Introduction:
An increasing number of long-term users of bone conduction implants (BCI) have been observed to no longer obtain sufficient benefit from their device due to deteriorations in hearing thresholds. At the multidisciplinary auditory implant centre at the University College London Hospitals NHS Trust, these patients are assessed and considered for cochlear implantation (CI). This case series describes the history and outcomes of patients who became bimodal implant users, utilising electrical and vibratory auditory stimulation with a BCI and CI. This unique patient group has seldom been described in the literature.
Methods:
Case series from a retrospective chart review of patients who utilise the combination of electrical and vibratory auditory stimulation with the use of a bone conduction implant and cochlear implant, up to November 2023.
Results:
Six bimodal patients were identified from the patient cohort. Their case history and outcome are described.
Conclusion:
The synergy of electrical and vibratory auditory stimulation observed in this case series provided subjective functional benefits and measurable speech perception benefits for some patients, while others experienced minimal or no measurable benefit and ceased usage.
