vestibular 1. pertaining to any pertaining to the vestibular organ.
There is no agreement in the literature as to the most frequent abnormality in the ear in patients with Pendred syndrome. Cochlear defect described as "Mondini malformation" was cited as an almost constant finding in a radiologic study performed with conventional tomography ( 6 ).

If you or your child is experiencing progressive hearing loss, one of the conditions you may be checked for is Enlarged Vestibular Aqueduct Syndrome. Basically, it means that the channel connecting the inner ear and a cranial space has become larger than normal.

Abstract We report the case of a 14-year-old girl with a large vestibular aqueduct (LVA) in whom hyperbaric oxygen (HBO) therapy was effective for the treatment of sensorineural hearing loss. The patient was referred to Nagoya University Hospital for the treatment of hearing loss on 14 September, 1998, because her right hearing level had declined abruptly on 22 August, 1998, and had not changed for 3 weeks since then in spite of steroid and prostaglandin therapy.

Four patients with large vestibular aqueduct syndrome were included in this study. Three of the patients underwent endolymphatic sac closure surgery in the ear with worse hearing.

What is Pendred syndrome? Pendred syndrome is a genetic disorder that causes early hearing loss in children.

Pure tone audiometry, multifrequency tympanometry, audiometric Bing testing, and magnetic resonance imaging (MRI) were performed in patients with large vestibular aqueduct (LVA) syndrome. The air–bone gap always existed.
Pendred syndrome is a autosomal recessive disease, classically characterized by congenital sensorineural hearing loss, goiter and iodine organification defect. The chromosomal region, 7q31(PDS gene), was identified as this syndrome locus in 1998.
Background: Enlarged Vestibular Aqueduct Syndrome (MIM 603545) is the most common form of congenital inner ear abnormality seen in radiological assessment, associated with sensorineural hearing impairment or syndromic forms of deafness such as Pendred syndrome (MIM 274600), an autosomal-recessive disorder, is characterized additional with thyroid dysfunction which may leads to goiter. Up to now only mutations in the SLC26A4 gene, located on Chromosome 7q31, have been made responsible for Pendred- and Enlarged Vestibular Aqueduct syndrome.

Medical Central Resource Bilateral Large Vestibular Aqueduct Syndrome David White 4/10/97 Presentation 13 year old female with sensorineural hearing loss. Imaging Technique CT MRI Imaging Findings CT: There is enlargement of the bilateral vestibular aqueducts (5 mm's) MR: There is enlargement of the bilateral endolymphatic ducts and sacs.
At the hinder part of the medial wall of the vestibule is the orifice of the vestibular aqueduct , which extends to the posterior surface of the petrous portion of the temporal bone . It transmits a small vein , and contains a tubular prolongation of the membranous labyrinth , the ductus endolymphaticus , which ends in a cul-de-sac between the layers of the dura mater within the cranial cavity .
Mondini Malformation and Vestibular Aqueduct Syndrome Findings: Axial CT of the right temporal bone shows a globular appearing cochlea and a markedly dilated vestibular aqueduct. Discussion: Mondini malformation is the term often used to describe any inner ear dysplasia, but more precisely it refers to lack of normal 2.5 turns of the cochlea.
