Fully Endoscopic Retrosigmoid
Vestibular Nerve Section for Refractory Meniere Disease.
Surgical interventions to the labyrinth or
vestibular nerve and intratympanic gentamicin application are out of option for this patient.
They also improved in measurements of pelvic floor muscle tone and
vestibular nerve fiber current perception threshold.
The article presents the outcomes of a study with betahistine in a previously established model of acute loss of vestibular function in cats following the unilateral sectioning of the
vestibular nerve. The immediate effect of this intervention is the loss of balance and the sensation of vertigo.
It affects the nerve responsible for balance (also called the
vestibular nerve).
The collective bundle of nerve cells that leaves the cochlea form the auditory nerve (cochlear and
vestibular nerve), which transmits those signals to the brain, where they are interpreted as sounds.
Anyway, oVEMP depend on the state of the upper part of the
vestibular nerve (16).
The word "intermedius" is used because of the intermediate position of the nerve between the superior part of the
vestibular nerve and the facial nerve (2).
Theoretically CVN contains cochlear and
vestibular nerve fibers, however with the present radiological investigations, it is not possible to determine the percentage of cochlear fibers within the CVN.
"Do we know what happens to the brain after you stimulate the
vestibular nerve for thirty or forty minutes a day for a couple months?
In both episodes, clinical signs and the findings in the vHIT provided sufficient data to localize the damage in the superior subdivision of the
vestibular nerve. The characteristics of the bony canal which harbors the nerve in its intratemporal portion render it highly susceptible to entrapment and ischemia in case of swelling due to viral infection [16].
