Peripheral Osteoma in a Middle-Aged Female: A Comprehensive Case Report

Abstract Osteoma is a benign, slow-growing osteogenic lesion that may develop in the craniomaxillofacial region, including the paranasal sinuses, temporal bone, and jaws. These tumors are composed of compact or cancellous bone and may present as peripheral, central, or extraskeletal variants. Peripheral osteomas originate from the periosteum and typically appear as unilateral, well-defined, pedunculated, mushroom-like masses. Although peripheral osteomas involving the mandible are uncommon, those occurring in the mandibular notch are particularly rare. This report describes a peripheral osteoma of the mandibular notch in a 51-year-old nonsyndromic female, emphasizing its clinical presentation, radiographic features, and management considerations.
