Peripheral Osteomas Research Articles

Frontal peripheral osteomas: a retrospective study.

Osteomas are benign, slow-growing bone tumors that can be classified as central, peripheral, or extraskeletal. Central osteomas arise from the endosteum, peripheral osteomas from the periosteum, and extraskeletal osteomas within the muscle. Frontal peripheral osteomas are mainly encountered in plastic surgery. In this study, we retrospectively analyzed the clinical data of patients with frontal peripheral osteomas. We retrospectively reviewed the medical records of patients who visited our hospital with frontal peripheral osteomas between January 2014 and June 2022. We analyzed the following variables: age, sex, tumor type (sessile or pedunculated), single or multiple, size, history of head trauma, operation, and recurrence. A total of 39 patients and 41 osteomas were analyzed, of which 29 osteomas (71%) were sessile and 12 osteomas (29%) were pedunculated. The size of the osteomas ranged from 4 to 30 mm, with an average size of 10 mm. The age of patients ranged from 4 to 78 years with a mean age of 52 years. There were seven men (18%) and 32 women (82%), and the man-to-woman ratio was 1:4.6. Two patients (5%) had multiple masses, with two osteomas in each, while only two patients (5%) had a history of head trauma. Twenty-nine patients (74%) underwent ostectomy by a direct approach, and none of the patients experienced recurrence. The epidemiologic data of our study will help plastic surgeons encounter frontal peripheral osteomas in the field to provide proper management for their patients.

Giant mandibular osteoma: A case report and review of literature

Osteomas are benign osteogenic lesions that result from the proliferation of mature bone. Three variants are known: central, peripheral, and extra skeletal. The peripheral variant is the most common and it most frequently affects the paranasal sinuses, rarely occurring in the jaws. Mostly peripheral osteomas are of small size and rarely requiring surgical treatment. Multiple osteomas occur in Gardner’s syndrome however isolated lesions are non-syndromic. Neoplastic, inflammatory, developmental and traumatic theories are given as etiologic causes. Here we have described a case of 66-year-old female patient who developed a giant peripheral osteoma in mandibular body region which was managed surgically and no recurrence noticed. Radiological evaluation portrayed a different picture and histopathology confirmed the diagnosis.

An atypical large unilateral torus mandibularis: Case report and review of literature

Benign bony exostosis can be present in the maxilla or mandible. They are non-odontogenic sclerotic lesions which present as bony outgrowths on the jaws. On the lingual aspect of the mandible, these benign bony exostoses resemble peripheral osteomas and when present adjacent to bicuspids they are known as torus mandibularis (TM). Usually these TM are small, bilateral and asymptomatic. This article presents an atypical case of large nodule of unilateral TM associated with discomfort in a 46-year-old male patient with partially edentulous jaws. The bony outgrowth was surgically removed and follow up period of 6 months was uneventful. Review of the literature was undertaken for various etiological factors, clinical features and management of torus mandibularis.

A RARE CASE OF BILATERAL OSTEOMA OF THE MANDIBLE

Facial osteomas are a rare occurrence, with only a few cases recorded in the literature. Osteomas are well-differentiated developed bone neoplasms that are generally asymptomatic. It is a benign, slow-growing osteogenic tumour that usually arises from craniofacial bones such the sinus, temporal, or jaw bones, but rarely the mandible. Osteoma is a type of bone that is compact or cancellous and can be peripheral, central, or extraskeletal. Peripheral osteoma is a unilateral, pedunculated mushroom-like mass that originates from the periosteum. In computed tomography, solitary peripheral osteomas are identified by a well-defined, rounded, or oval radiopaque mass. Here we present a rare case of bilateral osteoma of the mandible.

