Cochlear Implant Use Remains Consistent Over Time in Children With Single-Sided Deafness

OBJECTIVES: To measure the acceptance of a cochlear implant by children with single-sided deafness (SSD) using datalogging technology in the cochlear implant processor. DESIGN: Datalogs from follow-up clinical audiology appointments for 23 children with SSD were extracted from their cochlear implant processors ranging from 1 to 8 visits (M = 3.74, SD = 1.79). The number of hours the cochlear implant was in use per day, the number of times the coil disconnected from the internal device, and the percentage of daily cochlear implant use in different auditory environments were collected from the datalogs. Linear mixed-effects regressions were used to analyze the relationship between age, hearing experience, cochlear implant use, and coil-offs per day. Nonlinear regressions were conducted to evaluate cochlear implant use in different environments. RESULTS: Children with SSD wore their cochlear implants for 6.22 (SD = 2.81; range = 0.0004 to 14.74) hours per day on average. No significant change in cochlear implant use was seen as the children grew older or gained more hearing experience. As hearing experience increased, the number of coil-offs per day was reduced. Preschoolers spent more time in "music" and "speech" and less time in "noise" and "quiet" than older and younger children while older children spent more time in "speech-in-noise." CONCLUSIONS: Children with SSD consistently wear their cochlear implants. However, the auditory environments to which they are exposed vary over time. Regular cochlear implant use by this population suggests that it does not detract from a normal-hearing ear and that children with SSD appreciate access to bilateral input.
