Electrically Evoked Stapedius Reflex Measurements in Cochlear Implantation and Its Application in the Postoperative Fitting Process07:00

Electrically Evoked Stapedius Reflex Measurements in Cochlear Implantation and Its Application in the Postoperative Fitting Process

1.5K
The present protocol describes the measurement of the electrically evoked stapedius reflex (eSR) via cochlear implant (CI). Two applications are discussed: intraoperative detection of eSR for verification of the coupling between the cochlear implant and the auditory nerve and postoperative measurement of eSR thresholds (eSRT) for CI...

Study Design for Navigated Repetitive Transcranial Magnetic Stimulation for Speech Cortical Mapping

1.9K
Navigated repetitive transcranial magnetic stimulation is a highly efficient non-invasive tool for mapping speech-related cortical areas. It helps in designing brain surgery and speeds up the direct cortical stimulation conducted during the surgery. This report describes how to perform speech cortical mapping reliably for preoperative evaluation and research.

Performing Repeated Intraoperative Impedance Telemetry Measurements during Cochlear Implantation

1.7K
Here we present a protocol to conduct repeated impedance telemetry measurements during cochlear implantation (CI). They may allow conclusions on the electrode's and implant's function. Repeated impedance measurements enable objective feedback on whether the electrode is positioned inside the perilymph or outside the inner...

Area of Science:

  • Audiology
  • Biomedical Engineering
  • Rehabilitation Medicine

Background:

  • Cochlear implants (CI) are crucial for hearing rehabilitation in severe hearing loss.
  • Effective speech discrimination is key for CI patients' communication and social integration.
  • Next-generation speech processors (SP) aim to enhance auditory perception.

Purpose of the Study:

  • To evaluate the impact of newer speech processors (SP) on speech discrimination in cochlear implant (CI) users.
  • To determine if technological advancements in SP improve auditory outcomes.
  • To assess the generalizability of SP benefits across different patient demographics.

Main Methods:

  • Retrospective analysis of speech discrimination data from 420 CI patients.
  • Utilized Freiburg number and monosyllable tests, and Oldenburg sentence test.
  • Tested in quiet and noise conditions at a consistent 70 dB presentation volume.

Main Results:

  • Newer SP demonstrated statistically significant improvements in speech discrimination across all tested audiometric measures.
  • The observed benefits were consistent for the majority of the patient cohort.
  • Speech discrimination improvements were not influenced by patient age.

Conclusions:

  • Upgrading to newer speech processors (SP) leads to enhanced speech discrimination for CI users.
  • The benefits of SP upgrades are evident across various testing scenarios.
  • Earlier upgrades and coverage for new SP are recommended to maximize patient benefit.
