Abstract
OBJECTIVE: To investigate the evaluation value of electrically evoked auditory brainstem response (EABR) monitoring before cochlear implantation in patients with cochlear nerve defects (CND). METHODS: A total of 54 patients with cochlear nerve defects who underwent cochlear implantation in our hospital from 2011 to 2018 were selected as the CND group, and 20 patients with normal cochlear implantation were selected as the control group. The preoperative audiological characteristics, EABR characteristics and follow-up neural response telemetry results of the two groups were retrospectively analysed, and the preoperative EABR threshold and initiation C value were subjected to linear regression and correlation analysis. RESULTS: The EABR waveform of the CND group was significantly different from the control group in terms of average wave V threshold, average dynamic range and V-wave I/O curve slope (P < 0.05). Average C value and dynamic range had a statistically significant difference from the control group (P < 0.05). Statistically significant positive correlations were found between the EABR threshold and C value, wave V I/O slope and postoperative category of auditory perception (P < 0.05). CONCLUSIONS: The EABR test can be used to evaluate the auditory pathway function before cochlear implantation and its postoperative effect in patients with CND.