SOLITARY PERIPHERAL OSTEOMA OF THE MANDIBLE: A CASE REPORT

Osteomas are benign, slow growing oestrogenic tumours. They are often occurring in the craniofacial bones but rarely originate from the mandible. Osteomas have three varieties as central, peripheral and extra skeletal. Central and peripheral osteomas are often seen in the facial bones. Peripheral osteoma often located in the frontal, ethmoid and maxillary sinus, but rarely occurs in the jaws. Usually they are asymptomatic and discovered incidentally during radiological and clinical examinations. Osteomas are characterized with well-defined, rounded or oval radiopaque mass in the computed tomography. Herein, we report a rare case of peripheral osteoma of the lower part of the mandible in a 21-year-old male with radiologic and pathologic findings.

Giant Osteoma of the Mandible: Report of a Rare Case with Review of Literature.

Osteoma is a slow growing, asymptomatic, benign bony tumor composed of compact and cancellous bones. Central, peripheral, and extra skeletal osteomas are the three types based on the site of origin. They are mostly observed on routine radiographic screening, mostly in the paranasal sinuses. Gnathic involvement is an uncommon occurrence, and if present, mandibular involvement is more frequently seen. Mostly, osteomas are small asymptomatic lesions and very rarely they become symptomatic and acquire larger size. Multiple osteomas are a feature of Gardner's syndrome; however, solitary osteomas are non-syndromic. Oral health professional may be the first to diagnose Gardner's syndrome as the osteomas may be initial manifestation of the disorder. Treatment protocol of osteomas varies based on the associated signs and symptoms. Small, asymptomatic cases are treated conservatively by periodic clinical and radiographic evaluation. However, larger, symptomatic lesions require surgical intervention. Herby, reporting an unusual case of Giant peripheral osteoma of the mandible. Our case is unique in few aspects because of its unusually large size (5 × 4cm) and involvement of lingual aspect of the mandible in the region of sublingual fossa, with compression of the floor of mouth.

Peripheral osteoma of the mandible –an unusual presentation

Osteoma is a benign osteogenic, mostly asymptomatic tumour characterized by proliferation of cancellous/compact bone. It is one of the rare entity with 0.01-0.4% prevalence, and 2.9% of all tumors; 12.1% of all benign tumors. This could be Central, Peripheral, or Extra-skeletal in location mostly occurring in the Cranio-facial bones. Peripheral osteomas are rare to occur in the jaws with predilection to mandibular lingual aspect of body, angle, and inferior border. We here report a case of 15 year boy with swelling in front of left ear. Clinical and radiographic examination brought us to a working diagnosis as Osteoma in the buccal aspect of left ramus of mandible, which is huge in size. Thorough examination is done to rule out any syndromes associated with it, such as Gardner’s Syndrome. Following which surgical excision is done under general anesthesia, and an 8 months regular follow-up reveals no recurrence. Keywords: Osteoma, Osteogenic, Benign.

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

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.

Solitary Peripheral Osteoma of the Hard Palate: Case report and literature review

Osteomas are benign slow-growing osteogenic lesions of unknown aetiology which can be central, peripheral or extraskeletal. Peripheral osteomas of the maxilla are very uncommon. We report a 72-year-old female patient who presented to the Department of Oral & Maxillofacial Surgery, Dental School of Athens, Athens, Greece, in 2015 with swelling of the palate following a tooth extraction. Clinical and radiographical features were indicative of a solitary peripheral osteoma of the hard palate. An excisional biopsy and histological examination of the lesion confirmed the diagnosis. No complications occurred during the postoperative period and there was no evidence of recurrence at a one-year follow-up.

Peripheral Solitary Osteoma of the Zygomatic Arch: A Case Report and Literature Review.

