Area of Science:

  • Otolaryngology
  • Biomedical Engineering
  • Auditory Implants

Background:

  • Osseous atresia and chronic otitis media present challenges for hearing restoration.
  • Conventional treatments and hearing aids have limitations in achieving optimal functional gain.
  • Active middle ear implants offer a potential alternative for complex hearing loss cases.

Purpose of the Study:

  • To evaluate the clinical utility of the Vibrant-Soundbridge active middle ear implant.
  • To assess hearing recovery in patients with severe mixed hearing loss due to atresia or chronic otitis media.

Main Methods:

  • A longitudinal study involving eight patients with severe mixed hearing loss.
  • Vibrant-Soundbridge implantation with Floating Mass Transducer (FMT) placement on the round window, stapes, or oval window.

Enhanced Cochlear Coverage and Hearing Preservation in High-Frequency Hearing Loss via Electric Acoustic Stimulation with Longer Electrode

Published on: October 11, 2024

  • Four patients had chronic otitis media, and four had unilateral atresia.

    • Main Results:

    • Significant functional gain was achieved across various frequencies, with gains of 35 dB (500 Hz), 40 dB (1000 Hz), 48.7 dB (2000 Hz), and 50 dB (4000 Hz).

    Conclusions:

    • The Vibrant-Soundbridge is a highly effective option for hearing restoration in severe to profound mixed hearing loss.
    • It demonstrates excellent functional gain in cases where conventional hearing aids are less effective.
    • This active middle ear implant represents a valuable therapeutic choice for difficult-to-treat auditory conditions.
