OBJECTIVE The response characteristics of acoustically elicited vestibular evoked myogenic potentials (VEMPs) largely depend on the stimuli applied. A tone-burst stimulation of 500 Hz seems to be clinically most appropriate because those VEMPs can be elicited at the lowest stimulus intensity possible. The aim of the present paper was to describe normative(More)
OBJECTIVE To investigate safety and efficacy of a new transcutaneous bone conduction hearing implant, over a 3-month follow-up period. STUDY DESIGN Prospective, single-subject repeated-measures design in which each subject serves as his/her own control. SETTING Departments of Otolaryngology at 4 hospitals in Germany and Austria. PATIENTS Subjects were(More)
It is the aim of the present paper to correlate clinical symptoms of auditory dysfunction (tinnitus, hyperacusis, hearing loss) one year on average after a blunt trauma of the head with objective audiological test results (otoacoustic emission and auditory brainstem response testing, impedance audiometry) and to compare these findings to controls without(More)
Gap junctional coupling of cochlear supporting cells is thought to be responsible for spatial potassium buffering of the microenvironment of outer hair cells (OHC). OHC of the organ of Corti are considered as the target of aminoglycoside-induced ototoxicity. Due to the proposed functional relationship between OHC and cochlear supporting cells we(More)
The objective of this study was to investigate the occurrence of vestibular receptor deficiency and taste disorders after bilateral cochlear implantation in postlingually deafened patients and to find out whether the risk for these complications is higher for the second implantation. In a retrospective cohort study, we examined 20 patients (11-58 years,(More)
Rehabilitation strategies have been applied successfully over the last few decades to initiate central compensation of the tonus imbalance and to facilitate substitution in different types of peripheral vestibular dysfunction. However, these vestibular rehabilitation strategies are often not successful in patients with isolated otolith disorders. The aim of(More)
OBJECTIVES The aim of the present study was to investigate saccular function in patients with otosclerosis. Furthermore, the influence of stapedotomy on the vestibular-evoked myogenic potentials (VEMPs) should be demonstrated. STUDY DESIGN Prospective study. SETTING Tertiary referral center. METHODS Bone-conducted tone-burst-evoked VEMPs were measured(More)
Cochlear implant surgery has become a successful procedure for deaf patients to restore their hearing again. Some of the patients, however, complain of persisting dizziness after the surgery which can have a major impact on their quality of life. Neurotological tests of the vestibular system were applied in a total of 18 cochlear implantees pre- and(More)
Vestibular evoked myogenic potentials (VEMPs) can be recorded from sternocleidomastoid muscle (SCM) in clinical practice. The aim of the present study was to investigate VEMPs upon direct electrical stimulation of the human inferior vestibular nerve to evidence the vestibulocollic reflex arch and their saccular origin, respectively. Seven subjects were(More)
OBJECTIVE To compare the functional gain of different Symphonix Soundbridge audioprocessors (HF-processor and D-processor) to preoperatively fitted conventional hearing aids of patients with mild to severe sensorineural hearing loss in the high-frequency range. STUDY DESIGN In a prospective study, the Symphonix Soundbridge (HF-processor and D-processor)(More)
