[Study on auditory event related potential with cochlear and hearing aid meanwhile].
Abstract
OBJECTIVE: Study the changes of auditory event related potential (ERP), as well as evaluate objectively auditory effect of both ears, when cochlea implant and hearing aid are applied meanwhile. METHOD: Put 6 samples into 2 different groups: CI&HA (cochlea implant and hearing aid meanwhile) group and CI (cochlea implant only) group. Test the latent periods of P300, N200, N100, and the amplitude of P300, which are the main parts of ERP. RESULT: All of the latent periods of P300 and N200 in CI& HA group were shorter, compared with those in CI group respectively. The difference was significant. In CI&HA group, the average latent period of P300 was (388.96 +/- 62.61) ms, the average amplitude was (13.69 +/- 3. 26) microV, the average latent period of N200 was (267.00 +/- 45.43) ms, the average latent period of N100 was (94.58 +/- 9.10) ms. In CI group, the average latent period of P300 was (412.08 +/- 54.32)ms, the average amplitude was (12.23 +/- 2.97) microV, the average latent period of N200 was (289.21 +/- 37.40) ms, the average latent period of N100 was (99.381+/- 13.15) ms. CONCLUSION: When both ears use cochlear and hearing aid meanwhile, which are under different working patterns; the central progress has no resistance. Thus, auditory effect could be obtained in both ears.
