title: Intraoperative electrophysiological and objective tests after cochlear re-implantation in a young child.
abstract: The electrically evoked auditory brainstem response (EABR) and stapedius reflex threshold (ESRT) are routinely recorded during implant surgery with the Nucleus 22 channel cochlear implant in the Nottingham Paediatric Cochlear Implant Programme and are extremely valuable in the management of young implanted children. These intraoperative tests were carried out in a young child on the occasion of the first implantation and then after re-implantation 17 months later following malfunction of the first device. The surgical experiences of the first implantation and the re-implantation were both straightforward. Recordings of the intraoperative EABR and ESRT were typical of the expected pattern of responses on both occasions and there was only a small reduction in threshold sensitivity after re-implantation. These investigations provide valuable objective information to support and assist with the management of re-implantation in a young child.
