Abstract: Objective To investigate the adjustment methods and evaluation for children after cochlear implantation. Methods 6 children after artificial cochlear implantation were debugged by subjective psychological physical test, objective methods such as electricity induced composite action potential (ECAP), electrically evoked stapedius reflex threshold (ESRT) and electrically evoked auditory brainstem response (EABR). Results All the children got satisfied data. Conclusion For the children after cochlear implantation, objective methods such as ECAP, ESRT, EABR combined with subjective psychological physical test all together are helpful to obtain accurate threshold.
