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)
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)
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)
BACKGROUND Bone-anchored hearing aids provide a therapy option for patients with conductive and mixed hearing loss, with the possibility of audiological rehabilitation. Test rod and tension headband offer the patient a preoperative impression of their postoperative hearing. The aim of this study was to evaluate the tools available for preoperative(More)
OBJECTIVE To investigate the impact of different cochleostomy techniques on vestibular receptor integrity and vertigo after cochlear implantation. STUDY DESIGN Retrospective cohort study. SUBJECTS A total of 62 patients (17 to 84 years of age) underwent implantation via an anterior or round window insertion approach. METHODS Two groups of cochlear(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)
OBJECTIVE To evaluate patients after blunt trauma of the head, neck, and craniocervical junction (without fractures) with vertigo and to report the results of treatment after extensive diagnostics. STUDY DESIGN Prospective study of consecutive new cases with vertigo after trauma at different periods of onset. During 2000-2002, 63 patients were examined(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)
AIM Postoperative vertigo is a well-known complication after cochlear implantation. The aim of the study was to investigate whether the electrical stimulation of the auditory structures via cochlear implant electrodes can affect the vestibular system and induce vertigo. MATERIALS AND METHODS In the first group, 114 patients were surveyed retrospectively(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)
