Use of the FLEX 28 Dexamethasone-Eluting Cochlear Implant Electrode in Electric-Acoustic Stimulation: A Case Report.

ABSTRACT: Background/Objectives: During and after electric-acoustic stimulation (EAS) surgery (as well as regular cochlear implant surgery), the oral and/or intravenous administration of steroids is recommended to prevent acute inflammatory reactions and subsequent fibrosis. However, the effect does not last long. Therefore, with the hope of providing a sustained effect, a new dexamethasone (DEX)-eluting electrode (FLEX28 DEX) has recently been developed. Methods: A case study was performed at Shinshu University in February 2024 in which a DEX-eluting electrode array was utilized for a patient presenting with high-frequency hearing loss with a defined etiology (hearing loss due to a mitochondrial m.1555A > G variant). Results: Residual hearing was well preserved after EAS surger
