Abstract Cochlear implantation is currently the intervention option of choice for many children with auditory neuropathy spectrum disorder (ANSD) who are unable to obtain benefit from conventional amplification. The aim of this study was to review the speech perception and language outcomes for children with ANSD who had received a cochlear implant and highlight specific clinical considerations for working with this population of children with hearing impairment who are being considered for implantation. Finds for the group of 17 children with ANSD using cochlear implants were compared to previously reported outcomes for children with sensori-neural (SN) type hearing loss using cochlear implants. Two children, identified with cochlear nerve deficiency pre-operatively, received no useful auditory percepts from their cochlear implant and discontinued device use. The remaining children demonstrated speech perception and language outcomes comparable to those observed for SN hearing loss peers using cochlear implants. This paper highlights a number of considerations for clinicians to be aware of and the importance of careful counseling pre-operatively regarding the potential for less-than-optimal outcomes, particularly for those children identified with cochlear nerve deficiency.

Objective: To assess bimodal auditory performance in children with a cochlear implant (CI) and contralateral auditory brainstem implant (ABI). Methods: This is a retrospective case review performed at a tertiary referral center. Four patients with cochlear nerve deficiency initially underwent cochlear implantation but were not benefiting from their devices and underwent ABI in the contralateral ear. The main outcome measures included age-appropriate speech perception and production assessments. Results: Three subjects performed better on their auditory perception assessments using both of their devices than with either device alone. One subject had only preliminary outcomes, but subjectively performed best with both devices. Conclusions: We observed continued improvement in CI performance over time, even if no benefit was evident before the decision for ABI. This could suggest that ABI and CI have a synergistic effect, or it could simply be the adaptive ability of the developing brain to utilize the signals coming from these devices. There is preliminary evidence to support choosing the ear contralateral to the CI for an ABI in a pediatric patient with bilateral cochlear nerve deficiency.

Objective: To characterize the prevalence, imaging characteristics, and cochlear implant candidacy of pediatric patients with single-sided deafness (SSD). Methods: An audiometric database of patients evaluated at a large tertiary academic medical center was retrospectively queried to identify pediatric patients (<18 years old) with SSD, defined as severe to profound sensorineural hearing loss in one ear and normal hearing in the other. Medical records of identified patients were reviewed to characterize the prevalence, etiology, and cochlear implant candidacy of pediatric patients with SSD. Results: We reviewed audiometric data obtained from 1993 to 2018 for 52,878 children at our institution. 191 (0.36%) had the diagnosis of SSD. Cochlear nerve deficiency (either hypoplasia or aplasia) diagnosed on MRI and/or CT was the most common etiology of SSD and was present in 22 of 88 (25%) pediatric SSD patients with available imaging data. 70 of 106 (66%) pediatric SSD patients with available imaging had anatomy amenable to cochlear implantation. Conclusions: Pediatric SSD is a rare condition and the most common etiology based on radiology is cochlear nerve deficiency. High resolution imaging of the temporal bone is essential to determine cochlear nerve morphology prior to consideration of cochlear implantation.
