Peripheral Osteoma of the Zygoma

Abstract

Osteoma is a benign, slow growing lesion that consists of compact or cancellous bone. Three types of osteomas could be classified: the central osteoma arising from the endosteum, the peripheral osteoma from the periosteum, and the extraskeletal soft tissue osteoma. in the craniofacial region, peripheral osteomas of the zygoma are quite rare. A literature review identified 7 cases of zygomatic arch and 3 cases of zygomatic body. This is the first report of zygomatic osteoma that was endoscopically removed. This report presents a rare case of osteoma of the zygoma and its endoscopic approach. The authors were able to confirm that endo-scopic approach of this zygomatic osteoma was safe and effective surgical choice.
