This study aimed to compare the BAHA Attract and the first-generation Osia system after BAHA Attract to Osia conversion surgery. Method Five patients who had previously used the BAHA Attract system were converted to the first generation of the Osia system. Surgical aspects of the two different systems, audiological performance and subjective opinions of the patients were investigated. Pure tone audiometry and speech audiometry in quiet was performed with each patient's BAHA 5 sound processor on Attract, and the test battery was repeated six weeks after the Attract to Osia conversion and at different time points after the first fitting. Details of the surgery and patients' feedback were analysed. Results Audiology tests showed significant improvement when using either system; however, the Osia system performance was better. Based on patient feedback, all the five implantees preferred the Osia system. Con...

Recordings were obtained in 96% of these subjects with this standardised procedure. The group results are presented in terms of peak amplitude and latency, slope of the amplitude growth function and ECAP threshold. The effects of aetiological factors and the duration of deafness on the ECAP were also studied. While large intersubject variability and intrasubject variability (across electrodes) were found, results fell within a consistent pattern and a normative range of peak amplitudes and latencies was established. The aetiological factors had little effect on the ECAP characteristics. However, age affected ECAP amplitude and slope of the amplitude growth function significantly; i.e...

Binaural hearing forms the basis of the development of hearing-associated cortical networks in infants and toddlers, but simultaneous bilateral implantation is often postponed due to the demands of classical surgical methods, which are associated with large incisions and a deep bony well. The authors report on the use of a modern, thin implant type and the possibilities it provided to simplify the surgical technique. Recent models of the Cochlear™ Nucleus® implant family were studied in an international retrospective multi-center study: 6 otolaryngologists in 5 centers shared their experiences on 73 consecutively implanted, thin implants. The surgical incision could be made shorter than before and only shallow bony wells or none at all were created in 4 out of 5 centers. No complications occurred. This study underlines that implants with thin electron...

Preconditioning surgery was employed three months prior to the implantation procedure to ensure a sterile, dry protected environment for the electrodes. One month after implantation, the patient exhibited excellent auditory discrimination capability at the time of the first switch on. We suggest that some deaf/blind individuals may serve as very good candidates for intracochlear implantation.

We performed examinations on 20 healthy people with normal hearing. DPOAEs were recorded scanning the 0.5-6 kHz frequency interval before and after the exposures. We exposed the subjects to 0.5, 1, 2, 4 and 6 kHz pure tones and wide-band noise (intensity: 80 dB HL, duration: 3 minutes). We conclude that the amplitudes of DPOAEs changed immediately after exposures at most frequencies. DPOAE intensities decreased at some frequencies in the middle frequency range (1-2 kHz), and increased at low and particularly at high frequencies.

Successful intracochlear insertion of the 22 electrodes resulted in a 70 dB hearing improvement at frequencies 250-2000 HZ. Nevertheless, a characteristic facial twitching appeared upon activation of electrodes 9-13. Inactivation of these electrodes abolished the non-acoustic nerve excitation with preservation of acoustic performance. Osteogenesis imperfecta may involve a state of risk for non-acoustic nerve activation in cochlear implant patients possibly resulting from a reduced impedance to current spread by abnormal bone tissue. This, however can be overcome by simple programming manoeuvres.

Pre-operative electrical stimulation of the acoustic nerve, however, exhibited a good nerve function with no evidence of abnormal waveforms in the electroencephalogram (EEG). Successful intracochlear insertion of the 22 electrode resulted in a 40 dB hearing improvement at frequencies 250-2000 Hz in the implanted ear with no signs of pathologic wave activity at either the previously recognized epileptic focus (fronto-precentral region) or indeed, in other regions of the brain at use of the implant. We conclude that intracochlear implantation per se is not a hazardous intervention in patients with fronto-precentral epileptic foci.

The method is suited for monitoring the degeneration processes in Bell's palsy or other acute peripheral facial nerve pareses. The measurements permit estimating the duration of recovery and the probability of residual signs. The method helps the indication and timing of decompression surgery. In spite of certain difficulties involved in the procedure, its introduction into the diagnostics of facial nerve diseases is recommended.

We applied cardiovascular reflex tests for assessment of autonomic neuropathy. The aim of our investigation was to compare the BAEP results of this patient group with those of controls and to look for the possible correlation between alteration of the auditory brainstem function and cardiovascular autonomic neuropathy. Analysis of the latencies (waves I, II, III, and V) and the interpeak latencies (I-III and I-V) of BAEP revealed a significant difference between those of diabetics and those of healthy controls. The amplitudes of waves I, III, and V were definitely lower in comparison with amplitudes of healthy controls. We observed a positive correlation between the overall autonomic score and the latencies (waves III and V) and interpeak latencies (I-III, I-V). These data support the hypothesis that long-standing diabetes mellitus and diabetic neuropathy ...
