A recent trend has been the implantation of bilateral cochlear implants (CIs) for children with severe to profound hearing loss. A review of available research on bilateral CIs was conducted to determine the support for this trend. A replicable review was undertaken to evaluate published research studies that examined the effectiveness of bilateral paediatric cochlear implantation. Databases, reference lists, and journals were searched for relevant documents using a pre-determined search protocol. Twenty-nine articles met the review's inclusion criteria and were retrieved and reviewed. This review adds to the previously published reviews on the topic by identifying additional paediatric studies. Sound localization and speech recognition in noise appear to be improved with bilateral compared to unilateral cochlear implants. Similarly, evoked potential measures suggest improved morphology when the second CI is implanted early. Well-designed and controlled studies that explore a variety of outcomes including cost-effectiveness, quality of life, speech, language, and psycho-educational measures should be further explored in order to provide additional support for parents and clinicians confronted with the bilateral cochlear implant decision.

Introduction: Neurotrophic factors are widely known for their protective effect on spiral ganglion neurons (SGN) and the protection of these neurons is of great importance to optimize Cochlear Implants, which directly stimulate SGN in deaf patients. 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.

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).
Ultra-high-resolution CT of the temporal bone before cochlear implantation for pre-operative prediction of chorda tympani nerve management and round window access.

Background And Purpose: To evaluate various anatomical parameters and their relationship to chorda tympani nerve (CTN) injury and round window (RW) access during cochlear implantation.
Materials And Methods: Ultra-high-resolution CT images of 66 patients were retrospectively reviewed and compared with operative reports. The facial recess and the round window were analyzed, mainly using the chorda-facial angle (CFA), the width of the facial recess, the CTN-tympanic annulus distance, the RW-mastoid portion of the facial nerve angle, and the type of RW.
Factors Associated With Social-Pragmatic Understanding in Deaf and Hard of Hearing and Typically Hearing 6-Year-Old Children.

Purpose: Children develop social-pragmatic understanding with the help of sensory, cognitive, and linguistic functions by interacting with other people. This study aimed to explore (a) associations between auditory, demographic, cognitive, and linguistic factors and social-pragmatic understanding in children who use bilateral hearing aids (BiHAs) or bilateral cochlear implants (BiCIs) and in typically hearing (TH) children and (b) the effect of the group (BiHA, BiCI, TH) on social-pragmatic understanding when the effects of demographic, cognitive, and linguistic factors are controlled for.
Method: The Pragma test was used to assess social-pragmatic understanding in 119 six-year-old children: 25 children who use BiHAs, 29 who use BiCIs, and 65 TH children.
Effects of Microstructured and Anti-Inflammatory-Coated Cochlear Implant Electrodes on Fibrous Tissue Growth and Neuronal Survival.

Cochlear implants are well established devices for treating severe hearing loss. However, due to the trauma caused by the insertion of the electrode and the subsequent formation of connective tissue, their clinical effectiveness varies. The aim of the current study was to achieve a long-term reduction in connective tissue growth and impedance by combining surface patterns on the electrode array with a poly-L-lactide coating containing 20% diclofenac.
