[Purpose] This study investigated to determine whether the Sideways Stepping Test (SST) is a useful test to detect unilateral vestibular hypofunction (UVH). [Subjects and Methods] Twenty-eight subjects including both male and females between the ages of 25 and 55 who had been diagnosed with UVH were recruited for the study. All the subjects were tested with the SST and followed by the head-shak...

We outline our routine approach to tinnitus patients, highlighting the different aspects of our examination: the clinical history, objective ear, nose, and throat and general examination, and audiovestibular testing. We emphasize the interest in testing not only the cochlear but the vestibular function of the inner ear. In our view, this testing is of paramount importance, for the cochleovestib...

So far it has only been possible to detect horizontal and vertical eye movements during real time; torsional eye movements have to be calculated from video-tape that have been processed several times, and each investigation takes considerable time. We developed a real time binocular infra red video eye tracker for routine clinical examination which allows real time graphical visualization of ho...

Our objective was to describe vestibular abnormalities in patients with relapsing and remitting multiple sclerosis. Thirty patients (6 men and 24 women) between 27 and 64 years of age underwent neurological and otolaryngological examinations, complete anamnesis, and electronystagmography. Patients with psychological or oculomotor paresis (or both), internuclear ophthalmoparesis, severe visual d...

The purpose of this report was to characterize the self-perceived balance disability/handicap of patients with bilateral reductions and bilateral complete losses of peripheral vestibular system function. Data from 72 patients whose electronystagmography and rotational examinations suggested normal, unilateral, or bilateral reductions in peripheral vestibular system function were used in the fir...

Schwannoma of the trigeminal nerve is a rare condition. Even rarer is hearing loss occurring as a result of this lesion. The aim of this study is to highlight this rare cause of hearing impairment. Here we report the clinical features and findings of the imaging and audiological investigations of a case of trigeminal schwannoma diagnosed at our institution. Our patient presented with headache, ...

UNLABELLED Benign Positional Paroxysmal Vertigo (BPPV) is one of the most common vestibular diseases and the active head rotation test one of the most modern methods of vestibular function assessment. AIM this study aims to verify if the active head rotation test may reveal signs of horizontal and/or vertical vestibulo-ocular reflex dysfunction in vertigo patients suspected for BPPV. STUDY ...

The aim of this work has been to analyze the modification of vestibular and optokinetic nystagmus in animals after administration of therapeutic doses of ketamine. Three healthy rabbits (two reds and one white), weighing between 2.5 and 3 kg, were submitted to electronystagmography recording. The rabbits, head blocked, were placed on a Tönnies rotatory chair in the middle of a rotatory cylindri...
