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)
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)
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)
Das Königsteiner Merkblatt (KM) in der 4. Aufl. (1996) bildet derzeit die Grundlage zur quantitativen Bestimmung des Hörvermögens und der resultierenden Minderung der Erwerbsfähigkeit (MdE) bei einer angezeigten beruflichen Lärmschwerhörigkeit. Die quantitative Bestimmung des Hörvermögens beruht auf ton- und sprachaudiometrischen Befunden in Ruhe. Jedoch(More)
This is a consensus statement on pediatric cochlear implantation by the European Bilateral Pediatric Cochlear Implant Forum. The consensus statement was determined by review of current scientific literature to identify areas of scientific and clinical agreement of current understanding of bilateral cochlear implantation. The statement is "Currently we feel(More)
The perception of speech of 167 children implanted with a CLARION Multi-Strategy Cochlear Implant (1.2 device) was evaluated preimplantation and at 3, 6, 12, 18, and 24 months postimplantation. The children were between 15 months and 15 years of age. The test materials consisted of 8 tests involving syllable structure, single- and 2-syllable words,(More)
BACKGROUND Damage to or functional impair of the inner hair cells, synapsis or dendrites of the ganglion cells of the auditory nerve result in specific audiometric findings. Due to the normal function of the outer hair cells otoacoustic emissions can be registered, ABR and ECochG show at least elevated thresholds or are absent. PATIENTS We demonstrate 5(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)
HYPOTHESIS Perimodiolar intracochlear electrodes with contacts facing towards the modiolus have limited current flow towards the outer wall of the cochlea and therefore, may reduce the occurrence of facial nerve stimulation (FN) in cochlear implant subjects. BACKGROUND Facial nerve stimulation is a well-known complication in cochlear implant treatment(More)
