The aim of this project is to investigate the long-term speech perception and production of a well-defined cohort of young implanted children deafened by meningitis before the acquisition of spoken language. The study is designed to address the weaknesses of previous studies by being longitudinal, homogenous and consecutive; there will be no exclusions (such as poor performers). Outcomes will be compared to the corresponding outcomes from congenitally deaf children and the variability of the results of the post-meningitic children will be explored in order to assess the relative contribution of possible factors (age, mode of communication, type of meningitis, etc.). Power analysis determined that at least 40 post-meningitic deaf children are needed for the project. Parental views and concerns will also be explored in order to evaluate cochlear implantation in children deafened by meningitis from the parental perspective. The results of the study may have major implications on service provision for these children. They will advance current knowledge, enable parents and professionals to have realistic expectations, improve candidate selection and post-operative rehabilitation, and suggest measures that can further improve the speech skills of implanted children deafened by meningitis. The study could thus improve the cost-effectiveness of cochlear implantation in these children and influence the NHS funding of the intervention.

Results from this study have been published in a scientific journal as follows:
