Abstract:
OBJECTIVE To study the relationship between frequency specific free-field tone burst cortical auditory evoked potentials(CAEP)and aided behavioral audiometry to provide rapid,reliable insights for predicting hearing intervention efficiency in hard to cooperate cochlear implant patients.METHODS The study comprised of 22 cochlear implant pediatric patients(22 ears)free-field tone burst CAEP P1 response thresholds,free-field behavioral thresholds determined within the group across frequencies 0.5,1,2 and 4 kHz were collected for correlation analysis.RESULTS The free-field tone burst CAEP P1 response thresholds and free-field behavioral audiometric thresholds in cochlear implant pediatric patients for testing frequencies 0.5,1,2,4 kHz were compared and r correlation coefficients found were 0.567,0.670,0.637 and 0.762 across the frequencies respectively(P<0.01).The mean difference between free-field CAEP P1 response threshold and free-field behavioral thresholds for cochlear implant patients differ by 5-8 dB with statistical significance.CONCLUSION Free-field tone burst CAEP can be used for cochlear implant programming validation in patients that fail to cooperate in behavioral testing,thus is applicable in cochlear implant programming clinical practice.
