ABSTRACT
The article describes the results of examination of patients with otosclerosis before surgery on the medial wall of the tympanic cavity with conebeam computed tomography (CBCT). The following parameters were evelauated at the tomographic image: the width (internal and external) and the shape of the vestibule window niche, the presence or absence of the facial nerve canal and promontorium overhang, the distance from the stapes basis to the inner wall of the vestibule, the presence or absence of the round window ossification, the width of the round window. The data obtained by CBCT were compared with surgical data. Diagnostic sensitivity was 100%, specificity constituted 81%. Therefore, the conebeam tomography can be used in the diagnostic algorithm before planning of the tympanic cavity medial wall surgery.
