人工耳蜗再植入的临床再认识与规范化管理策略

Clinical Reconsideration and Standardized Management Strategies for Cochlear Reimplantation

摘要:

人工耳蜗植入已成为重度、极重度感音神经性听力损失患者听觉重建的常规技术。随着受植人群扩大、植入年龄前移及设备使用年限延长,再植入问题逐渐从少见的补救手术转变为人工耳蜗长期管理中的重要内容。再植入的临床难点不在于“是否更换一台设备”,而在于准确判断听觉中断或获益下降的原因,区分设备故障、局部感染与皮瓣问题、电极位置异常、内耳解剖条件及老旧设备维护困难等不同场景。对于疑似软失败、儿童听觉行为退步及感染相关病例,尤其需要避免过早手术或长期延误两个极端。本文从再植入的概念边界、常见临床场景、术前判断、病因导向手术及术后功能管理等方面进行阐述,强调以听觉连续性和长期可用听力为核心,推动人工耳蜗再植入的规范化、个体化管理。

Abstract:

Cochlear implantation has become a routine intervention for auditory rehabilitation in patients with severe-to-profound sensorineural hearing loss. With the expansion of the implanted population, earlier implantation, and prolonged device use, cochlear reimplantation is increasingly recognized as an important component of long-term cochlear implant care. The clinical challenge is not simply whether to replace a device, but how to identify the cause of interrupted or declining auditory benefit and distinguish device failure, infection or flap compromise, electrode-related problems, inner ear anatomical factors, and difficulty maintaining legacy devices. In suspected soft failure, pediatric behavioral regression, and infection-related cases, clinicians should avoid both premature surgery and excessive delay. This article discusses the conceptual boundaries, common clinical scenarios, preoperative judgment, cause-oriented surgical management, and postoperative functional follow-up of cochlear reimplantation. The goal is to emphasize continuity of auditory input and sustainable functional hearing, and to support more standardized and individualized management.
