Enlarged vestibular aqueduct syndrome in the pediatric

It is one of the most common inner ear deformities which results in hearing loss during childhood.Ryan Marovich University of Pittsburgh Medical Center United States.Research suggests that most children with enlarged vestibular aqueducts (EVA) will develop some amount of hearing loss.

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).Background: Enlarged vestibular aqueduct (EVA) is the most commonly identified CT scan anomaly found in children with sensorineural hearing loss (SNHL).The vestibular aqueduct is a narrow, membrane lined channel in the petrous temporal bone through which endolymph drains from the membranous labyrinth of the inner ear to the endolymphatic sac.

Pendred syndrome - Genetics Home Reference - NIH

Large vestibular aqueduct, also known as enlarged vestibular aqueduct syndrome, is a syndromic form of hearing loss, caused by enlargement of the vestibular aqueduct in the inner ear.The combination of an enlarged vestibular aqueduct and an abnormally shaped cochlea is known as Mondini malformation.

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.To share our experience of cerebrospinal fluid gusher in cochlear implantation in patients with enlarged cochlear or vestibular aqueduct.

BACKGROUND AND PURPOSE: The size of vestibular aqueducts (VAs) seen on CT studies varies.Enlarged vestibular aqueduct Vestibular aqueduct enlargement, initially described by Valvassori and Clemis (1978), is the most common imaging abnormality in patients with congenital inner-ear defects (Irving and Jackler, 1997).Diagnosis of enlarged vestibular aqueduct (EVA) and theories of hearing loss, including audiologic presentation, progression of hearing loss and rehabilitative options. 15571 AudiologyOnline Article.

What is benign paroxysmal positional vertigo (BPPV)?

Objective: To correlate clinical and audiometric findings with the radiologic appearance in patients with enlarged vestibular aqueduct.

Enlarged Vestibular Aqueduct Syndrome in the Pediatric

The Cincinnati criteria identified a large percentage of pediatric cochlear implant patients.The aim of this study was to report three cases of LVAS encountered at the.

A large vestibular aqueduct (LVA) is the most common inner ear anomaly found on the imaging evaluation of children with sensorineural hearing loss (SNHL).Congenital conditions can also cause dizziness, including Arnold Chiari malformations, enlarged vestibular aqueduct, spasmodic torticollis, and cerebral palsy.

Part 2: Childhood Vestibular Disorders - KID PT

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).
