Abstract

Introduction: We report an unusual case of cochlear implant complication and eventual explantation secondary to an allergic reaction to silicone.

Case report: A 62-year-old man who underwent cochlear implantation for asymmetric hearing loss developed an allergic response to the implant within a few weeks of the surgery. This led to subsequent explantation. Patch testing using the various parts of the implant revealed a hypersensitive response to the silicone component of the receiver stimulator. There have only been 6 reported cases of cochlear implant explantation secondary to allergic reactions to cochlear implants. The inflammatory reaction has been to the silicone component of the cochlear implant found in the silicone used in Cochlear America's implants.

Conclusion: Although rare, it's important to be aware of delayed hypersensitivity reactions to the silicone component of a cochlear implant. Attention should be made to associate symptoms such as pruritis, urticaria and loss of hair as symptoms and signs of possible allergic reaction to the implanted component. Steroids may help to alleviate symptoms; however, symptoms have been shown to recur after cessation of steroids. Treatment requires the removal of the device.

硅胶过敏可导致人工耳蜗植入并发症和切除：病例报告。

导言：我们报告了一例不寻常的人工耳蜗植入并发症病例，该病例最终因对硅胶过敏而导致人工耳蜗移植手术失败：一名 62 岁的男子因不对称听力损失接受了人工耳蜗植入手术，术后几周内出现了对植入物的过敏反应。这导致了随后的移植手术。使用植入体各部分进行的贴片测试表明，他对接收器刺激器的硅酮成分过敏。目前仅有 6 例因对人工耳蜗植入物过敏而导致人工耳蜗植入物取出的报告。炎症反应是针对人工耳蜗的硅酮成分，在美国科利耳公司的植入体中使用的硅酮就含有这种成分：结论：尽管罕见，但必须警惕对人工耳蜗硅酮成分的迟发性超敏反应。应注意将瘙痒症、荨麻疹和脱发等症状与可能对植入物过敏的症状和体征联系起来。类固醇可能有助于缓解症状，但停用类固醇后症状可能会复发。治疗需要取出装置。

期刊介绍： Cochlear Implants International was founded as an interdisciplinary, peer-reviewed journal in response to the growing number of publications in the field of cochlear implants. It was designed to meet a need to include scientific contributions from all the disciplines that are represented in cochlear implant teams: audiology, medicine and surgery, speech therapy and speech pathology, psychology, hearing therapy, radiology, pathology, engineering and acoustics, teaching, and communication. The aim was to found a truly interdisciplinary journal, representing the full breadth of the field of cochlear implantation.
