Unilateral Cochlear Implants for Severe, Profound, or Moderate Sloping to Profound Bilateral Sensorineural Hearing...

Area of Science:

• Otolaryngology
• Audiology
• Neurosurgery

Background:

• Cochlear implantation is an option for severe to profound sensorineural hearing loss (SNHL) unresponsive to hearing aids.
• However, cochlear implantation in adults is not yet a routine procedure.

Purpose of the Study:

• To establish consensus statements for the use of unilateral cochlear implants in adults with SNHL.
• To provide evidence-based guidelines for clinical practice.

Main Methods:

• A modified Delphi consensus process involving 30 international specialists.
• Systematic literature review across MEDLINE, Embase, and Cochrane Library.
• Two rounds of email questionnaires and a face-to-face meeting for refinement.

Main Results:

• 20 evidence-based consensus statements were developed from 74 selected articles.
• Statements cover awareness, clinical pathways, surgical guidelines, effectiveness, outcomes, hearing loss associations, and cost.
• The statements align with clinical experience and address key areas of cochlear implantation.

Conclusions:

• These statements are a foundational step towards international guidelines for adult cochlear implantation.
• Further research is recommended for pediatric cases, bilateral implants, and single-sided deafness.
• Optimizing hearing and quality of life for patients is the ultimate goal.
