[New method of partial deafness treatment].

Area of Science:

• Audiology
• Otolaryngology
• Biomedical Engineering

Background:

• Current treatments for hearing loss include hearing aids (mild to severe) and cochlear implants (profound deafness).
• A significant patient group experiences partial deafness, with normal low-frequency hearing and high-frequency deafness, inadequately addressed by existing methods.
• Cochlear implantation was previously contraindicated for partial deafness due to concerns about damaging residual cochlear function.

Observation:

• A novel treatment utilizing a partially-inserted cochlear implant was applied to a young woman with partial deafness.
• This method aimed to restore high-frequency hearing via electrical stimulation while preserving low-frequency acoustic hearing.

Findings:

• The treatment successfully restored high-frequency hearing in the implanted ear.
• Combining unilateral electric stimulation with bilateral acoustic stimulation led to significant improvements in speech discrimination.
• Enhanced communication skills were observed in the patient following the intervention.

Implications:

• Partial cochlear implantation offers a viable therapeutic option for individuals with partial deafness.
• This approach expands treatment possibilities for hearing loss beyond current prosthetic limitations.
• Further research may validate this technique for a broader patient population with similar hearing profiles.
