OBJECTIVE To investigate whether the saccule exhibits temporary or permanent functional loss resembling threshold shifts in auditory brainstem response (ABR) of guinea pigs following noise exposure. DESIGN Randomly bred guinea pigs were divided into 3 groups: A (short-term noise exposure, 30 minutes, n = 15), B (long-term noise exposure, 40 hours, n = 9), and C (no noise exposure, n = 5). S...

Vestibular evoked myogenic potentials (VEMPs) are myogenic responses induced by stimulation of the saccular macula by intense sound stimuli. The responses are recordable from the sternocleidomastoid (SCM) muscles. We recorded VEMPs from normal subjects (up to three times in each subject) to identify: i) the best recording procedures, ii) the reliability, and iii) the normal limits for both indi...

It’s well known the noise effect relates to the hearing function while there are a very few studies connected to the vestibular disease. The aim of this study is to evaluate c-VEMPs responses in workers with noise induced hearing loss and exposed to noise in order to prove the possibility of damage in the vestibular via. We examined 60 workers with noise induced hearing loss and 30 office emplo...

R ecently, clinical vestibular tests have been developed for assessing otolith function. Little is known about treatment for otolith dysfunction, and this case report offers a perspective on using otolith stimulation to treat vestibular loss. A 62-year-old man underwent a left vestibu...

OBJECTIVES To investigate the clinical utility of VEMPs in patients suffering from unilateral vestibular schwannoma (VS) and to determine the optimal stimulation parameter (air conducted sound, bone conducted vibration) for evaluating the function of the vestibular nerve. METHODS Data were obtained in 63 patients with non-operated VS, and 20 patients operated on VS. Vestibular function was as...
