The data of epidemiology, histological characteristics, MR and CT scans patterns in diagnosing are presented. All pathology of the IAC is divided into 2 large groups: 1) pathology arising from the structures of the IAC; 2) other pathology arising from the surrounding structures of the IAC (middle ear, middle or posterior cranial fosses). Special attention is paid to vestibular schwannoma, cholesteatoma, meningioma, paraganglioma, osteoma, lipochoristoma – IAC lesions identified in the clinical experience of the Otology and Skull Base Pathology Department of the Scientific and Clinical Center of Otorhinolaryngology; the surgical management and the results treatment will be presented in a separate clinical study.</p></abstract><trans-abstract xml:lang="ru"><p>В статье представлен анализ литературы, посвященной патологии внутреннего слухового прохода (ВСП); приведены данные эпидемиологии, гистологическая характеристика, МР- и КТ-паттерны, характерные для различного типа образований. Все патологии ВСП условно дифференцированы на 2 большие группы: 1) патологии, исходящие непосредственно из структур ВСП; 2) прочие патологии, разрушающие ВСП извне (пирамиды височной кости, средней и задней черепной ямок). Отдельное внимание уделено вестибулярной шванноме, холестеатоме, менингиоме, параганглиоме, остеоме, липохористоме – образованиям ВСП, выявленным в клиническом опыте отдела заболеваний уха и основания черепа ФГБУ «НКЦ оториноларингологии»; хирургическая тактика и результаты лечения будут приведены в отдельном клиническом исследовании.</p></trans-abstract><kwd-group xml:lang="en"><kwd>internal auditory canal</kwd><kwd>vestibular schwannoma</kwd><kwd>petrous pyramid cholesteatoma</kwd><kwd>meningioma</kwd><kwd>lipochoristoma</kwd><kwd>osteoma</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>внутренний слуховой проход</kwd><kwd>вестибулярная шваннома</kwd><kwd>холестеатома пирамиды</kwd><kwd>менингиома</kwd><kwd>липохористома</kwd><kwd>остеома</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Miyamoto RT, Althaus R, Wilson F, Brookler KH.
