Surgical Labyrinthectomy of the Rat to Study the Vestibular System
Published on: May 19, 2018
Abstract:
Vestibular neurectomy technique used for the standard middle fossa approach and for a total translabyrithine VIII nerve section is described. The middle fossa approach has been used in 49 cases of mainly Meniere's disease and basically the same approach for nerve decompression has been used in 19 cases of facial paralysis, 15 being due to Bell's palsy, 2 to petrous pyramid cholesteatoma and 2 to facial nerve Schwannoma. In unilateral Meniere's disease with no further function in hearing, vestibular neurectomy gives good results in alleviating vertigo.

01:29The Vestibular System
The vestibular system is a set of inner ear structures that provide a sense of balance and spatial orientation. This system is comprised of structures within the labyrinth of the inner ear, including the cochlea and two otolith organs—the utricle and saccule. The labyrinth also contains three semicircular canals—superior, posterior, and horizontal—that are oriented on different planes.
01:15Equilibrium and Balance
The inner ear assumes dual functionalities of auditory perception and equilibrium maintenance. The vestibule is the organ responsible for balance. This organ contains mechanoreceptors, specifically hair cells, endowed with stereocilia, which aid in deciphering information regarding the position and motion of our heads. Two intrinsic components, the utricle and saccule, help perceive head position, while the semicircular canals track head movement. Neurological messages initiated in the...
