Recovery function after 12 months of cochlear implant use

The outcomes in cochlear implants' cases depend on several factors, including the condition of and propagating of the stimulus in the auditory nerve. The auditory nerve’s time constant can provide temporal information about the auditory nerve's behaviour when facing cochlear implant stimuli.We recruited cochlear implanted children with intraoperative neural response, and the recovery functionwas evaluated usingcommercially available cochlear implant software. The data were collected intraoperatively and repeated twice at 12 months after surgery.We found that relative recovery time increases over 12 months of cochlear implant use. Our results also show that the profile of ECAP-REC responses is significantly longer in the postoperative measure.The test-retest reproducibility of evoked compound action potential recordings proved to be reliable.Our study promotes the clinical use of the relative refractory period of the auditory nerve for programming the cochlear implant. It could also be a tool for audiologists while performing prognosis assessments of the changes in cochlear implants function during recovery. The response pattern after 12 months of cochlear implants use should be further studied.New studies should focus on increasing the clinical use of objective measures trustworthy to improve speech perception in cochlear implants users.
