ABSTRACT
Enlarged vestibular aqueduct is an anomaly of the inner ear development, which is manifested by sensorineural hearing loss and vestibular disorders most often at an early age. It is not uncommon for this pathology to have a conductive component of hearing loss on audiometry. In such cases, the dilated vestibule syndrome masquerades as middle ear disease, particularly otosclerosis. There are several theories of the origin of the conductive component of hearing loss in this developmental anomaly, the main ones are discussed in this article. Multispiral computed tomography (MSCT) of temporal bones, which an otorhinolaryngologist should be able to evaluate independently, paying attention to all structures of the temporal bone, including an increase in the anteroposterior size of the vestibular aqueduct of more than 1.5 mm, allows detecting an enlarged vestibular aqueduct at the stage of preoperative examination of the patient. Timely detection of the enlarged vestibular aqueduct will allow avoiding unnecessary surgical intervention and associated complications in the form of gusher syndrome and vestibular disorders.
