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.

Large vestibular aqueduct syndrome






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.

In 1861, a French physician, Prosper Meniere, presented a paper in which he described a triad of symptoms compromising episodic vertigo, hearing loss, and tinnitus33. 2001 (Engelska)Ingår i: Neuroradiology,2001, 2001, s. 81-81Konferensbidrag, Publicerat paper (Refereegranskat).

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). When Inner ear Vestibular Aqueduct

LVAS is not congenital like doctors originally thought. They now know it occurs sometime after birth and is the result of abnormal postnatal or early childhood development.

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 (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.
