“…Osteomas may be a reactive or inflammatory lesion which arise as a result of trauma or chronic infection in the paranasal sinuses leading to the proliferation of osteogenic cells [12]. The traction of medial pterygoid, lateral pterygoid and temporalis muscle may be a possible etiologic factor since peripheral osteomas are reported in areas of close proximity with these muscles [3]. In our cases, Case 1 revealed a history of chronic irritation due to the ill-fitting dystrophic calcifications [6].…”

“…Osteomas have a lower incidence rate of 0.01-0.04% among general population and it constitutes 2.9% of all bone tumors and 12.1% of benign bone tumors [10]. Peripheral osteoma appear as a pedunculated mushroom like masses of 1-4 cms in size originating from the periosteum of the bone and are frequently encountered in the paranasal sinuses [3,7]. Peripheral osteomas of the jaws are reported more frequently in the mandible compared to maxilla with lingual aspect of the body and inferior border of the angle of the mandible being the common site [12].…”

“…The osteomas are reported to be arising frequently from either endosteal or periosteal regions of the craniofacial bones such as temporal bone, pterygoid process, sinuses, maxilla and rarely from the mandible [1,2]. They can be classified as central (arising centripetally from the endosteum), peripheral (arising centrifugally from the periosteum) and extra skeletal (arising from the muscle or dermis of skin) types based on the site where the tumor originates in relation to the cortical bone [2,3]. The peripheral osteoma (also known as parosteal or periosteal or exophytic) are frequently encountered in the paranasal sinuses (frontal, ethmoid, maxilla) and the other locations include mandible, temporal bones, pterygoid process and orbital wall [1].…”
Osteomas are benign osteogenic tumors that are characterized by the proliferation of either cancellous, compact or a combination of both. Central and peripheral are two types of osteomas. In this article, we report two cases of osteomas that were clinically diagnosed as mandibular tori. The radiographic, computed tomography, three-dimensional computed tomography (3DCT) and histopathological investigations were employed in achieving final diagnosis. Both cases were managed by surgical excision. This article aims to discuss the cases presented with literature review on diagnosis and management.

“…Extraoral approach is preferred for peripheral osteomas that are located in the posterior region of the mandible. Recurrence after complete excision is very rare and malignant transformation has not been reported in the literature [ 11 , 12 ]. In our case, the patient was reported with a lesion at the angle of the mandible and hence an extraoral approach was used.…”
Solitary peripheral osteoma is a benign, slow-growing osteogenic tumor arising from craniofacial bones such as the sinus, temporal, or jaw bones but rarely originating from the mandible. Osteoma consists of compact or cancellous bone that may be of peripheral, central, or extraskeletal type. Peripheral osteoma arises from the periosteum and is commonly a unilateral, pedunculated mushroom-like mass. Solitary peripheral osteomas are characterized by well-defined, rounded, or oval radiopaque mass in the computed tomography. Although multiple osteomas of the jaws are a hallmark of Gardner's syndrome (familial adenomatous polyposis), nonsyndromic cases are typically solitary. Herein, we report a rare case of solitary peripheral osteoma of the angle of the mandible in a 27-year-old female with clinical, radiologic, and histopathologic findings.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
