[Enlarged vestibular aqueduct syndrome in patients with hypoacusis and deafness].
In 1978 Valvassori and Clemis have reported that enlarged vestibular aqueduct can cause progressive perceptive hearing loss and finally deafness.


OBJECTIVE
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.
