Bilateral cochlear implantation significantly improves quality of life and offers a favorable cost-utility for individuals with profound hearing loss. Patients experienced further gains after receiving their second cochlear implant.

Area of Science:

  • Audiology
  • Health Economics
  • Quality of Life Research

Background:

  • Profound hearing loss impacts multiple life domains.
  • Bilateral cochlear implantation (BCI) is an option for severe to profound hearing loss.
  • Understanding the quality of life (QoL) and cost-utility of BCI is crucial.

Purpose of the Study:

  • To evaluate QoL improvements following BCI.
  • To determine the cost-utility of BCI.
  • To compare QoL gains between unilateral and bilateral cochlear implant use.

Main Methods:

  • Prospective case-control study.
  • Involved 23 patients receiving bilateral cochlear implants.
  • Utilized the Mark III health utility index for assessment.

Electrically Evoked Stapedius Reflex Measurements in Cochlear Implantation and Its Application in the Postoperative Fitting Process

Published on: June 21, 2024

Main Results:

  • Mean gain in health utility of 0.48 post-BCI.
  • Discounted cost per Quality Adjusted Life Year (QALY) of $24,859.
  • Additional mean health utility gain of 0.11 when comparing unilateral to bilateral use, with improvements in hearing, speech, emotion, and cognition.

Conclusions:

  • BCI leads to improved QoL and favorable cost-utility in patients with profound hearing loss.
  • Patients experience incremental QoL benefits after receiving a second cochlear implant.
  • This study provides novel evidence on the QoL and cost-utility of BCI.
