting for 0.2% of bone tumors. Here, the authors describe eight Japanese cases of frontal bone hemangioma. Five men and three women aged from 36 to 54 years were studied. The lesions were situated in the frontal bone: two in the supraorbital region and the rest in the forehead. En-bloc resection including perilesional bone was performed in all cases. Following resection, the bone defect was reconstructed immediately using the outer or inner table of the split calvarial bone harvested from the same region. Patients have been followed up for between 48 and 180 months post-operatively, maintaining a good contour and showing no evidence of recurrence. The choice of surgical technique is important for long-term outcomes regarding both esthetics and complete resection.
