Revision Cochlear Implantation With Device Manufacturer Conversion: Surgical Outcomes and Speech Perception Performance.

Objective: Describe the clinical profile of revision cochlear implantation (RCI) cases involving device manufacturer conversion (RCI), compare them to cases without manufacturer conversion (RCI), and classify the reasons for manufacturer conversion (MC).

Study Design: Retrospective case review.

Setting: Tertiary academic center.

Rates, Indications, and Speech Perception Outcomes of Revision Cochlear Implantations.

Revision cochlear implant (RCI) is a growing burden on cochlear implant programs. While reports on RCI rate are frequent, outcome measures are limited. The objectives of the current study were to: (1) evaluate RCI rate, (2) classify indications, (3) delineate the pre-RCI clinical course, and (4) measure surgical and speech perception outcomes, in a large cohort of patients implanted in a tertiary referral center between 1989-2018.

Current demographic and auditory profiles of adult cochlear implant candidates and factors affecting uptake.

Objectives: Despite growth of CI and widening of implantation criteria, penetration rates remain low and the clinical profile of adult CI candidates has not substantially changed. This study evaluated the demographic and auditory profiles of current adult CI candidates and identified factors affecting CI uptake.

Design: Preoperative data from patients who underwent CI candidacy evaluation between 2016-2018 were retrospectively reviewed.

Hearing with Two Ears: Evidence for Cortical Binaural Interaction during Auditory Processing.

Background: Integration of information presented to the two ears has been shown to manifest in binaural interaction components (BICs) that occur along the ascending auditory pathways. In humans, BICs have been studied predominantly at the brainstem and thalamocortical levels; however, understanding of higher cortically driven mechanisms of binaural hearing is limited.

Purpose: To explore whether BICs are evident in auditory event-related potentials (AERPs) during the advanced perceptual and postperceptual stages of cortical processing.

Pain in cochlear implant recipients: an uncommon, yet serious, consequence of cochlear implantation.

Objectives/hypothesis: We describe pain around the receiver/stimulator [RS] presenting months to years after implantation.

Study Design: A retrospective chart review.

Methods: We performed a retrospective review of all cochlear implant recipients complaining of pain around their RS through the years 2009 through 2013, with a follow-up of at least 6 months.

Neural correlates of auditory-cognitive processing in older adult cochlear implant recipients.

With the growing number of older adults receiving cochlear implants (CI), there is general agreement that substantial benefits can be gained. Nonetheless, variability in speech perception performance is high, and the relative contribution and interactions among peripheral, central-auditory, and cognitive factors are not fully understood. The goal of the present study was to compare auditory-cognitive processing in older-adult CI recipients with that of older normal-hearing (NH) listeners by means of behavioral and electrophysiologic manifestations of a high-load cognitive task.

Auditory conflict processing: behavioral and electrophysiologic manifestations of the stroop effect.

Background: One of the most extensively studied phenomena in cognitive neuroscience is the Stroop effect. In an enormous corpus of literature, the Stroop task has been used to study conflict processing in the visual modality; however, scarce data exist in the auditory modality.

Purpose: The main goal of the present study was to investigate auditory conflict processing by means of behavioral and electrophysiologic measures elicited during standard and reversed Stroop tasks.
