人工耳蜗植入恢复聋人听觉是近20年来耳科学中一种新技术。随着人工耳蜗植入技术的推广应用,植入材料的耐受性问题受到关注。一、电极植入对耳蜗及听神经的影响 1.理化创伤作用(1—10) 动物实验和人颞骨的组织学研究证明,电极植入是可行的,能获得有效的电听觉及电声效应。但有轻度的局部组织反应,其物理创伤作用与电极部位、电极类型及电极植入的方式与深度密切相关。蜗外电极埋植,包括圆窗龛植电极及蜗内阶外电极,一般
Cochlear implantation to restore hearing in the deaf is a new technique in otology in the past 20 years. With the promotion and application of cochlear implantation technology, the tolerance of implanted materials has drawn attention. First, the impact of electrode implantation on the cochlear and auditory nerve 1. Physical and chemical trauma (1-10) animal experiments and human temporal bone histological studies have shown that the electrode implantation is feasible, to obtain effective electrical auditory and electroacoustic effects. However, there is a slight local tissue reaction, and its physical trauma is closely related to the location of the electrode, the type of electrode and the way of electrode implantation. Cochlear implant electrode, including the round window niche implant electrodes and electrodes outside the pit, in general
