Introduction: The benefits of electro-acoustic stimulation (EAS) are well known in patients who have residual
low frequency hearing. The Nucleus CP900 series sound processor has the capability to add an acoustic
component and this can easily be trialled and subsequently removed if there is no clinical benefit. This was not
practical in a paediatric population with previous EAS systems produced by Cochlear.
Methods: Five paediatric unilateral Nucleus CI users were identified within our paediatric population as possible
candidates for a Hybrid fitting. If these children are deemed suitable, they will trial the CP910 sound processor
with and without the acoustic component. Their performance and acceptance of the processors will also be
compared.
Measures will include the Automated Toy Test in quiet and in noise and the Brief Assessment of Parental
Perception, which is a measure created by the UK Cochlear Implant Psychology Group, currently undergoing
validation. This is a quality of life measure appropriate for routine clinical practice in the paediatric population.
Results and conclusions: Two of the five unilateral users were candidates for a Hybrid fitting. Results and
conclusions of the two hybrid fittings and their performance with and without the acoustic component will be
presented.
Learning outcome: Based on previous research we predict that the children will accept and prefer the additional
acoustic input made possible through the Hybrid mode on the CP900 processor.
