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)
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)
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 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)
Hintergrund und Fragestellung. Bei der Versorgung von frontobasalen Defekten stehen eine Vielzahl von Transplantaten zur Verfügung. Ein potentielles Infektionsrisiko autologer Transplantate macht ein homologes Material sinnvoll. Patienten/Methodik.

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)
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)
In the mammalian cochlea, tight junctional strands are visible on freeze fracture images of marginal cells and other inner ear epithelia. The molecular composition of the strial tight junctions is, however, largely unknown. We investigated the expression of integral tight junction-proteins, claudin-1 to -4, and occludin, in stria vascularis of the(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)
