Cochlear Implant Candidacy Criteria

 

Adults

  • Individuals 18 years of age or older

  • Moderate to profound sensorineural hearing loss in both ears

  • Limited benefit from amplification defined by preoperative test scores of ≤ 50% sentence recognition in the ear to be implanted and ≤60% in the opposite ear or binaurally1 

Children (2-17 Years)*

  • Severe to profound sensorineural hearing loss in both ears

  • Limited benefit from binaural amplification

  • Multisyllabic Lexical Neighborhood Test (MLNT)* or Lexical Neighborhood Test (LNT) scores ≤ 30%

Children (9-24 Months)*^

  • Profound sensorineural hearing loss in both ears

  • Limited benefit from binaural amplification

Important Considerations:

  • Remember that many individuals with residual low frequency hearing are CI candidates and can benefit from CI.

  • When appropriate, discuss use of acoustic hearing: Does your patient have a passion for music? Work in noisy or reverberant environments? What are lifestyle demands?

  • Determine motivation to experiment with hearing aids, in both the implanted and/or contralateral ears.

  • Discuss the opportunity to use acoustic hearing to manage expectations and rehabilitation options, when appropriate.

*In Canada, the cochlear implant system is intended for use in children 12 to 24 months of age who have profound sensorineural hearing loss in both ears and demonstrate limited benefit from appropriate hearing aids. Children two years of age or older may demonstrate severe to profound hearing loss in both ears.

^ To reduce the risk of anesthetic-related adverse events, a pediatric anesthesiologist should be present during surgery for infants implanted under 12 months of age.
