Patterns of vestibular function following vestibular nerve section
The Laryngoscope, 1992AbstractBithermal caloric irrigations, low‐frequency rotational chair stimulation, and posturography were performed on 20 patients before and after vestibular nerve section. Twelve patients demonstrated acute postoperative spontaneous nystagmus and rotational vestibulo‐ocular reflex (VOR) asymmetry.

Bilateral Loss of Vestibular Function
Acta Oto-Laryngologica, 1995The clinical findings in 53 patients with bilateral vestibular failure (BVF) seen in a neurological hospital are reported. Bilateral acoustic neuromas were excluded. Seven patients (13%) had progressive cerebellar degeneration; these patients had no hearing complaints but showed gait ataxia, abnormal eye movements and cerebellar atrophy on neuro ...

Residual vestibular function after vestibular schwannoma surgery
Neurochirurgie, 2020This study aimed to assess vestibular function in 39 patients who underwent neurectomy for vestibular schwannoma.Semicircular canal reactivity was measured by video head-impulse test using high-frequency passive head acceleration. Response gain was calculated as a ratio between the areas under the eye-velocity curve and the head-velocity curve.Student ...

Investigation of vestibular function in patients with vestibular neuritis
Russian Bulletin of OtorhinolaryngologyVestibular neuritis occupies the third place in terms of prevalence in the structure of peripheral vestibulopathies, therefore, the choice of optimal diagnostic and differential diagnostic tactics at different stages of the disease is an urgent task. Objective.

Vestibular Training after Sudden Loss of Vestibular Functions
ORL, 201012 cases of unilateral labyrinthectomy, 3 cases of VIIIth nerve section, 22 cases of streptomycin sulfate infusion into the middle ear cavity and 8 cases of bilateral vestibular a-functions underwent vestibular training. Our training is very useful for regaining equilibrium and for evaluating the effects of training on equilibrium by recording the ...

Vestibular Function and Cochlear Implant
ORL, 1998The authors illustrate their personal experience relating to 32 patients, aged between 12 and 74 years, undergoing cochlear implant, in whom vestibular reflexes were evaluated before and after surgery. This series did not include cases of areflexia, but only 1 case of reduced vestibular reflexia consequently to surgery.

Vestibular Function in Auditory Neuropathy
Acta Oto-Laryngologica, 2000Auditory neuropathy is characterized by mild-to-moderate pure-tone hearing loss, poor speech discrimination out of proportion with this loss, absent or abnormal auditory brainstem responses and normal outer hair cell function as measured by otoacoustic emissions and cochlear microphonics.

Acta Oto-Laryngologica, 2000
Histamine has an excitatory action on rat medial vestibular nucleus neurones in vitro, an effect that is mediated by histamine H1 and H2 receptors. Betahistine, which is a weak agonist at the H1 receptor and a moderate antagonist at the presynaptic H3 autoreceptor, weakly excites medial vestibular nucleus cells but antagonizes their responses to ...

Components of vestibular cortical function
Behavioural Brain Research, 2013It is known that the functional response (e.g., nystagmus) to caloric vestibular stimulation is delayed and prolonged compared with the stimulus-response timing of other sensory systems. Imaging studies have used different models to predict cortical responses and to determine the areas of the brain that are involved.

Assessment of Vestibular Function by Videonystagmoscopy
Journal of Vestibular Research, 1995Videonystagmoscopy has been used to subjectively observe the responses of the vestibular system in a population of patients with vestibular deficits. These results were compared with those of a control group of healthy, age-matched volunteers. The videonystagmoscopy device is made of one or two CCD cameras mounted on lightproof goggles, allowing a ...
