Peripheral Osteoma of Mandibular Angulus: Analysis of the Literature and Report of a New Case

Abstract

Osteoma is a benign osteogenic neoplasm originating from the continuous proliferation of compact and/or cancellous mature bone. The tumor can be classified as peripheral, central or extra-skeletal regarding location and it commonly seen in the cranio-facial region especially at the skull and paranasal sinuses. The exact etiology of the tumor is still controversial; however, it is considered that infection, trauma, muscle activity contributes the occurrence of the tumor. Due to the slow growing nature of osteoma, it is coincidentally detected on radiographs or when the tumor reaches a large size enough to trigger symptoms and cause facial disfigurement. Although mainly detected in the craniofacial bones, osteomas are rarely located in the jaw bones. The purpose of this review, is to present the diagnosis and treatment plan of a peripheral osteoma in the mandibular angulus region of an 8-year-old boy together with a review of published cases of peripheral osteomas of mandibular angulus.
