Electric-acoustic stimulation (EAS) was developed for individuals with a profound hearing loss in the high frequencies and a substantial residual low-frequency hearing (LFH). For this group of candidates, conventional hearing aids often neither provided sufficient amplification nor were they considered suitable for cochlear implantation due to the...
In normal hearing, the pitch of an acoustic tone can theoretically be encoded by either the place of stimulation in the cochlea or the corresponding rate of vibration. Thus spectral attributes and temporal fine structure of an acoustic signal are naturally correlated. Cochlear implants (CIs), neural prosthetic devices that restore hearing in the pr...
Objective:
Evaluation of a shortened delay time between surgical placement of the cochlear implant (CI) device and processor activation to less than 8 days (early CI fitting). Assessment of benefits and limits of early fitting in terms of medical, technical, audiological, and subjective outcome.
Study design:
Prospective.
Setting:
Tertiary ref...
Severe to profound hearing loss and deafness are treated with a cochlear implant (CI) fitting. Today, the indication for CI fitting in adult patients with single sided deafness (SSD) has been recognized and financed in Germany.
A magnet in the center of the CI receiver coil attaches the transmitter coil, which is worn on the outside of the head. C...
Objectives
In this study, localization accuracy and sensitivity to acoustic interaural time differences (ITDs) in subjects using cochlear implants with combined electric-acoustic stimulation (EAS) were assessed and compared with the results of a normal hearing control group.
Methods
Eight CI users with EAS (2 bilaterally implanted, 6 unilaterally...

Purpose
In recent years, the number of elderly cochlear implant (CI) candidates is continuously rising. In addition to the audiological improvement, other positive effects of CI treatment can also be observed in clinical routine. The “quality of life” as a parameter of success directly experienced by the patient is increasingly becoming the focus o...
(1) Background: The fitting of cochlear implants (CI) is an established treatment, even in cases with considerable residual hearing but insufficient speech perception. The aim of this study was to evaluate a prediction model for speech in quiet and to provide reference data and a predictive model for postoperative speech perception in noise (SPiN)...
Purpose
The aim of the presented study was to compare the audiological benefit achieved in cochlear implant (CI) patients who, in principle, could still have been treated with an active middle ear implant (AMEI) with a group of AMEI users.
Methods
Results of 20 CI patients with a pure-tone average (PTA) of 70 dB HL prior to surgery were compared w...
Background:
Although good speech perception in quiet is achievable with cochlear implants (CIs), speech perception in noise is severely impaired compared to normal hearing (NH). In the case of a bimodal CI fitting with a hearing aid (HA) in the opposite ear, the amount of residual acoustic hearing influences speech perception in noise.
Objective:...

Purpose
This study investigated whether an interaural delay, e.g. caused by the processing latency of a hearing device, can affect sensitivity to interaural level differences (ILDs) in normal hearing subjects or cochlear implant (CI) users with contralateral normal hearing (SSD-CI).
Methods
Sensitivity to ILD was measured in 10 SSD-CI subjects and...
Background
One factor which influences the speech intelligibility of cochlear implant (CI) users is the number and the extent of the functionality of spiral ganglion neurons (SGNs), referred to as “cochlear health.” To explain the interindividual variability in speech perception of CI users, a clinically applicable estimate of cochlear health could...
Background:
Hearing performance in cochlear implant (CI) users is variable. An objective measure which can allow a prediction of this performance is desirable. Spread of neural excitation (SoE) curves are an objective measure that can be obtained using the fitting software of cochlear implants and might be able to be used as a predictor. A novel m...
Purpose
The cochlear implant (CI) is a standard treatment for patients with severe to profound hearing loss. In recent years, early device activation of the sound processor after 2–3 days following surgery has been established. The aim of this study is to evaluate the residual hearing of CI patients with substantial preoperative low-frequency heari...

Hearing loss in old age, which often goes untreated, has far-reaching consequences. Furthermore, reduction of cognitive abilities and dementia can also occur, which also affects quality of life. The aim of this study was to investigate the hearing performance of seniors without hearing complaints with respect to speech perception in noise and the a...
Nowadays, several options are available to treat patients with
conductive or mixed hearing loss. Whenever surgical intervention is not possible or contra-indicated, and amplification by a
conventional hearing device (e.g., behind-the-ear device) is
not feasible, then implantable hearing devices are an indispensable next option. Implantable bone-con...
Purpose
Even in older patients, hearing rehabilitation with a cochlear implant has become an established method for deafened or severely hearing-impaired patients. In addition to the hearing improvement, numerous other effects of CI treatment can be observed in clinical routine. In the literature, there is multiple evidence for a rapid and signific...

Introduction:
Transimpedance measurements from cochlear implant electrodes have the potential to identify anomalous electrode array placement, such as tip fold-over (TFO) or fold-back, basal electrode kinking, or buckling. Analysing transimpedance may thus replace intraoperative or post-operative radiological imaging to detect any potential mispla...
Purpose
The treatment with a cochlear implant (CI) is the gold standard in therapy of patients with profound hearing loss or deafness. Successful hearing rehabilitation with a CI is a complex, multi-stage process. In medicine, “Clinical Practice Guidelines” (CPG) are widely accepted for the standardization of such processes. These are supplemented...

Background:
The cochlear implant (CI) is a standard procedure for the treatment of patients with severe to profound hearing loss. In the past, a standard healing period of 3-6 weeks occurred after CI surgery before the sound processor was initially activated. Advancements of surgical techniques and instruments allow an earlier initial activation o...
Die Cochlea Implantat Operation setzt die Verwendung eines technisch fehlerfreien Implantats voraus. Bei der CI-Operation besteht daher die Möglichkeit, eine Funktionsprüfung des Geräts vor der Implantation durchzuführen. Neben einer visuellen Prüfung kann auch eine "Leermessung" dazu dienen, mögliche technische Defekte, wie Kurzschlüsse oder offen...
In everyday life listening situations, communication is characterized by a variety of challenging acoustic scenes. Usually, background noise sources are present and, additionally, direct sound in rooms is reflected from walls and surfaces. These reflections affect speech perception. However, audiological assessments are usually performed in rooms w...
