Impact of Vestibular Schwannoma Management on Cochlear Implant Programming and Outcomes.

Objectives: To compare electrical stimulation and speech perception in vestibular schwannoma (VS) patients across treatment modalities and standard cochlear implant (CI) patients.

Study Design: Retrospective review.

Setting: Tertiary academic center.

Electrode Impedance Subcomponent Analysis in Cochlear Implant Patients with Rising or Fluctuating Electrode Impedances.

Background/objectives: Electrode impedance is crucial for optimizing cochlear implant (CI) stimulation and hearing outcomes. While typically stable, some patients experience unexplained impedance fluctuations. This study used electrode impedance subcomponent analysis to identify the subcomponents contributing to these impedance fluctuations.

Detection of Extracochlear Electrodes Using Electrical Field Imaging (EFI).

Objective: To analyze the use of electrical field imaging (EFI) in the detection of extracochlear electrodes in cochlear implants (CI).

Study Design: Retrospective cohort study.

Setting: Tertiary academic medical center.

How Does Deep Neural Network-Based Noise Reduction in Hearing Aids Impact Cochlear Implant Candidacy?

Background/objectives: Adult hearing-impaired patients qualifying for cochlear implants typically exhibit less than 60% sentence recognition under the best hearing aid conditions, either in quiet or noisy environments, with speech and noise presented through a single speaker. This study examines the influence of deep neural network-based (DNN-based) noise reduction on cochlear implant evaluation.

Methods: Speech perception was assessed using AzBio sentences in both quiet and noisy conditions (multi-talker babble) at 5 and 10 dB signal-to-noise ratios (SNRs) through one loudspeaker.

Early Hearing Outcomes and Audiological Experiences With a Novel Fully Implanted Cochlear Implant.

Objective: To review audiological experiences and early hearing outcomes from the early feasibility study of a fully implanted cochlear implant.

Study Design: Prospective cohort.

Setting: Tertiary academic medical center.

AI model for predicting adult cochlear implant candidacy using routine behavioral audiometry.

Objective: To describe an AI model to facilitate adult cochlear implant candidacy prediction based on basic demographical data and standard behavioral audiometry.

Methods: A machine-learning approach using retrospective demographic and audiometric data to predict candidacy CNC word scores and AzBio sentence in quiet scores was performed at a tertiary academic center. Data for the model were derived from adults completing cochlear implant candidacy testing between January 2011 and March 2023.

Pathophysiology of Facial Nerve Stimulation and Its Implications for Electrical Stimulation in Cochlear Implants.

Objectives: A small number of cochlear implant (CI) users experience facial nerve stimulation (FNS), which can manifest as facial twitching. In some patients, this can be resolved by adjusting the electrical stimulation parameters. However, for others, facial stimulation can significantly impair CI outcomes or even prevent its use.

Implementation Strategy for Highly-Coordinated Cochlear Implant Care With Remote Programming: The Complete Cochlear Implant Care Model.

Objective: To introduce and discuss implementation strategy for the Complete Cochlear Implant Care (CCIC) model, a highly-coordinated cochlear implant (CI) care delivery model requiring a single on-site visit for preoperative workup, surgery, and postoperative programming.

Study Design: Prospective, nonrandomized, two-arm clinical trial.

Setting: Tertiary referral CI center.

Language and Audiological Outcomes Among Infants Implanted Before 9 and 12 Months of Age Versus Older Children: A Continuum of Benefit Associated With Cochlear Implantation at Successively Younger Ages.

Objective: To compare language and audiological outcomes among infants (<9 and <12 mo) and older children receiving cochlear implantation (CI).

Study Design: Retrospective chart review.

Setting: Tertiary academic referral center.

Application of Kaizen Principles to a Large Cochlear Implant Practice: A Continuous Quality Improvement Initiative at Mayo Clinic.

Objective: To remove barriers and improve access for patients seeking cochlear implantation.

Study Design: Prospective quality improvement study at a large tertiary academic care center.

Methods: A Kaizen quality improvement model was applied over the course of a year.

Cochlear implantation for single-sided deafness in children and adolescents.

Objective: To evaluate outcomes in pediatric and adolescent patients with single-sided deafness (SSD) undergoing cochlear implantation.

Methods: A retrospective cohort design at two tertiary level academic cochlear implant centers. The subjects included nine children ages 1.

Hearing Preservation in Pediatric Cochlear Implantation.

Objective: Currently, there is a paucity of literature evaluating hearing preservation outcomes in children following cochlear implantation. The objective of the current study is to report pediatric hearing preservation results following cochlear implantation with conventional full-length electrodes.

Study Design: Retrospective review (2000-2016).

Early outcomes after cochlear implantation for adults and children with unilateral hearing loss.

Objectives/hypothesis: This study was designed to examine speech recognition and self-perceived health-related quality of life (HRQoL) received from cochlear implantation among a cohort of adults and children with a short duration of unilateral hearing loss greater than 6 months, but less than 2 years.

Study Design: Single-subject repeated measures prospective study.

Methods: This study assessed changes in speech recognition and self-perceived quality of life by prospectively analyzing data at the preoperative evaluation and at the 3-month and 6-month postactivation intervals.

Evidence for the expansion of pediatric cochlear implant candidacy.

Objective: To test the hypothesis that children who are non-traditional cochlear implant candidates, but are not making progress with appropriately fitted hearing aids and intervention, will demonstrate significant benefit from cochlear implantation as defined by improvement in (1) speech perception, (2) auditory skills development, and/or (3) progress on standardized measures of receptive and expressive language.

Study Design: Retrospective case series.

Setting: Two tertiary academic cochlear implant centers.

Development and validation of the pediatric AzBio sentence lists.

Objectives: The goal of this study was to create and validate a new set of sentence lists that could be used to evaluate the speech-perception abilities of listeners with hearing loss in cases where adult materials are inappropriate due to difficulty level or content. The authors aimed to generate a large number of sentence lists with an equivalent level of difficulty for the evaluation of performance over time and across conditions.

Design: The original Pediatric AzBio sentence corpus included 450 sentences recorded from one female talker.

Cochlear implantation in children with auditory neuropathy spectrum disorder: long-term outcomes.

Background: Best practices concerning the audiological management of the child diagnosed with auditory neuropathy spectrum disorder (ANSD) have not been definitively defined nor fully understood. One reason is that previous studies have demonstrated conflicting findings regarding the outcomes of cochlear implantation for children with ANSD. Thus, the question remains whether children with ANSD are able to achieve similar outcomes following cochlear implantation as those children with sensorineural hearing loss (SNHL).
