  • Osteoma is a slow growing benign osteogenic lesion characterized by proliferation of compact or cancellous bone. Osteomas may be classified as peripheral, central, or extraskeletal. Central osteoma arise from the endosteum, pheripheral osteoma from the periosteum, and extraskeletal soft tissue osteoma within a muscle. Peripheral osteoma of the mandible is uncommon. They manifest as asymptomatic, fixed tumors of bony-hard consistency that may be sessile or pedunculated. Radiographically, a well circumscribed round or oval radiopaque mass is seen. Here, we report a case of a huge solitary peripheral osteoma of the buccal posterior mandible in a 40-year-old woman who was otherwise in good health. The patient visited at the dental clinic because the lesion makes esthetic problem. Treatment was performed by surgical esthetic recontouring and histological examination. The patient remains free of recurrence after surgical esthetic recontouring operation.

  • Osteoma is a benign osteogenic tumor composed of cancellous or compact bone, classified as peripheral, central, or extraskeletal. Peripheral osteomas are uncommon. Excluding the maxillary sinuses, the maxilla is a rare site for osteomas. The purpose of this report was to describe clinicopathological and radiological features of two peripheral osteomas occurring in the jaws, one located in the mandible and another in the edentulous maxillary alveolar ridge. The tumors were asymptomatic and were fully excised without any complications or recurrence. The lesions were submitted to histopathological analysis and diagnosed as peripheral osteoma, compact type.

  • Osteomas are benign, slow-growing tumors that most frequently occur in the craniomaxillofacial region. These tumors are mostly asymptomatic and are generally found incidentally. A giant osteoma is generally considered to be greater than 30 mm in diameter or 110 g in weight. A 35-year-old female presented to us with complaints of a firm mass that showed continuous growth on the forehead following trauma. A hairline incision was made to expose the osteoma. Biopsy of the tumor confirmed a osteoma. There were no complications after surgery. Postoperative computed tomography revealed that the tumor was completely removed. Because a peripheral giant osteoma of the frontal bone with a history of trauma is a rare finding, thorough history-taking, physical examination, and preoperative imaging tests are needed for patients with a history of trauma to rule out a giant osteoma.

  • Osteoma is defined as a benign neoplasm of bony tissue. Osteomas are divided into two groups: central and peripheral by origin, compact and cancellous by histopathologic findings. Solitary osteoma of jaw bone, not related with Gardner syndrom, is relatively uncommon. We present two cases of huge solitary peripheral osteomas: compact type exophyting osteoma on the inferolingual side of mandibular angle and cancellous type on the residual ridge of posterior maxilla, which is extremely rare.

  • Osteoma is benign tumor composed of mature compact or cancellous bone. Generally it is classified as periosteal(or peripheral) osteoma and endosteal(or central) osteoma by its origin. Clinically, periosteal osteoma on forehead is usually asymptomatic. From March 2002 to February 2005, We experienced 20 patients(23 cases) of histologically confirmed frontal osteoma. 20 patients are classified as sex, age, the number of osteoma, size, location and shape. Out of 20 patients, 16 were female and 4 were male in sex and mean age was 46. 18 patients have only one lesion but one patient has two lesions and another patient has three lesions. The size of osteoma varied from $7{\times}5{\times}3mm$ to $16{\times}14{\times}6mm$ and mean size is $12{\times}10{\times}5mm$. All osteomas were located at midline of forehead and shape of attachment was all sessile type. Surgical excision was superficial ostectomy through direct cutaneous incision or endoscopic approach. we obtained satisfactory result without specific complication.

  • Osteomas are benign, slow-growing osteogenic lesions frequently found in the craniomaxillofacial region. They can be classified as peripheral, central, or extraskeletal. Reactive mechanisms to trauma or infection, as well as muscle traction, are thought to play a major role in the development of peripheral osteomas. In the present report, a 41-year-old woman presented with a slowgrowing, painless mass on her left eyebrow. She had suffered trauma 15 years prior. In the computed tomography scan, a 2.5×2×0.7-cm radio-opaque tumor was detected just medial to the left supraorbital foramen, and a peripheral osteoma was clinically diagnosed. An elective operation under general anesthesia was planned. Following a suprabrow incision, subcutaneous and intramuscular dissection was performed. In the surgical plane deep to the corrugator muscles and superficial to periosteum, a branch of the supratrochlear nerve was encountered and preserved using a vessel loop. The osteoma beneath the periosteum was extracted in multiple fragments using a chisel and mallet to minimize trauma to the nerve. Contour and facial symmetry were corrected. To use a suprabrow incision, the surgeon must understand neighboring anatomical structures, including the course of the supratrochlear and supraorbital neurovascular bundles. When these structures are located adjacent to tumor lesions, careful surgical maneuvers should be performed to preserve them.

  • Purpose: To determine the clinical and radiological features of peripheral osteoma of the mandible (POM) in a Korean population and to compare with previous reports. Materials and Methods: Sixteen cases of POM found in 15 Korean patients who visited Seoul National University Dental Hospital between 1980 and 1998 were reviewed to determine their clinical and radiological features. Results: The 15 patients. five males and ten females. ranged in age from 22 to 69 years. with a mean age of 40.7 years. Six POMs were located on the buccal side of the mandibular body and five on the lingual aspect of the mandibular body and five on the lower border of the mandible. The duration of the lesion ranged between 1 and 10 years. The size of the lesions. in their great diameter. ranged from 6 to 26 mm. with a mean of 14.1 mm. Six POMs were pedunculated. nine sessile. and one bell-shaped. Eleven POMs were compact types and five were cancellous ones. Conclusion: The clinical and radiological features of these Korean series were broadly consistent with those of non-Korean populations reported previously. The principal difference was that all POMs under 35 year-old age were compact types.

  • Background: 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. Methods: 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. Results: 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. Conclusion: The epidemiologic data of our study will help plastic surgeons encounter frontal peripheral osteomas in the field to provide proper management for their patients.
