听觉诱发电位在人工耳蜗植入全流程中的应用OA

Cochlear implantation(CI)are one of the most effective interventions for patients with severe-to-profound sensorineural hearing loss and insufficient hearing aid benefit.Auditory evoked potential(AEP)underpins the whole CI workflow—preoperative assessment,intraoperative monitoring,postoperative efficacy evaluation,and rehabilitation management.Preoperatively,acoustic AEPs,including otoacoustic emission(OAE),electrocochleography(ECochG),auditory brainstem response(ABR),tone-burst ABR(TB-ABR),auditory steady-state response(ASSR),and 40Hz auditory event-related potential(40Hz AERP),are used to assess hearing loss severity/nature,lesion location,as well as the integrity and maturity of the auditory pathway.Intraoperatively,real-time feedbacks from ECochG,electrically evoked compound action potential(ECAP),electrically evoked ABR(EABR),and electrically evoked stapedius reflex(ESR)facilitate precise electrode insertion,residual hearing preservation,and postoperative outcome prediction.Postoperatively,ECAP,EABR,and cortical auditory evoked potentials(CAEP)form an objective framework for CI fitting and efficacy evaluation.A multimodal assessment strategy centered on AEPs,integrated with imaging,patient-reported outcomes,and behavioral audiometry,enables individualized precision diagnosis and treatment for CI patients.
