Central Osteoma of the Maxilla With Involvement of Paranasal Sinus

Abstract

Osteoma is an osteoblastic benign tumor characterized by the proliferation of either compact or cancellous bone. In the jaws, the most of cases reported in the literature presented as peripheral solitary lesions, involving preferably the posterior region of the mandible. However, central osteomas are quite rare, especially in the maxillary bone. The purpose of this article was to present the clinical, radiographic, surgical, and histologic features of a solitary central osteoma of the maxilla with involvement of the paranasal sinus and to review the literature for central osteomas located in the jaws. Our clinical report participates to literature as the 12th case of central osteoma in the jaws and the fourth case in the maxillary bone.
