Digital live imaging of intraoperative electrocochleography during cochlear implantation: the first 50 patients.

Introduction: Real-time visualization of intraoperative electrocochleography (ECochG) potentials via a digital microscope during cochlear implantation can provide direct feedback during electrode insertion. The aim of this prospective, randomized study of 50 patients was to obtain long-term data with a focus on residual hearing preservation and speech understanding.

Material And Methods: Cochlear implantations were performed in 50 patients (26 female, 24 male) with residual hearing using a digital microscope.

Assessing Medial Olivocochlear Reflex Strengths via Auditory Brainstem Response: Measurement and Variability in Normal-Hearing Individuals.

Purpose: Optimal measurement settings to measure the medial olivocochlear reflex (MOCR) in humans have not yet been defined. The purpose of this study was to advance the representation of the MOCR in auditory brainstem response (ABR) as an addition to the current diagnostic portfolio.

Participants And Method: Twelve female and 14 male normal-hearing adults participated in the study.
