['To investigate the subjective benefits of bilateral cochlear implantation in 33 young children after 18 months of second implant use.', 'The Wurzburg questionnaire inquiring into a range of hearing functions was filled out by the parents. Additional data concerning the daily life and well-being of the children were gathered with an open-ended questionnaire and the Categories of Auditory Performance. Results were analyzed separately for children younger and older than 6 years at the time of the second implantation.', "After 18 months of bilateral implant use 30% of the younger and 6% of the older children made the transition to an auditory-oral communication. In this period, 15% of all children switched to mainstream schools. The parents reported an evolution of their children's auditory abilities, which included a better sound and speech perception. Multiregression analysis revealed that early hearing aid fitting and the age at the second cochlear implantation significantly contributed to the variance of the Wurzburg results."] Do subjective benefits of sequential bilateral cochlear implantation in young children after 18 months of implant use?
