Comparative Analysis of Cortical Auditory Evoked Potential in Cochlear Implant Users

Conclusions: This study successfully compared aCAEP and eCAEP in CI users. Both acoustic and electrical P1–N1–P2 recordings obtained were clear and reliable, with good correlation. Latency increased with decreasing stimulation level, while amplitude decreased. eCAEP is potentially a better option to verify speech detection at the cortical level because it (1) uses direct stimulation and therefore creates less interference and delay of the sound processor and (2) creates more flexibility with the recording setup and stimulation setting. As such, eCAEP is an alternative method for CI optimization.
