lateral portions of the superior vestibular, inferior vestibular, and the singular nerves and their bony channels lateral to the internal auditory canal were made.

Our team compared CT scans of the patients’ vestibular structures and added evidence gathered from 1,000 slides made from preserved bones of the inner ear. What we realized was that we were looking at a balance disorder caused by holes in the uppermost canal of the vestibular structure, the loop known as the superior canal.

The semicircular canals are three canals used to provide information to the brain on directional balance. Each canal is lined with cilia and filled with fluid. As the 

It affects the horizontal canal in 10 to 20% of cases and the superior (top, also called anterior) canal in 3%. BPPV affects about 2.5% of people at some point in their lives. The vestibular systems of lampreys contain two semicircular canals while those of hagfish contain a single canal.

Present in otolith (calcium carbonate crystals) organs – saccule (anteriorly) and utricle (posteriorly) Both are connected by corresponding ducts, which together will form endolymphatic duct, this passes through a bony canal (the vestibular aqueduct), and expands into flattened endolymphatic sac, blending into posterior cranial fossa dura.

SUMMARY: Third window abnormalities are defects in the integrity of the bony structure of the inner ear, classically producing sound-/pressure-induced vertigo (Tullio and Hennebert signs) and/or a low-frequency air-bone gap by audiometry. Specific anatomic defects include semicircular canal dehiscence, perilabyrinthine fistula, enlarged vestibular aqueduct, dehiscence of the scala vestibuli This test observes the superior vestibular nerve through the lateral semi-circular canal. Treatment for Acoustic Neuromas (Vestibular Schwannomas) Acoustic Neuroma treatment depends on your age, general health, hearing status, tumor size, and how are the symptoms affecting you and your health.
