RESUMEN
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.

The aim of this study is comparative assessment of of different bone-plastic materials for mastoidoplasty. The study included 30 patients who underwent 'canal wall down' mastoid surgery with mastoidoplasty. The following criteria were used for comparing: 1) simplicity of modeling of the material 2) the wound healing process 3) osteointegration - the process of formation of 'new bone' tissue (CT of temporal bones 6 and 12 months after oreretion). It was confirmed that the main groups of bone-plastic material (bioglass, composite materials and ß-tricalcium phosphate) is suitable for mastoidoplasty after 'canal wall down' mastoid surgery.
