Among them, 32 cases experienced FNS after CI, and another 32 cases were selected from 817 pediatric implantees by stratified random sampling. The width of the BCNC, the status of the cochlear nerve (CN) and the internal auditory canal (IAC), T level, and C level were compared and analyzed.

Adjustment of the C levels and\/or pulse width and switching off offending electrodes were attempted to eliminate FNS, with a 75.0% success rate.
