BACKGROUND In Germany the guideline for the hearing loss quantification and the resulting assessment of the reduction in earning capacity is the Königsteiner Merkblatt (KM). The quantification depends on the results of the tone and speech audiogram in silence. However, speech discrimination tests in noise may provide additional information about the(More)
OBJECTIVE Evaluation of auditory performance and its evolution over time in patients with the auditory brainstem implant. STUDY DESIGN Prospective study. SETTING Tertiary referral center. PATIENTS AND METHODS Between May 1996 and April 2000, 14 patients with neurofibromatosis type 2 underwent implantation with a multichannel auditory brainstem(More)
UNLABELLED OBJECTIVE The purpose of this study was to present the patients' recommendations and judgments about their hearing and communication abilities with the help of the auditory brainstem implant. STUDY DESIGN Prospective study. SETTING Tertiary referral center. PATIENTS AND METHODS This evaluation was based on the data obtained by the(More)
HYPOTHESIS To explore, from the payers' perspective, the cost-benefit ratio of pediatric cochlear implantation for congenitally deaf and prelingually deafened children compared with children with hearing aids. The study should verify the hypothesis that educational and associated costs increase with age at implantation and that these can be below costs for(More)
Today, cochlear implantation is the treatment of choice in the case of severe to profound hearing loss, but the speech perception abilities of many recipients in noisy conditions are still poor and the overall sound quality and ease of listening still require improvement. Residual low-frequency hearing has been associated with improved hearing performance(More)
OBJECTIVE This study aimed to determine the maximum dose of radiation the CLARION 1.2 cochlear implant can withstand safely. INTRODUCTION Cochlear implants restore functional hearing to patients with sensorineural deafness. Because some patients may need radiation therapy, it is important to investigate the influence of ionizing radiation on cochlear(More)
OBJECTIVE In subjects who are deaf and who also have tinnitus in the affected ear, tinnitus treatments based on acoustic input are impossible. On the other hand, tinnitus suppression using electric stimulation has been reported to be successful. Therefore, a study was initiated to investigate the potential of cochlear implantation (CI) in unilateral deaf(More)
Mutations in the GJB2 gene are known to represent the commonest cause of hereditary and congenital hearing loss. In this study, a complete sequencing of the GJB2 gene in a cohort of 506 patients from a single, large cochlear implant program in Europe was performed. Audiological testing for those patients who could actively participate was performed using(More)
OBJECTIVES In recent years, it has been possible to preserve hearing after cochlear implantation in patients with significant amounts of low-frequency residual hearing. Due to the dimensions and characteristics of the cochlear implants (CIs) Nucleus® Hybrid™-L24 and Nucleus Freedom™ CI422, both can be used to preserve residual hearing. The aim was to(More)
OBJECTIVES/HYPOTHESIS To evaluate the influence of the introduction of newborn hearing screening programs on the age at cochlear implantation in children. STUDY DESIGN Retrospective, multicenter cohort study. METHODS All 1,299 pediatric cochlear implant users who received their implants before the age of 5 years between 1995 and 2011 in the Medical(More)
