摘要

摘要: 人工耳蜗又名电子耳蜗、仿生耳或电子仿生耳,是一种能使重度、极重度感音神经性聋患者重获听力的人工电子装置,也是目前能让患者理解言语的有效方法,对提高患者的生活质量有极大帮助。基于耳蜗的特殊解剖结构,人工耳蜗的性能和设计必须符合耳蜗的形态学特点,通过植入耳蜗内的电极序列,刺激残存的神经节细胞胞体,重建听觉功能。电极设计和电极植入位置是影响植入术后获益的重要因素,测定电极阻抗值是评估人工耳蜗电极状态的有效手段。现结合耳蜗的解剖病理生理学特点对人工耳蜗电极位置与电极阻抗的关系进行综述。

Abstract: Since the first cochlear implant was developed and used in clinical practice, many patients with profound deafness have returned to the world of sound, with the development of modern large-scale integrated circuits and the in-depth study of the anatomical pathophysiology of cochlea, deaf patients have been continuously benefited from it. Electrode is one of the core parts of cochlea implants, the design of the electrode and the placement of the electrode are important factors for patients to benefit from cochlea implantation. Postoperative starting up and debugging are also crucial. Through debugging, the electric stimulation level of each channel can be optimized, which is of great significance for postoperative rehabilitation effect, the magnitude of electrode impedance plays an important role in starting up and debugging. At present, there is no unified conclusion about the relationship between the electrode position and the electrode impedance value. Only when the implanted position and the electrode impedance are normal, can the implanted electrode function be better played.
