Objectives: To review functional outcomes in children undergoing cochlear implantation for single-sided deafness after meningitis. Material and Methods: A 7 year old boy developed unilateral profound sensorineural hearing loss after Group A Streptococcus meningitis and septicemia secondary to sinusitis. Hearing in the contralateral ear was normal. Reduced signal intensity in the affected cochlea was noted on T2 weighted MRI images. Cochlear implantation was performed within 5 weeks of the onset of meningitis. Significant fibrosis of the basal turn adjacent to the round window was encountered. There was no ossification of the basal turn of the cochlea. As a depth gauge could be fully inserted into the cochlea, a MedEl Synchrony implant with a Flex28 electrode was placed. Excellent waveforms were obtained intraoperatively on Auditory Nerve Response Telemetry (ART). Discussion: A comprehensive review of the literature supports consideration of cochlear implantation in children for unilateral profound hearing loss after meningitis. Unilateral cochlear implantation has the potential to improve speech understanding in background noise and provide localization ability. Conclusion: Cochlear implantation has the potential to improve overall auditory function in children with single- sided deafness after meningitis. [ABSTRACT FROM AUTHOR]
