Unlabelled: In 1978 Valvassori and Clemis have reported that enlarged vestibular aqueduct can cause progressive perceptive hearing loss and finally deafness.
Aim: Analysis of CT scans of patients with cochlear implants. Analysis of radiological data of 120 implanted patients was performed. CT examinations were performed during qualification to cochlear implantation. Most of the CT scans were performed using high resolution computed tomography (HRCT). A special attention was paid to patients with progressive perceptive hearing loss and CT of two patients with "gusher" during CI surgery. In one case (6-years old girl with bilateral profound perceptive hearing loss diagnosed in 2nd year of age) an enlarged vestibular aqueduct was found radiologically. In the second case (16 years old girl with progressive perceptive hearing loss since 1st year of age) no enlarged vestibular aqueduct was detected. Diagnostics and treatment of enlarged vestibular aqueduct syndrome are presented.

Purpose: To explore how hearing changes over time and the characteristics associated with progressive hearing loss in children with enlarged vestibular aqueduct (EVA), and develop a prediction model for anticipation of hearing progression probability.
Methods: A retrospective analysis was conducted on 48 children (92 ears) diagnosed with EVA. A total of 314 audiograms were included in the analysis of hearing loss trajectories using linear mixed-effects model.
[Effects of cochlear implantation on vestibular function in patients with large vestibular aqueduct syndrome].

This study aimed to compare the effects of cochlear implantation（CI） on vestibular function in patients with large vestibular aqueduct syndrome（LVAS） and in patients with extremely severe deafness with normal inner ear structure. A total of 28 LVAS patients and 28 patients with normal inner ear structure who suffered from extremely severe deafness were selected. The parameters of caloric tests, bone conduction evoked cervical vestibular-evoked myogenic potentials（cVEMP）, bone conduction evoked ocular vestibular-evoked myogenic potentials（oVEMP） and video head impulse tests（v-HIT） were compared between the two groups before and after CI.

Objectives: Surgical treatments for Ménière's disease differ in efficacy. Endolymphatic duct blockage (EDB) is favored for its minimal risk and ability to preserve hearing. One of the main challenges in the technique is the difficulty in accurately identifying the endolymphatic duct (ED).
