Endo-Orbital Osteoma: Two Case Reports

Abstract

Osteoma is a benign, slow-growing tumor, which mainly occurs in the bones and cavities of the middle third of the face, representing the most frequent benign tumor of the paranasal sinuses. Osteoma of the paranasal sinuses is generally asymptomatic and it is discovered only as a coincidental radiological finding; when it becomes symptomatic, the most common presenting symptoms are headaches and facial pain. Rarely the sinusal osteoma may entail secondary orbital extension, with ocular signs and symptoms. Primary intraorbital involvement is extremely rare. The authors present a review of the literature and report two cases of primary orbital osteoma. In both cases surgical treatment led to the complete remission of symptoms. Diagnosis and surgical therapy are discussed.

An unusual peripheral osteoma of the mandibular notch: a case report with computed tomography evaluation

“…Although osteomas can develop at any age, they seem to be more common among young adults [2,3,8,12]. Nevertheless, in other studies, higher frequencies of occurrence between the third and fifth decades were reported [7,11,13]. In agreement with this statement, our patient was in his fifth decade.…”

“…Radiographic findings usually describe osteomas as radiopaque masses with a density similar to that of bone [7,11]. Some authors [2,17] consider that CT, especially with 3D reconstruction, is the best imaging modality for a diagnosis of peripheral osteoma [7,11,13]. In our case, the osteoma was detected with panoramic and TMJ radiographs.…”

“…Traditional radiographic techniques are generally sufficient to diagnose osteomas [11,13]. Radiographic findings usually describe osteomas as radiopaque masses with a density similar to that of bone [7,11].…”

Peripheral osteoma of the maxillofacial region. Diagnosis and management: a study of 06 cases

“…Osteomas are the most frequent benign tumors of the paranasal sinuses, occurring most commonly in the frontal sinus. [10] Peripheral osteomas of the jaws are uncommon [9] and more often found in the mandible than in the maxilla [5]. Lingual aspect of the mandibular body and the inferior border of the angle are the most common sites affected in the mandible.…”

Rare case of primary orbital osteoma

“…Остеома нередко является случайной находкой: в 1% случаев при рентгенографии и в 3% -при ком-пьютерной томографии (КТ) околоносовых пазух [5] у пациентов в возрасте от 10 до 50 лет. Крайне редко остеомы выявляют у детей [6].…”
