NCT03382769

Brief Summary

This is a prospective, 1:1 randomized controlled trial of immediate versus delayed cochlear implantation (CI) on hearing handicap, communicative function, loneliness, mental wellbeing, and cognitive functioning. Participants are randomized 1:1 to an immediate cochlear implant intervention group versus a hearing aid control intervention.

Outcome Measures

Primary Outcomes (1)

  • Hearing Handicap

    The SSQ-12 is comprised of 12 items using the response format on a scale from 0 to 10, were 0 equals no ability and 10 equals perfect ability. These are divided into three sub-scales and the questions 1-5 are from the speech sub-scale, 6-8 from the spatial, and 9-12 from the qualities sub-scale. The three sub-scales are the average of the questions within. A 'not applicable' option is given for each item. Assessment of the impact of cochlear implantation versus continued hearing aid is then calculated and the theoretical score could vary between -10 to + 10. The higher the score the better benefit and positive score indicates improved hearing, a negative value an impaired hearing.

    6 months after enrollment

Study Arms (2)

Group A (Immediate Cochlear Implantation)

EXPERIMENTAL

Group A will consist of 30 individuals who are candidates for cochlear implantation. They will be unilaterally implanted immediately after initial study testing has been completed and then be followed for 12 months after device activation.

Device: Cochlear implantation

Group B (Delayed Cochlear Implantation)

ACTIVE COMPARATOR

Group B will consist of 30 individuals who are candidates for cochlear implantation. They will continue to wear hearing aids after enrolling in the study and then be unilaterally implanted 6 months after enrollment and followed for 6 more months after device activation.

Device: Cochlear implantation

Interventions

Unilateral implantation with a commercially approved Nucleus cochlear implant

Group A (Immediate Cochlear Implantation)Group B (Delayed Cochlear Implantation)

  • Previous cochlear implantation in either ear
  • Hearing loss of neural or central origin
  • Permanent conductive hearing impairment (e.g. otosclerosis)
  • Medical, audiological, or psychological conductions that might contraindicate participation in the clinical investigation
  • Self reported disability in 2 or more activities of daily living
  • Vision impairment worse than 20/40 on a near vision card
