Biological Response Dynamics to Cochlear Implantation: Modeling and Modulating the Electrode-Tissue Interface.

Objective: The present study primarily aims to study and model the impedance dynamics following cochlear implant (CI) surgery in humans. Secondarily, to observe how the modulation of a single-dose topic dexamethasone alters this response.

Design: CI impedance and impedance subcomponents were measured in a day-by-day basis between CI surgery and its activation ( 1 month).

Toward Self-Measures in Cochlear Implants: Daily and "Homemade" Impedance Assessment.

Cochlear implant (CI) impedance reflects the status of the electro neural interface, potentially acting as a biomarker for inner ear injury. Most impedance shifts are diagnosed retrospectively because they are only measured in clinical appointments, with unknown behavior between visits. Here we study the application and discuss the benefits of daily and remote impedance measures with software specifically designed for this purpose.

Measuring the Electrical Status of the Bionic Ear. Re-thinking the Impedance in Cochlear Implants.

As in any biophysical electrode-tissue environment, impedance measurement shows a complex relationship which reflects the electrical characteristics of the medium. In cochlear implants (CIs), which is mostly a stimulation-oriented device, the actual clinical approach only considers one arbitrary time-measure of the impedance. However, to determine the main electrical properties of the cochlear medium, the overall impedance and its subcomponents (i.

International registry of otolaryngologist-head and neck surgeons with COVID-19.

Background: It has become clear that healthcare workers are at high risk, and otolaryngology has been theorized to be among the highest risk specialties for coronavirus disease 2019 (COVID-19). The purpose of this study was to detail the international impact of COVID-19 among otolaryngologists, and to identify instructional cases.

Methods: Country representatives of the Young Otolaryngologists-International Federation of Otolaryngologic Societies (YO-IFOS) surveyed otolaryngologists through various channels.

In Vivo Real-time Remote Cochlear Implant Capacitive Impedance Measurements: A Glimpse Into the Implanted Inner Ear.

Objectives: To propose a remote, real-time, safe, and easy systematic method to determine electrode electric impedance components: access resistance, polarization capacitance, and polarization resistance.

Patients: Patients who received a cochlear implant and had normal cochlear anatomy and complete array insertion were recruited. A total of four adult patients were included and separated in two groups according to implantation time.

Real-Time Intracochlear Electrocochleography Obtained Directly Through a Cochlear Implant.

Hypothesis: Utilizing the cochlear implant to record electrophysiologic responses during device placement is a feasible and efficacious technique for monitoring near real-time cochlear physiology during and following electrode insertion.

Background: Minimizing intracochlear trauma during cochlear implantation has emerged as a highly researched area to help improve patient performance. Currently, conventional cochlear implant technology allows for the recording of electrically evoked compound action potentials (eCAPs).
