This is called an enlarged vestibular aqueduct, or EVA; the condition is also known as a dilated vestibular aqueduct or a large vestibular aqueduct. If a vestibular aqueduct is enlarged, the endolymphatic duct and sac usually grow large too. The functions of the endolymphatic duct and sac are not completely understood.

The size of the aqueduct ranged from 1.5 to 8 mm. in the anteroposterior diameter; the clinical incidence is 50 in 3700 consecutive cases referred for inner ear tomography. Bilateral involvement is twice as common as unilateral with a female to male predominance of 3:2. Most cases are associated with congenital hearing losses.

Large vestibular aqueduct syndrome (LVAS) is thought to be one of the most common congenital causes of sensorineural hearing loss (SNHL). It is usually sudden after head trauma or progressive during childhood. Cochlear implantation is the surgical effective choice of LVAS if marked hearing loss occurred. 1 article features images from this case

If a vestibular aqueduct is enlarged, A vestibular aqueduct is a small, bony canal with the temporal bone of the skull (behind the ear) that connects the inner ear to a nearby balloon-shaped structure called the endolymphatic sac. The inner ear structures consist of separate hearing and balance organs, known as the cochlea and vestibular apparatus, respectively.

Recently, enlargement of the vestibular aqueducts as the sole radiographically detectable inner ear anomaly has been recognized as a distinct pattern of congenital inner ear malformation. Pathogenesis of the large vestibular aqueduct syndrome probably stems from an early derangement in the embryogenesis of the endolymphatic duct. Large vestibular aqueduct syndrome (LVAS), also known as enlarged vestibular aqueduct (EVA) or large endolymphatic sac anomaly (LESA), refers to the presence of congenital sensorineural hearing loss with an enlarged vestibular aqueduct due to enlargement of the endolymphatic duct. Enlarged vestibular aqueducts can be bilateral or unilateral. Hearing loss caused by large vestibular aqueduct syndrome is not inevitable, although people with the syndrome are at a much higher risk of developing hearing loss than the general population.

One significant cause of progressive hearing loss is the congenital enlargement of the cochlear aqueducts. This condition is referred to as large vestibular aqueduct (LVA) syndrome, also known as enlarged or dilated vestibular aqueduct syndrome.

Large vestibular aqueduct syndrome is characterized as bony canals in the inner ear extending into the brain.
