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

Enlarged Vestibular Aqueduct Syndrome (LVAS) is a puzzle to all; the parents, the audiologists, the educators, and certainly the child growing up with fluctuating Large vestibular aqueduct syndrome and stapes fixation. A. SHIRAZI, M.D., J. E. FENTON, F.R.C.S.I., P. A. FAGAN, F.R.A.C.S.. Abstract. An abnormally large Jul 2, 2012 of a patient misdiagnosed with otosclerosis, who was subsequently found to have enlarged vestibular aqueduct syndrome bilaterally.

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. This often results fluctuations in hearing levels. aqueduct was evaluated. Within this group of 5366 ears, forty-seven ears (1%) in twenty-six patients demonstrated a large vestibular aqueduct (diameter greater than 1.5 mm). A review of the relevant embryology, anatomy, and physiology is reported. A discussion of hypocycloidal polytomography and computed tomography of Large Vestibular Aqueduct Syndrome (LVAS) is one of a group of deformities that results from this abnormal or delayed development of the inner ear.

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.

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 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.

EVA is the most common inner ear malformation associated with sensory hearing loss, and is detected with a CT scan. One significant cause of progressive hearing loss is the congenital enlargement of the cochlear aqueducts. This condition is referred to as large vestibular aqueduct (LVA) syndrome, also known as enlarged or dilated vestibular aqueduct syndrome. Recently, enlargement of the vestibular aqueducts as the sole radiographically detectable inner ear anomaly has been recognized as a distinct pattern of congenital inner ear malformation. Pathogenesis of the large vestibular aqueduct syndrome probably stems from an early derangement in the embryogenesis of the endolymphatic duct.

Large vestibular aqueduct syndrome is characterized as bony canals in the inner ear extending into the brain.

EVA is the most common inner ear malformation associated with sensory hearing loss, and is detected with a CT scan. This is called an enlarged vestibular aqueduct, or EVA; the condition is also known as a dilated vestibular aqueduct or a large vestibular aqueduct.
