Osteoma in mandibular condyle

A Giant Osteoma of the Mandible

“…It has been considered to be a true neoplasm, developmental anomaly, or reactive lesion triggered by trauma muscle traction or infection [2,6,9]. Endocrine cause has been considered as a possible etiology [9,10]. Origin from embryonic cartilaginous rest or embryologic periosteum has also been reported [1,9,11].…”

“…Exostoses are commonly and erroneously termed osteoma [10,15]. However, exostoses such as tori are bony excrescences that occur on the buccal aspect of the alveolar bone [4].…”

A Study on Peri P Heral Osteomas of the Maxillofacial Region

“…It occurs due to proliferation of either compact or cancellous bone in an endosteal or periosteal location. In mandible bone, the lesions most frequently develop in the condyle, 5 lingual mandibular surface, 6 angle and margin. 5 The exact pathogenesis of the peripheral osteoma still remains unclear.…”

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.…”

“…Only one case of osteoma of sigmoid notch has been reported in English literature [5,6]. We report the second case of large peripheral osteoma originating from the sigmoid notch area of the mandible in a16-year-old female.…”
