Use of an Ultrasonic Aspirator in Removal of an Orbital Rim Hemangioma.

Intraosseous hemangiomas are rare bony neoplasms that infrequently develop in the calvarium or facial bones. Due to their highly vascular nature, biopsy or resection of these tumors can present a surgical challenge, with reports of significant blood loss during tumor resection. Traditional surgical resection of intraosseous hemangiomas often includes the use of high speed oscillating or sagittal saws. Ultrasonic aspirators, which spare adjacent soft-tissue structures and minimize blood loss, have been successfully used in resection of firm soft tissue masses of the orbit; however, this technology has not been demonstrated in the treatment of a vascular tumor in the orbit. The authors present the case of a 37-year-old woman who presented with an intraosseous hemangioma at the left inferior orbital rim and maxilla; the mass was successfully resected with the aid of a Sonopet Ultrasonic Aspirator bone knife. The knife allowed for simultaneous emulsification and cautery of the bone encasing the mass with low risk to sensitive surrounding tissue.
