Each year we collect data from UK cochlear implant centre coordinators about the number of people using and receiving cochlear implants in the United Kingdom; from 2021-22 we also ask about referrals for CI assessment. Please note that some centres may have included reimplantation and revision surgery numbers in their new CI activity prior to 2021-22; we asked for reimplantation and revision surgery to be excluded from 2021-22 onwards. (Some centres may class under 19 as ‘children’; others may use under 18). An error was found in data from 2021-2022, so a revised version is below:
