Abstract. An abnormally large Jul 2, 2012 of a patient misdiagnosed with otosclerosis, who was subsequently found to have enlarged vestibular aqueduct syndrome bilaterally. Enlarged Vestibular Aqueducts and Childhood Hearing Loss. Vestibular Tags. General: hearing loss Enlarged vestibular aqueducts Pendred Syndrome.

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. Hearing loss is very likely. Diagnosis 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). Hearing loss or balance symptoms associated with an EVA can occur when the endolymphatic duct and sac expand to fill the larger space (see Figure).

There is a limited number of diagnostic procedures to verify the presence of large vestibular aqueduct syndrome (LVAS) in humans. The wideband absorbance (WBA) measurement technique is a non-invasive and objective tool for assessing the amount of sound energy absorbed by the tympanic membrane

the familial incidence of large vestibular aqueduct syndrome. (LVAS) detected siblings had bilateral large vestibular aqueducts and severe hearing loss [4].

When the endolymphatic duct and sac are larger than normal, as is the case in large vestibular aqueduct syndrome, endolymph is allowed to travel back from the endolymphatic sac into the inner ear.

Large vestibular aqueduct syndrome (LVAS) or enlarged vestibular aqueduct syndrome (EVAS) is a radiological diagnosis, which clinically manifests as sudden, fluctuating or progressive hearing loss.

Das Large vestibular aqueduct syndrome ist eine der häufigsten Ursachen für eine progrediente Schwerhörigkeit oder eine Ertaubung im Kindesalter. Die Prävalenz für das Large vestibular aqueduct syndrome wird bis auf 15% aller kindlichen sensorineuralen Schwerhörigkeiten geschätzt. If the vestibular aqueduct is larger in size, and the clinical presentation is consistent, the diagnosis can be made. Treatment is with mechanical hearing implants .

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. This is called an enlarged vestibular aqueduct, or EVA; the condition is also known as a dilated vestibular aqueduct or a large vestibular aqueduct.

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.

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.
