Review
Paranasal sinus osteoma is a slow-growing, benign, encapsulated bony tumor that may be commonly asymptomatic, being detected incidentally in 1% of plain sinus radiographs or in 3% of sinus computerized tomographic scans. In a patient presenting with orbital cellulitis and epiphora, computed tomography disclosed a large osteoma of the ethmoid sinus. Excision of the osteoma allowed recovery of vision, return of extraocular muscle function, and resolution of choroidal folds. Proptosis, diplopia, and visual loss are other frequent presenting signs of paranasal osteomas. Epidemiology, diagnosis, treatment, and pathologic findings in paranasal sinus osteoma are reviewed.

Osteoid osteomas that arise at the end of a long bone, within the insertion of the joint capsule (juxta-articular, intra-articular), may cause misleading clinical, radiographic, and histologic findings, resulting in unnecessary diagnostic tests and a delay in definitive treatment. To clarify optimum diagnostic procedures, we reviewed 20 cases of juxta-articular osteoid osteomas and found a mean delay from presentation to correct diagnosis of 24 months. Plain radiographs were either negative or showed only secondary changes. A periosteal reaction and proliferative synovitis with chronic inflammation was common, which could be misinterpreted as rheumatoid arthritis. Optimum diagnostic procedures were a bone scan followed by plain tomograms and an excisional biopsy of the nidus.

Review
BACKGROUND
Osteomas of the paranasal sinus are often asymptomatic and are sometimes complicated by mucoceles, but intradural extension of such a mucocele has rarely been reported.
CASE DESCRIPTION
This 67-year-old man with complaint of headache was diagnosed as having an intradural extension of a mucocele complicating an osteoma of the frontoethmoid sinus. A right frontobasal craniotomy was performed and a mucocele in the frontal sinus extending into the frontal lobe through two dural defects and the osteoma was removed completely. The patient was successfully treated without recurrence.
CONCLUSION
The importance of radical surgery for such lesions and the relationship between osteomas and mucoceles are discussed.

Review
OBJECTIVE AND IMPORTANCE
A relatively rare condition of intraparenchymal tension pneumatocele secondary to a frontal sinus osteoma eroding posteriorly and breaching dura mater is described. The scanty body of literature on this subject is briefly summarized, and the importance of this condition as a result of its life-threatening but readily treatable intracranial mass effect is outlined.
CLINICAL PRESENTATION
The patient presented with acute deterioration in conscious state and lateralizing signs from the mass effect of gas under tension. Two weeks earlier, he had experienced vague and subtle changes in personality noticeable only to his family.
INTERVENTION
The patient was cured by a frontal craniotomy, partial excision of the osteoma, and suture repair of the dural defect after evacuation of the pressurized air cavity.
CONCLUSION
This rare condition should be urgently treated in the event of acute deterioration. To prevent a life-threatening situation from arising, elective surgery should be considered for patients known to have air sinus osteomas that are at risk of erosion into the cranial cavity.

BACKGROUND
Osteoma of the paranasal sinuses is a rare and benign entity that develops slowly. If they occur, locations within the frontal sinus and ethmoid cells are more frequent, whereas osteomas in the sphenoid or maxillary sinus are very rare.
CASE
We report on a 25-year old female patient presenting with a bony mass in the right maxillary sinus. A standard external approach using a modified Caldwell-Luc procedure was successfully employed as endoscopic endonasal surgery was limited by the size of the bony lesion.
CONCLUSIONS
Trauma or infection are often suggested as an etiologic factor in the pathogenesis of osteoma. In our case the development of maxillary osteoma was related to dental extraction and postoperative fistula. External standard procedures remain mandatory if endonasal endoscopic surgery fails in the removal of osteoma of the paranasal sinuses.

Osteomas are benign mature bone tumors that typically arise in the skull. Osteomas larger than 3 cm in diameter are considered giant osteomas. Giant osteomas of the skull vault are very rare, especially in children; therefore, only a few cases have been reported in the literature. Although osteomas are usually asymptomatic, a large skull mass can cause headache, as well as esthetic disfigurement of the forehead. it can be misdiagnosed as other conditions, such as fibrous dysplasia, ossifying cephalhematoma, or other malignant bone tumors. Herein, the authors report 2 rare pediatric cases of giant osteomas mimicking fibrous dysplasia and their successful surgical excision. These cases showed good results without recurrence or complications on long-term follow-up after complete excision.

Review
Osteomas are rare benign tumors of bone commonly occurring in the maxillofacial skeleton. In the course of their slow but steady increase in size, osteomas of the maxillofacial bones remain asymptomatic until they attain sufficient sizes as to cause disfigurement and/or direct interference with the normal function of their anatomic location. Here, we report a case of a huge solitary peripheral osteoma of the lingual posterior mandible in a 50-year-old woman who was otherwise in good health. The patient reported at the dental clinic because the lesion interfered with speech, swallowing, and caused occasional gagging. Histological examination confirmed the clinical impression of a peripheral osteoma. Treatment was by surgical excision and histological examination. The patient remains free of recurrence after 5 years.

Review
Osteomas of the middle ear are rare benign neoplasms. To date, only a few cases have been reported. Osteomas of the middle ear are small, single, usually unilateral, peduncular growths, off-white in color, with a smooth or multilobular surface, asymptomatic or causing functional disorders. The most common symptom is conductive hearing loss because of impingement of the ossicular chain. Some cases are asymptomatic and are diagnosed incidentally. We present two cases of incidentally detected middle ear osteoma. Based on a review of the main articles in the literature and analysis of two cases managed in our department, we describe the clinical spectrum, etiology, and management of middle ear osteomas.

Review
Postacne osteoma cutis is a rare complication of acne vulgaris. If it occurs during a course of tetracycline or minocycline therapy, pigmented osteomas can occur as a result of tetracycline or minocycline bone complexes. We report a case of pigmented postacne osteoma cutis that developed after extensive acne surgery and a 2- to 3-month course of minocycline. Previously reported cases have been treated surgically, but our patient responded to 0.05% tretinoin cream, with transepidermal elimination of some osteomas.

Osteoma is a benign, slow-growing, painless, discrete lesion which is characterised with the proliferation of a compact or cancellous bone. Osteomas are rare on the jaws. Lesions of the mandible developed most often in the condyle, angle and margin. Osteoma developed on the genial tubercle area had only been reported in one case. A 50-year-old female patient has been admitted to our department with the symptom of a hard mass under the chin area. In extra-oral and radiographic examinations, a 1×1 cm size, round, palpable, immobile, radiopaque mass has been determined on the genial tubercle area. The lesion has been completely removed under local anaesthesia by extra-oral approach. Her recovery period was uneventful. Osteoma diagnosis was confirmed with histopathological examination. There is no recurrence at 3-year follow-up. The purpose of this case report is to present a peripheral osteoma case that occurred in the genial tubercle area which is an unusual place.
