Large Vestibular Aqueduct Syndrome is a congenital malformation of the temporal bone characterised by early onset of sensorineural hearing loss and vestibular disturbance.
Materials and methods. Seventeen patients affected with large vestibular aqueduct syndrome (LVAS), diagnosed by means of high-resolution magnetic resonance imaging of the inner ear, with 3-dimensional reconstructions of the labyrinth and by high-resolution spiral computed tomography of the temporal bone, performed only on the oldest patients, have been submitted to a complete audiological
diameter) vestibular aqueduct, are analyzed. In addition to the aqueduct other associated inner ear anomalies have been identified in 60% of this population including: enlarged vestibule (14); enlarged vestibule and lateral semicircular canal (7); enlarged vestibule and hypoplastic cochlea (4); and Enlarged Vestibular Aqueduct Syndrome (EVAS) Also known as Large Vestibular Aqueduct Syndrome, EVAS is a non-congenital, syndromic form of hearing loss caused by an enlarged vestibular aqueduct*, usually with a diameter larger than 1.5mm (Valvassori & Clemis, 1978). In EVAS, the endolymphatic duct and sac are also enlarged (see Figure 1), which a large vestibular aqueduct is a temporal bone dysplasia that is a variant of the Mondini type of deformity and that the associated hearing loss is congenital in nature. Our clinical observations, how-ever, indicate that the hearing loss in children with an isolated enlargement of the vestibular aqueductis acquired during childhood. The natural This paper presents the second case in the literature of large vestibular aqueduct syndrome without associated cochlear anomalies in 2 members of the same family. The syndrome is frequently associated with sensorineural hearing loss presenting in childhood. The onset is commonly sudden, following an event causing increased intracranial pressure.
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). When Inner ear Vestibular Aqueduct Radiological studies, ordered due to the mixed component and decreased hearing sensitivity, revealed large vestibular aqueduct syndrome (LVAS). Based on the diagnosis of LVAS, a cochlear implant Large Vestibular Aqueduct Syndrome is a congenital malformation of the temporal bone characterised by early onset of sensorineural hearing loss and vestibular disturbance. Large vestibular aqueduct syndrome (LVAS) is an uncommon disorder that manifest as progressive sensorineural hearing loss starting in infancy, early childhood and less commonly in adolescence. We report an 18-year-old girl who had enlarged vestibular aqueduct (VA) on computed tomography (CT) and magnetic resonance (MR) imaging.

Missbildningar 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. When a vestibular aqueduct is larger than normal (>1.0-1.5 mm), it is known as a large vestibular aqueduct (LVA) or by the term used here, enlarged vestibular aqueduct (EVA). EVA is the most common inner ear malformation associated with sensory hearing loss, and is detected with a CT scan.

Studies show that genetic Summary. Enlarged Vestibular Aqueduct Syndrome is characterized by a widening of the vestibular aqueduct, associated with sensorineural hearing loss, or The enlarged vestibular aqueduct syndrome is one of the most common causes of congenital sensorineural hearing loss. It is manifested as enlargement of the Jan 2, 2021 Normally, the vestibular aqueduct is very narrow: halfway along its length, it is less than 1 millimeter (mm) across—about the width of a pin. But Jan 22, 1999 A large vestibular aqueduct is one of the commonest radiological abnormalities of the inner ear.

The radiographic observation of 50 patients, each having an enlarged (greater than 1.5 mm. diameter) vestibular aqueduct, are analyzed. In addition to the aqueduct other associated inner ear anomalies have been identified in 60% of this population including: enlarged vestibule (14); enlarged vestibule and lateral semicircular canal (7); enlarged vestibule and hypoplastic cochlea (4); and Enlarged Vestibular Aqueduct Syndrome (EVAS) Also known as Large Vestibular Aqueduct Syndrome, EVAS is a non-congenital, syndromic form of hearing loss caused by an enlarged vestibular aqueduct*, usually with a diameter larger than 1.5mm (Valvassori & Clemis, 1978).

The large vestibular aqueduct as an isolated anomaly of the temporal bone has been previously identified radiologically, and its association with sensory neur. Enlarged vestibular aqueduct syndrome is often comorbid with other inner ear development problems, such as cochlear deformities.
