Enlargement vestibular aqueduct

OBJECTIVE: To correlate clinical and audiometric findings with the radiologic appearance in patients with enlarged vestibular aqueduct.DESIGN A retrospective review of data from enlarged vestibular aqueduct patients identified in a pediatric hearing-impaired database of 1,200 patients.Vestibular dilation, or dilated vestibular aqueduct, is also called large vestibular aqueduct, enlarged vestibular aqueduct, or widened vestibular aqueduct.This long sounding name is given to a condition in which the certain structures within the inner ear become swollen and enlarged.

Some affected individuals also have an abnormally shaped cochlea, which is a snail-shaped structure in the inner ear that helps process sound.

Design: A retrospective review of data from enlarged vestibular aqueduct patients identified in a pediatric hearing-impaired database of 1,200 patients.

Large vestibular aqueduct syndrome can be characterized by delayed-onset, fluctuating.Enlarged vestibular aqueduct is the most common form of congenital inner ear abnormality seen on radiologic assesment.Scientists also are finding that 5 to 15 percent of children with sensorineural hearing loss (hearing loss caused by damage to sensory cells inside the cochlea) have EVA.

The human vestibular aqueduct (VA) shows great anatomical variations, and imaging can be difficult, so we need more data on the normal anatomy of the VA for better radiologic evaluation of large vestibular aqueduct syndrome (LVAS).The diagnosis can be made by high resolution CT or MRI, with comparison to the adjacent posterior semicircular canal.In addition to SNHL, patients have vestibular dysfunction, and characteristic temporal bone abnormalities (bilateral enlarged vestibular aqueduct with or without cochlear hypoplasia).Objective: To explore specific clinical issues, surgical results, and complications of 80 cochlear implantations (CI) in 55 patients with Pendred syndrome (PS) or non-syndromic enlarged vestibular aqueduct (NSEVA).Large vestibular aqueduct syndrome (LVAS), also known as large endolymphatic sac anomaly (LESA), refers to the presence of congenital sensorineural hearing loss with an enlarged vestibular aqueduct.

The vestibular aqueduct is a bony canal that connects the inner ear with the inside of the skull.Enlarged vestibular aqueduct size, HFPTA, and walking at a later age were correlated with abnormal vestibular test findings.Congenital conditions can also cause dizziness, including Arnold Chiari malformations, enlarged vestibular aqueduct, spasmodic torticollis, and cerebral palsy.Objective: To correlate clinical and audiometric findings with the radiologic appearance in patients with enlarged vestibular aqueduct.The Cincinnati criteria identified a large percentage of pediatric cochlear implant patients.OMIM: 53 DFNB4 with enlarged vestibular aqueduct is characterized by pre- or perilingual onset of sensorineural or mixed hearing loss, which may be fluctuating or progressive.

We review the correlation of phenotype with genotype of SLC26A4.Case series with comparison and a review of the literature. Methods. A retrospective study was performed.
