Improvements in device technology, surgical technique, and patient outcomes have resulted in a broadening of cochlear implantation criteria to consider those with increasing levels of useful low-to-mid frequency residual acoustic hearing. Residual acoustic hearing allows for the addition of a hearing aid (HA) to complement the cochlear implant (CI) and has demonstrated enhanced listening outcomes. However, wide inter-subject outcome variability exists and thus identification of contributing factors would be of clinical interest and may aid with pre-operative patient counselling. The optimal fitting procedure and frequency assignments for the two hearing devices used in combination to enhance listening outcomes also remains unclear. The understanding of how acoustic and electric speech information is fundamentally combined and utilised by the listener may allow for the optimisation of device fittings and frequency allocations to provide best bimodal and electric-acoustic stimulation (EAS) patient outcomes. This article will provide an overview of contributing factors to bimodal and EAS listening outcomes, explore areas of contention, and discuss common study limitations.
设备技术、手术技术和患者预后的改善使得耳蜗植入标准扩大，考虑到越来越多的具有有用的低中频残余声觉的患者。残余声觉允许添加助听器 (HA) 来补充耳蜗植入 (CI)，并已证明听力结果得到增强。然而，广泛的个体间结果变异性存在，因此确定促成因素将具有临床意义，并可能有助于术前患者咨询。用于增强听力结果的两种听力设备的最佳适配程序和频率分配仍然不清楚。了解听众如何从根本上组合和利用声觉和电觉信息，可能允许优化设备适配和频率分配，以提供最佳的双耳和电声刺激 (EAS) 患者结果。本文将概述双耳和 EAS 听力结果的影响因素，探讨争议领域，并讨论常见的研究局限性。
