Emerging Technologies and Concepts for Cochlear Implantation (2023 AMW) Session
2023 AAO-HNSF Annual Meeting & OTO Experience
PROGRAM DESCRIPTION: This session will highlight emerging concepts in cochlear implantation that improve clinical outcomes including preservation of low frequency hearing and implantation of patients with unilateral hearing loss. Data will be presented that demonstrate enhanced central auditory processing and hearing in complex listening environments with preserved low frequency hearing. We will discuss how new technologies help develop individualized surgical plans based on pre-operative imaging parameters (e.g. cochlear length), genetic profile, etiology of hearing loss, and age. We will discuss the clinical use of technologies that have recently been introduced that enable improved preservation of cochlear structures and customized rehabilitation strategies. These include pre-operative and post-operative image based planning tools, intra-operative and post-operative electrophysiological measures (e.g. electrocochleography and advanced impedance measures), robotics assisted electrode array insertion, dexamethasone eluting electrodes, and customized electrode arrays. Integration of these technologies to develop a comprehensive strategy will be demonstrated. Finally, we will conclude by highlighting technologies currently in preclinical development such as novel biomaterials, immunomodulatory drugs, and approaches to preserve neural function.OUTCOME OBJECTIVE 1: Recognize the advantages of preserving low frequency hearing for a patient to process and understand speech in complex listening environments.OUTCOME OBJECTIVE 2: Implement recently introduced clinical technologies such as electrocochleography, robotics assistance, and imaging tools into a comprehensive strategy to preserve cochlear structure and function.OUTCOME OBJECTIVE 3: Describe emerging concepts and strategies that are working their way into clinical practice and are aimed at enhancing the cochlear environment and function.BACKGROUND STATEMENT: Cochlear implant technology is rapidly changing. In parallel, criteria for implantation are expanding rapidly. These dynamics highlight the critical need for surgeons and audiologist to be abreast of the newest concepts, strategies, and technologies that lead to optimal outcomes.
