This study aimed to evaluate the neural response in double-array cochlear implant as well as to describe the refractory recovery and the spread of excitation functions. In a prospective study 11 patients were implanted with the double-array cochlear implant. Neural response telemetry (NRT) was performed intra-operatively. NRT threshold could be registered in 6 of the 11 patients, at least in one electrode. The remaining five patients did not show measurable neural response intra-operatively. It was noted that although recovery and spread of excitation functions could be recorded in all the tested electrodes with measurable neural responses, the responses were shown to be different from the usual register in patients with other etiologies.
本研究旨在评估双数组人工耳蜗的神经反应，并描述其不应期恢复和兴奋扩散功能。在一项前瞻性研究中，对 11 例患者进行了双数组人工耳蜗植入。术中进行了神经反应遥测术（NRT）。至少在一个电极中，可在 11 例患者中的 6 例中记录到 NRT 阈值。其余 5 例患者术中未记录到可测量的神经反应。虽然在所有可测量神经反应的电极中都可以记录到恢复和兴奋扩散功能，但与其他病因患者的通常记录相比，这些反应表现出不同。
