Large vestibular aqueduct syndrome (LVAS) - A guide to Hearing Loss This long sounding name is given to a condition in which the certain structures within the inner ear become swollen and enlarged. This can result in fluid flowing back into these structures which causes hearing loss.

A 12-year-old boy with large vestibular aqueduct syndrome presented with significant hearing loss following head trauma. He was treated with steroids and hyperbaric oxygen therapy, with good improvement of hearing thresholds on audiography.

Because the syndrome lacks unique char-acteristics, it may be undetected or not diagnosed until adulthood.

The large vestibular aqueduct (LVA) is reported to be the most common inner ear anomaly identified on computed tomograms (CTs) in children with sensorineural hearing impairment (SNHI). 1 As such, hearing impairment is frequently attributed to the presence of an LVA. 2 The description of LVA syndrome in 1978, which included associated inner ear anomalies, 3 led to an interest in the LVA as an Large vestibular aqueduct syndrome First described by Valvassori and Clemis in 1978 50 cases out of 3,700 tomograms, or 1.4% congenital hearing loss and vestibular symptoms enlarged vestibular aqueducts from 1.5– 8.0 mm 50% of the individuals with LVA were children and teenagers female to male ratio was 3:2 Large vestibular aqueduct syndrome is characterized as bony canals in the inner ear extending into the brain.

Discussion. Endolymphatic hydrops and large vestibular aqueduct syndrome have in general been considered to be separate, unrelated entities, and some authors have suggested that it is ‘doubtful that endolymphatic hydrops plays a role in the SNHL of large vestibular aqueduct syndrome’.

All prior studies have reported some anomalies associated with LVAS by imaging techniques. 2005-11-01 · The large vestibular aqueduct syndrome (LVAS) is characterized by the presence of an abnormally large vestibular aqueduct (LVA) generally associated with fluctuating, progressive sensorineural hearing loss (SNHL), often with sudden, stepwise onset or progression secondary to activities involving minor head trauma, large sudden shifts of barometric pressure, the Valsalva maneuver, and so forth,,,,,,,,,,. Large vestibular aqueduct syndrome (LVAS) - A guide to Hearing Loss This long sounding name is given to a condition in which the certain structures within the inner ear become swollen and enlarged. This can result in fluid flowing back into these structures which causes hearing loss. Large Vestibular Aqueduct Syndrome: A Case Study Author: American Academy of Audiology Created Date: 2/18/2006 3:00:49 PM Patho‐genesis of the large vestibular aqueduct syndrome probably stems from an early derangement in the embryogenesis of the endolymphatic duct. This anomaly appears to be relatively common in children with sensorineural hearing loss and is probably significantly underdiagnosed. Se hela listan på asha.org The size of the aqueduct ranged from 1.5 to 8 mm.

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 When a vestibular aqueduct is larger than normal, it is known as a large vestibular aqueduct (LVA) or by the term used here, enlarged vestibular aqueduct (EVA).

the term "large vestibular aqueduct syndrome" (LVAS) (Phelps, 1996). Jackler and De La Cruz (1989) have stated that LVAS should be diag-nosed when a LVA is the only "anomaly of the inner ear evident on radiographic studies." The prevalence of an enlarged vestibular aqueduct is thought to be relatively uncommon. Recent studies indicate that a vestibular aqueduct is abnormally enlarged if it is larger than one millimeter, roughly the size of the head of a pin.
