OBJECTIVES Tinnitus is a well-known, difficult-to-treat symptom of hearing loss. Users of cochlear implants (CIs) have reported a reduction in tinnitus following implantation for bilateral severe-to-profound deafness. This study assessed the effect of electrical stimulation via a CI on tinnitus in subjects with unilateral deafness and ipsilateral tinnitus(More)
The aim of this clinical study was to assess speech recognition in noise after cochlear implantation in subjects with single-sided deafness and incapacitating tinnitus. 20 subjects complaining of severe intractable tinnitus unresponsive to treatment received a MED-EL cochlear implant (CI). 11 subjects had normal hearing (NH group) on the contralateral side,(More)
Seventeen adult subjects participated in a multicentre trial to compare the performance between an NRT-based MAP and their behavioural MAP. The NRT-based MAP was made using a correction factor to predict T/C levels, calculated from the difference between the ECAP threshold ('T-NRT') and the measured T/C levels at electrode 10, as described by Brown et al.(More)
This article provides a clinical step-by-step approach for assessing a patient with tinnitus as primary complaint. The medical diagnosis of the disease provoking the tinnitus has to be made first in a comprehensive evaluation, including imaging. The psycho-acoustic characteristics and the influence on health-related quality of life is a compulsory(More)
BACKGROUND Recently, a new speech coding strategy named 'fine structure processing' (FSP) has been launched. METHODS 32 subjects, all users of the MED-EL PULSARCI(100) system, have been switched over from a TEMPO+ to an OPUS 2 speech processor. In 22 subjects, the FSP strategy could be implemented (FSP group), in 10 patients not (high-definition(More)
OBJECTIVE Electric acoustic stimulation (EAS) is an increasingly popular means of treating individuals with a steeply sloping mid-to-high frequency hearing loss, who traditionally do not benefit from hearing instruments. These persons often have too much residual hearing to be considered for a cochlear implant. Several studies have demonstrated the ability(More)
In cochlear implants, the signal is filtered into different frequency bands and transmitted to electrodes along the cochlea. In this study the frequency-place function for electric hearing was investigated as a means to possibly improve speech coding by delivering information to the appropriate cochlear place. Fourteen subjects with functional hearing in(More)
OBJECTIVE Binaural interaction can be investigated using auditory evoked potentials. A binaural interaction component can be derived from the auditory brainstem response (ABR-BIC) and is considered evidence for binaural interaction at the level of the brainstem. Although click ABR-BIC has been investigated thoroughly, data on 500 Hz tone-burst (TB) ABR-BICs(More)
OBJECTIVE To compare audiometric and quality-of-life results in DFNA 9 patients who received a cochlear implant with cochlear implant patients with adult-onset progressive sensorineural hearing loss. STUDY DESIGN Prospective comparative design; results were collected cross-sectionally. SETTING Tertiary referral center. PATIENTS Eleven DFNA 9 patients(More)
OBJECTIVES describe the results of a retrospective study of cochlear implantation (CI) in seven subjects with Menière's disease. METHODOLOGY The subjects received either the Nucleus CI24RE(CA)/CI512 or the Advanced Bionics HiRes90K CI systems which use the ACE, MP3000, or HiRes S Fidelity 120 coding strategies. The audiometric measures included(More)
