Osteoma of the temporal bone is an unusual benign slow-growing tumour composed of mature lamellar bone. It is a single pedunculated mass that often occurs unilaterally. Osteomas of external auditory canal are more common than in the other parts of temporal bone. Clinical presentation includes ear pain, hearing loss, tinnitus or vertigo. More often these lesions are an incidental finding during radiographic evaluation. Surgical excision of the osteoma is preferred in cases with impending complications. Here, we report a 36-year-old woman who came with problems of ear discharge, ear pain, hearing loss and occasional bleeding from the ear. She was diagnosed with osteoma of temporal bone with erosion of lateral semicircular canal and facial canal. Osteoma was excised and the defective areas were reconstructed.

“…Differential diagnosis include exostosis in case of external auditory canal osteomas and Paget’s disease, osteosarcoma, osteoblastic mestastais, eosinophilic granuloma, giant cell tumour, fibrous dyplasia, calcified meningioma in case of mastoid osteoma 7. Paget’s can be distinguished radiologically with its coarsened trabecular pattern.…”

Osteomas are osteoblastic neoplasms affecting the parietal and frontal bone. Mastoid osteomas of temporal bone are rare benign tumors with incidence of 0.1%-1% of all benign tumors of the skull.We present a case of a young 19-year-old female who complained of right posterior auricular hard swelling which had gradually increased in size over the past 2 years and felt pain for less than a year.There was no history of trauma, symptoms of inflammation or occlusion of the ear canal. She felt a pain during the eruption of her second molar teeth. Non-contrast CT was done and it showed a well-defined densely calcified lesion of bone attenuation in the right mastoid posteriorly measuring 1.7 × 1 × 2.3 cm. The middle ear cavity, ossicular chain, inner table of skull and diploe were normal with no extension intracranially and no bony destruction.These findings spoke in favor of a mastoid osteoma.

“…8,9 Various aetiologies include genetic origin, trauma, surgery, radiotherapy, chronic infection and pituitary dysfunction. 10 Histologically three subtypes are identifiedcompact osteoma, spongiotic osteoma and mixed osteoma. Compact osteoma has haversian system and it is dense, sclerotic and round in shape.…”

<p class="keywords">Osteomas are benign slow growing tumors of mesenchymal origin. Most commonly found along the long bones like proximal shaft of femur around 19% followed by tibia around 10% and head and neck osteomas around 0.1 to 1%. We report a rare case of postaural osteoma in a 44 year old female with cosmetic deformity and discuss its differential diagnoses and treatment protocol. A 44-year-old female presented to ear, nose and throat (ENT) outpatient department (OPD) with complaints of swelling in the left postaural region since 25 years gradually increasing in size. On examination, there was a single swelling in the left post aural region measuring about 4×5×3 (cms) hard in consistency and non-tender. Non contrast computerized tomography (CT) of temporal bone showed well defined extracranial dense sclerotic bony lesion arising from mastoid part of left temporal bone likely osteoma. Patient planned for excision and histopathological examination was consistent with osteoma.<strong> </strong>In conclusion, though osteoma in mastoid bone is a very rare possibility still it should be kept in consideration in the list of differential diagnoses of the tumors of temporal bone. We highlight the need for a careful clinical evaluation supported by radiologic and histopathological investigations which will help in the diagnosis, resulting in better prognosis.</p>
