Objective: Cochlear implantation is the process of inserting a very small and soft electrode into the intrascalar. During surgery, the electrode can be kink or failure, and the internal structure of the cochlea can be damaged by the electrode tip. The study aims to retrospectively analyze the electrode-to-tissue impedance(electrode impedance), voltage compliance, stimulation artifact, electrically compound action potential(ECAP) implemented during the surgery to examine the clinical implication with a literature review. Participants & Method: The participants are three 70 to 76-year-old male implantee to whom MedEl s synchrony(Flex 28) implanted to the left ear. Results: The electrode impedance was observed in 1.69 to 8.25 ㏀, the voltage compliance was observed in 0.52 to 2.38 V, and the inter-channel voltage compliance be ranging from 0.11 to 0.38 V, respectively. In each channels, the baseline of the ECAP waveform was consistently observed, and the threshold of ECAP was observed to be ranging from 7.7 to 26.1 qu. Conclusion: In conclusion, intraoperative monitoring of electrode integrity during the surgery, the malfunctioning of the device together with the various issue that stem the surgery process can be discovered, hence resulting in obtaining valuable proof in solving the issues detected.
