Abstract

Surgery for cochlear implant is a traumatic procedure, with inflammatory responses leading to immediate and delayed intracochlear changes, resulting in newly formed fibrous and bony tissue. This newly formed tissue is thought to affect speech perception with cochlear implants and can also play a role in causing device malfunctioning and soft failures. We present a case of left cochlear implant explantation and reimplantation in a 15-year-old girl, who experienced deterioration of speech perception and device failure associated with osteoneogenesis of the round window, which could represent a cause of cochlear implant failure. To avoid surgical trauma of the cochlear lateral wall, enlarged round window insertion rather than a cochleostomy, soft surgical techniques, and the application of steroids are all important issues to prevent new tissue formation, although special attention should also be given to the trauma of round window borders.
圆窗骨质增生:人工耳蜗植入失败的可能原因?
人工耳蜗植入手术是一种创伤性手术,炎症反应会导致耳蜗内发生即时和延迟的变化,形成新的纤维和骨组织。这种新形成的组织被认为会影响人工耳蜗的言语感知,还可能导致设备故障和软失效。我们介绍了一例为一名 15 岁女孩进行左侧人工耳蜗植入体剥离和再植入手术的病例,她的言语感知能力下降和设备故障与圆窗骨质增生有关,这可能是人工耳蜗植入体故障的原因之一。为避免人工耳蜗侧壁的手术创伤,扩大的圆窗插入而非耳蜗造口术、软性手术技术和类固醇的应用都是防止新组织形成的重要措施,但也应特别注意圆窗边界的创伤。
