Objective: This paper report a rare case that showed the limitation of integrity testing by telemetry in detecting the cause of cochlear implant defect.
Method: We are reporting the case of a 45-year-old female who received a cochlear implant 10 years ago, owing to a profound bilateral sensorineural hearing loss. Following the cochlear implant the patient's speech discrimination threshold improved dramatically. In March 2009, after a car accident, the patient was unable to hear. The clinical and radiological examination revealed no abnormality, nor did the telemetry test, with normal implant function and normal NRT. The proceeding medical treatment with a corticosteroid therapy and hearing rehabilitation brought no improvement. Thus we decided to revise both implantations.
Result: The cochlear reimplantation was postoperatively found to have brought a marked improvement in the hearing and speech discrimination threshold. Conclusively we chose to perform a second cochlear reimplantation on the opposite side which after surgery revealed the same postoperative result.
Conclusion: The telemetry test does not always enable one to discover the cause of the cochlear implant failure.

Comparison of behind-the-ear vs. off-the-ear speech processors in cochlear implants: A systematic review and narrative synthesis.
PLoS One

Department of Clinical Neurosciences, University of Cambridge, Cambridge, United Kingdom.
Background: Cochlear implants (CI) with off-the-ear (OTE) and behind-the-ear (BTE) speech processors differ in user experience and audiological performance, impacting speech perception, comfort, and satisfaction.
Objectives: This systematic review explores audiological outcomes (speech perception in quiet and noise) and non-audiological factors (device handling, comfort, cosmetics, overall satisfaction) of OTE and BTE speech processors in CI recipients.
Methods: We conducted a systematic review following PRISMA-S guidelines, examining Medline, Embase, Cochrane Library, Scopus, and ProQuest Dissertations and Theses.
Accuracy and variability in clinical predictions of speech recognition outcomes for cochlear implant users.

Objectives: An improvement in speech perception is a major well-documented benefit of cochlear implantation (CI), which is commonly discussed with CI candidates to set expectations. However, a large variability exists in speech perception outcomes. We evaluated the accuracy of clinical predictions of post-CI speech perception scores.

Previous studies have identified Cometin - also known as Meteroin-like - to be neuroprotective and beneficial for metabolic disorders. The aim of our study was to investigate the effects of different concentrations of recombinant human Cometin (hCometin) on SGN in regard to neuroprotection and neurite outgrowth and to evaluate its neurite guidance potential using a neurite outgrowth chamber.

Department of Otorhinolaryngology, Radboud University Medical Center, Nijmegen, The Netherlands.
Objective: To assess the impact of cochlear implantation (CI) and speech perception outcomes on the quality of life (QoL) of adult CI users and their communication partners (CP) one-year post-implantation.
Design: This research is part of a prospective multicenter study in The Netherlands, called SMILE (Societal Merit of Intervention for hearing Loss Evaluation).
Study Sample: Eighty adult CI users completed speech perception testing and the Nijmegen Cochear Implant Questionnaire (NCIQ).
