Objectives: To compare hearing outcomes in patients with far advanced otosclerosis (FAO) undergoing cochlear implantation to an age-matched group of controls, to describe the effects of cochlear ossification on hearing, and to review the adverse effects of implantation in patients with FAO.
Hypothesis: Hearing performance in patients with FAO after cochlear implantation is comparable to similarly treated postlingually deafened adults without FAO. Ossification or retrofenestral otosclerosis does not predict poor hearing outcomes. Modiolar-hugging technology reduces postoperative facial nerve stimulation.
Study Design: Retrospective chart review.
Setting: Academic neurotologic tertiary referral center.
Patients: Thirty patients with FAO, who metaudiological criteria for cochlear implantation, were compared to 30 age-matched controls, postlingually deafened by non-otosclerotic causes.
Main Outcome Measures: Audiometric pre- and postoperative speech reception threshold, word, and sentence scores were analyzed. The presence of retrofenestral findings on computed tomography or intraoperative cochlear ossification were noted.
Results: In the FAO group, radiographic abnormalities were noted in 26.4% of patients. Intraoperative ossification requiring drillout was seen in 29.4% of patients. None developed postoperative facial nerve stimulation. There was no difference between the FAO and control groups in the mean short-term and long-term postoperative speech reception threshold, word, and sentence scores (P = .77). The presence of radiographic abnormalities did not predict hearing outcome. Intraoperative cochlear ossification was not associated with worse short-term word and sentence scores (P = .58 and 0.79, respectively), and for the long-term hearing outcome (P = .24).
Conclusions: In patients with FAO, effective and safe hearing rehabilitation can be accomplished with cochlear implantation.

Purpose: Cochlear implants (CI) are the most successful bioprosthesis in medicine probably due to the tonotopic anatomy of the auditory pathway and of course the brain plasticity. Correct placement of the CI arrays, respecting the inner ear anatomy are therefore important. The ideal trajectory to insert a cochlear implant array is defined by an entrance through the round window membrane and continues as long as possible parallel to the basal turn of the cochlea.

Purpose: Evaluate the feasibility and safety of a robotic electrode insertion in pediatric cochlear implantation and compare the results with manually inserted electrodes in the same subject.
Methods: Retrospective case series review of four children who underwent bilateral cochlear implantation with the same array: on one side, the array was inserted using the robot, while on the other side the array was inserted manually. Behavioural and electrophysiological measures were compared.

Importance: There is a lack of high level of evidence studies comparing the effect of different treatment options for single-sided deafness (SSD).
Objective: To determine the effect of a cochlear implant (CI), bone conduction device (BCD), contralateral routing of signals hearing aid (CROS), and no treatment on speech perception in noise outcomes in patients with SSD.
Design, Setting, And Participants: In this single-center randomized clinical trial, adult patients with SSD were randomized into 3 groups: CI; a trial period with first a BCD on a headband and then a CROS; or a trial period with first a CROS and then a BCD on a headband.

When listening to speech under adverse conditions, listeners compensate using neurocognitive resources. A clinically relevant form of adverse listening is listening through a cochlear implant (CI), which provides a spectrally degraded signal. CI listening is often simulated through noise-vocoding.

Background: Pediatric cochlear implant (CI) recipients with cochlear malformations face challenges due to variable speech recognition outcomes.
Aims/objectives: This study assesses the predictive value of intraoperative electrically evoked compound action potential (eCAP) thresholds, residual hearing, age at implantation, Intelligent Quotient (IQ), and malformation type for speech recognition outcomes.
Material And Methods: A prospective cohort of 52 children (aged 1-4 years) with cochlear malformations who underwent CI between 2016 and 2024 was analyzed.
