Osteomas of the craniofacial region. Review of 106 cases

Abstract

BACKGROUND: Osteoma is a benign osteogenic lesion characterized by the proliferation of compact or cancellous bone. Although this tumour has a considerable incidence, there are few reports with large samples on this subject. OBJECTIVES: To describe clinical features of the osteomas in the craniomaxilofacial region. MATERIAL AND METHODS: Retrospective study of 106 patients diagnosed with 132 osteomas of the craniomaxilofacial region between 1986 and 2003. RESULTS: The mean age was 50 years. Osteomas were more frequent in men. Forty-nine per cent were of peripheral type, 29% central osteomas and 21% were located in the paranasal sinuses. Eighty-nine cases (84%) were operated and 80 patients were regularly followed up. Out of these, 73 did not recur. The seven recurrences were central osteomas. CONCLUSIONS: Osteomas usually appear in patients with more than 30-year old. Peripheral type showed the highest incidence among these lesions. Central and peripheral osteomas usually do not originate clinical symptoms whereas the ones located in paranasal sinuses can provoke headache and neuralgia/paresthesia.

“…Les ostéomes constituent des néoplasies bénignes relativement rares, caractérisées par une prolifération de tissu osseux spongieux et/ou compact [1,2]. Ils sont de trois types : périphériques, centraux ou extra-squelettiques [3,4].…”

Transoral Removal of Peripheral Osteoma at Sigmoid Notch of the Mandible

“…Peripheral osteomas, in most cases, are easy to recognize, on radiological imaging, a peripheral osteoma of the mandible is a classically well-circumscribed, round or oval, mushroom-like radiopaque mass with distinct borders [2,5,6]. The lesion may be sessile and attached to the cortical plates with a broad base or pedunculated with a narrow contact area between the lesion and the compact bone.…”

“…Surgical intervention is indicated only if it becomes large enough to cause facial asymmetry and functional impairment [2,5]. Surgical excision is usually simple in peripheral osteomas.…”
