Looks like we got ahead of ourselves there...
NICE have just published their second appraisal consultation document in which they back-track on this recommendation, explicitly dropping pre-lingually deafened children from the list of those deemed suitable for bilaterals and stating:
And we were hoping, and campaigning, for a widening of the criteria to include post-lingually deafened children, who would equally benefit from improved hearing in the classroom, and adults. This is the UK's opportunity to catch up with the US and many other countries, display a little bit of common sense and act. What has caused this U-turn?
Bilateral cochlear implantation is not recommended for children and adults
(...) except in the context of research designed to generate
robust evidence about the benefits to functional hearing and health-related
quality of life of simultaneous or sequential bilateral compared with unilateral
cochlear implantation in those with severe to profound deafness who do not
receive adequate benefit from acoustic hearing aids.
If you are in any way involved, or interested, please consider responding to NICE through their website. They need telling.