Osteoma is a benign slow-growing osteogenic neoplasm commonly occurring in the craniofacial skeleton, characterized by the proliferation of compact and/or cancellous bone. Osteomas may be peripheral, central, or extraskeletal. Peripheral osteomas arise from the periosteum and are quite uncommon in the jaw bones. The exact aetiology and pathogenesis of peripheral osteoma are unknown. Clinically, peripheral osteomas are usually asymptomatic, but depending on the location and size of the lesion, it may cause swelling, pain, esthetic disfigurement and functional impairment. On radiological imaging, a peripheral osteoma appears often as well-circumscribed, round to oval, pedunculated radiopaque mass attached to the cortex by a broad base or a pedicle. Asymptomatic osteomas are treated conservatively, while surgical excision is indicated when the lesion is symptomatic, actively growing, or for cosmetic reasons. Histologically, osteomas are composed of a normal-appearing, dense mass of lamellar bone. Recurrence of peripheral osteoma after surgical removal is extremely rare and there are no reports of malignant transformation. A review of the literature disclosed only 7 well-documented cases of peripheral osteoma located at the zygomatic bone. The purpose of this article is to present the clinical, radiographic, surgical and histological features of a solitary peripheral osteoma of the left zygomatic arch in a 55-year-old woman and to review the literature about this uncommon pathologic entity.

Solitary peripheral osteoma of the body of the mandible

Osteomas are benign osteogenic tumors that are often slow growing and frequently arising in the craniofacial bones and rarely originating from the mandible. Central, peripheral, and extraskeletal are the three varieties of osteomas of which the central and the peripheral types are commonly seen in the facial bones. Peripheral osteomas most commonly were seen in the frontal, ethmoidal, and maxillary sinus and very rarely seen in the jaws. Typically asymptomatic in nature, osteoma presents itself as a welldefined radiopaque mass. Herein, we report a rare case of peripheral osteoma of the body of the mandible of a 45-year-old female patient.

Radiofrequency ablation of spinal osteoid osteoma: a prospective study.

OBJECTIVE Surgery has been considered the standard treatment for spinal osteoid osteomas that are refractory to analgesic agents. Radiofrequency ablation (RFA) is a less invasive technique with established efficiency for the treatment of peripheral osteoid osteomas. The main objectives of this study are to evaluate the safety of RFA based on the results of a previous experimental study in rats conducted in the authors' laboratory and to identify its short- and long-term efficiency in the treatment of spinal osteoid osteomas. METHODS Between March 2009 and July 2016, 8 consecutive patients with spinal osteoid osteomas were enrolled in the study and underwent 9 CT-guided RFA procedures. All patients presented with spinal pain (median preoperative visual analog scale [VAS] score 7.55, range 6-8.8) predominantly during the night, and they all had normal neurological examination results before the procedure. Pain (according to the VAS score) and neurological status were reassessed immediately before discharge, with further follow-up at 1, 6, and 12 months after the procedure. At the final follow-up, VAS score, neurological examination, patient satisfaction, and a radiological control (CT scan) were documented (median 48 months, range 12-84 months). VAS scores before and after the procedure were compared during the 3 days before surgery (D0), on the day of the surgery, Day 1 (D1), and at the final follow-up. RESULTS No neurological deficit was documented following the procedure or at the final follow-up. A statistically significant reduction in the VAS score was observed on Day 1 (mean 2.56 ± 0.68, p = 0.005) compared with D0. At the final follow-up, all patients reported a VAS score of 0 and a satisfaction rate of 100%. Only 1 patient had recurrent symptoms (pain, VAS score 8.1) 6 months after the initial RFA. A second procedure was performed, and the patient was subsequently symptom free at the final follow-up. CT scanning performed in all patients (12-84 months post-RFA) showed residual sclerosis in 4 patients and complete resolution of the radiological lesion in the remaining 4 patients. CONCLUSIONS CT-guided RFA appears to be a safe and effective method for the management of spinal osteoid osteoma and can be safely performed for lesions close to the dura or exiting nerve root based on the motor response threshold testing performed during the procedure. It should be considered the treatment of choice for spinal osteoid osteomas refractory to conservative treatment, thus avoiding more aggressive spinal approaches with subsequent potential morbidity.

Peripheral Osteoma in the Mandibular Angle.

