[Mastoid osteoma]

Osteomas of the temporal bone are rare, especially osteomas originating from the mastoid process. Most often occur in women aged 20-30 years. The maximum growth rate is observed during puberty. Usually, the neoplasm becomes an accidental finding on X-rays or CT scans. The clinic of osteoma depends on its location and size. The patient may complain of a cosmetic defect, headache, discomfort and a feeling of heaviness in the area of the neoplasm. In this clinical case, a long-term asymptomatic course of osteoma of the temporal bone is described. CT examination was used for its visualization, and treatment was carried out surgically using a drill.
