Unilateral cochlear implantation has become a widely accepted surgical intervention for both deaf children and adults. It is a reliable and effective method to rehabilitate profound deafness. Recently the benefits of the use of a contralateral hearing aid (bimodal stimulation) with a cochlear implant became clear. Bilateral cochlear implantation benefits bilateral input into the auditory system for adults and children. To provide the binaural advantages experienced by normal hearing subjects bilateral cochlear implantation or bimodal stimulation is probably indicated. Whether to choose between both possibilities depends on many factors. Cortical auditory evoked potential (CAEP) measurements can be an important tool to decide bilateral implantation in young children. Enough residual hearing in the non-implanted ear might benefit from bimodal stimulation. New protocols are needed for the audiological management for recipients of cochlear implants.

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.

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.

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).

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.
