Outcome measures
Primary outcome
Performance on the non-looking vocal turns (NLVT) component of the Tait video analysis in the individual patient¡¯s best aided condition.
Secondary outcome
1. Localisation abilities assessed with the:
A. Left-Right discrimination test;
B. Movement Tracking Test;
C. 3-alternative localisation test.
2. Assessment of speech perception in noise with the spatial release from masking (SRM) test;
3. Assessment of auditory pathway development with ABR and cortical auditory evoked potentials.
Background summary
This study will investigate the benefit of bilateral cochlear implantation over unilateral cochlear implantation in children who are implanted with two cochlear implants either simultaneously or sequentially. The objective is to evaluate the degree of bilateral benefit gained from having a second implant. 45 Children with severe to profound sensorineural hearing loss will be included in this Randomised Controlled Trial. Half of the group shall receive one implant at the beginning of the study and a second implant after a period of two years. The other half shall receive two cochlear implants simultaneously during one operation. Objective and subjective parameters will be measured during evaluation sessions pre-operatively, 6, 12, 24, 36 and 48 months after the first cochlear implantation.
Study objective
Bilateral cochlear implantation in children has potentially an advantage over unilateral cochlear implantation in terms of communication development (both preverbal communication and language development) and sound localization. This study will compare the effects of simultaneous and sequential bilateral cochlear implantation. This not only allows to compare the effects of simultaneous and sequential bilateral cochlear implantation , but also of unilateral and bilateral cochlear implantation.
Study design
1. Preoperatively;
2. 6 months post (first) implantation;
3. 12 months post (first) implantation;
4. 24 months post (first) implantation;
5. 36 months post (first) implantation;
6. 48 months post (first) implantation.
Intervention
Simultaneous or sequential bilateral cochlear implantation.
