    Summary

    All study participants experienced profound sensorineural hearing loss, with most cases being bilateral. Implant surgery did not negatively impact middle ear function, as confirmed by tympanometric testing.

    Area of Science:

    • Audiology
    • Otolaryngology
    • Neurosurgery

    Background:

    • Sensorineural hearing loss (SNHL) is a significant auditory impairment.
    • Cochlear implantation is a common treatment for severe to profound SNHL.
    • Assessing audiological outcomes and middle ear status post-implantation is crucial.

    Purpose of the Study:

    • To evaluate the audiological status of subjects with profound hearing loss.
    • To assess the impact of implant surgery on middle ear function.

    Main Methods:

    • Audiological testing was performed on all subjects.
    • Tympanometric testing was used to evaluate middle ear function.

    Main Results:

    • All subjects presented with profound sensorineural hearing losses.

    Related Experiment Videos

  • Hearing loss was bilateral in 12 out of 13 subjects.
  • Tympanometry showed no disruption of middle ear function following implant surgery.

    • Conclusions:

    • Subjects exhibited severe bilateral hearing impairment.
    • Implant surgery appears safe concerning middle ear function.
