INTRODUCTION More than 3,000 patients have received a cochlear implant in Hannover. METHODS A group of 864 patients was selected from the main group for the analysis of speech perception development. Depending on the term of introduction of new implant technology, the viewed group was divided into 5 subgroups. RESULTS The test battery during regular(More)
The cochlear implant can restore speech perception in patients with sensorineural hearing loss. However, it is ineffective for those without an implantable cochlea or a functional auditory nerve. These patients can be implanted with the auditory brainstem implant (ABI), which stimulates the surface of the cochlear nucleus. Unfortunately, the ABI has(More)
CONCLUSION The CustomSoundEP software can record ECAP traces in an automated manner and calculate the ECAP threshold from them. These values are in good agreement with those determined by audiologists. Manual optimization measurements, as needed when using the predecessor version 3 of the software, are done by the software itself in the newer system. (More)
A topographical representation for frequency has been identified throughout the auditory brain in animals but with limited evidence in humans. Using a midbrain implant, we identified an ordering of pitch percepts for electrical stimulation of sites across the human inferior colliculus (IC) that was consistent with the IC tonotopy shown in animals. Low(More)
OBJECTIVES/HYPOTHESIS To evaluate the effect of technological advances in the past 20 years on the hearing performance of a large cohort of adult cochlear implant (CI) patients. STUDY DESIGN Individual, retrospective, cohort study. METHODS According to technological developments in electrode design and speech-processing strategies, we defined five(More)
OBJECTIVES/HYPOTHESIS To evaluate the role of gender on the hearing performance of postlingually deafened adult patients with cochlear implants. STUDY DESIGN Individual retrospective cohort study. METHODS There were 638 postlingually deafened adults (280 men and 358 women) selected for a retrospective evaluation of their hearing performance with(More)
Considerable progress has been made in the treatment of hearing loss with auditory implants. However, there are still many implanted patients that experience hearing deficiencies, such as limited speech understanding or vanishing perception with continuous stimulation (i.e., abnormal loudness adaptation). The present study aims to identify specific patterns(More)
There is wide variability in the methods of follow up of patients with colorectal cancer. For the majority of patients follow up comprises regular clinical assessment and measurement of carcinoembryonic antigen (CEA) with interval colonoscopy. Regular CT examinations will additionally detect distant disease such as liver and pulmonary metastases as well as(More)