Osteoma is a benign tumor that occurs from the proliferation of cancellous bone, compact bone, or their combination [1]. It can be classified into 3 types, namely, central, peripheral, and extraskeletal osteoma. Central osteoma occurs in the endosteum, peripheral osteoma occurs in the periosteum, and extraskeletal osteoma occurs mostly within muscles [2].

Peripheral osteoma of condylar neck following trauma

Osteomas are solitary, benign, slow-growing osteogenic tumors that sometimes involve the craniofacial region, such as the paranasal sinuses, temporal bone, or jaw bones. They can be classified as central and peripheral osteomas. The peripheral osteoma of the mandible is relatively uncommon. Though most of the cases involving the mandible arise from the mandibular body, angle, condyle head, or coronoid process, we report one such case unusually arising from the anterior surface of the neck of the condyle, the pterygoid fovea region. We believe it is the first recorded case of an osteoma arising from the pterygoid fovea region.

Solitary Peripheral Osteoma of the Angle of the Mandible.

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.

An Uncommon Case of Solitary Peripheral Osteoma in the Mandible.

Osteoma is a benign osteogenic lesion which is composed of well differentiated mature compact and/or cancellous bone that proliferates continuously. Its prevalence is 4%. Its pathogenesis is still controversial. Solitary peripheral osteoma of craniofacial region is a rare finding. We report a case of 30-year-old female having solitary peripheral osteoma present on the lingual cortex of the left posterior mandible which was initially asymptomatic but now is causing discomfort while chewing and not associated with Gardner's syndrome. We also laid emphasis on its clinical, differential diagnosis, radiological, surgical, and histopathological features. The aim of this paper is to present an uncommon case of solitary peripheral osteoma in the mandible along with analysis of literature for peripheral osteomas of jaws and to contribute to the knowledge concerning the pathogenesis, differential diagnosis, and management of these lesions.

Peripheral osteoma of the angle of mandible

Osteomas are benign osseous neoplasms that show continuous but slow growth and are characterized by the proliferation of compact and/or cancellous bone. The exact cause is unknown, and they are usually considered to represent hamartomas or reactive lesions secondary to low-grade inflammation. They can be classified into central, peripheral or extra-skeletal types. Peripheral osteomas occur most frequently in the frontal and ethmoid sinuses, and jaw involvement is rare. They are usually asymptomatic and may be discovered during routine clinical and radiographic examination. Radiographically, peripheral osteomas appear as oval radiopaque well-circumscribed masses attached to the cortex by a broad base or a pedicle. This article describes a case of a peripheral osteoma of the right angle of the mandible in a 20-year-old male along with a literature review.

Peripheral osteoma of the mandible with radiologic and histopathologic findings

Osteomas are benign, slow growing osteogenic tumors. They are often occurring in the craniofacial bones but rarely originates from the mandible. Osteomas have three varieties as central, peripheral and extraskeletal. Central and peripheral osteomas are often seen in the facial bones. Peripheral osteoma often located in the frontal, ethmoid and maxillary sinus, but rarely occurs in the jaws. Usually they are asymptomatic and discovered incidentally during radiological and clinical examinations. Osteomas are characterized with well-defined, rounded or oval radiopaque mass in the computed tomography. Herein, we report a rare case of peripheral osteoma of the lower part of the mandible in a 19-year-old female with radiologic and pathologic findings.

Peripheral Osteoma on the Buccal Aspect of Mandible Angle

Osteomas are radiopaque osteogenic tumors composed of slow-growing, painless, mature bone tissue. On the basis of their origin, they can be classified as central, peripheral, or extraskeletal. Osteomas occur primarily in the craniofacial region, and peripheral osteomas are most prevalent in the paranasal sinuses. We describe a rare case of peripheral osteoma on the buccal aspect of the left mandibular angle that caused facial deformity in a 68-year-old woman. We also discuss its differentiation from other similar radiologically radiopaque masses.
