Monocentric, prospective study to investigate whether concomitant support of cochlear implant (CI) patients by CI-trained otolaryngologists and application of a standardized head bandage can minimize potential complications during magnetic resonance imaging (MRI).
Thirty-seven patients with 46 CIs underwent MRI with a prophylactic head bandage. All participants and the otolaryngologist at the CI center completed pre- and post-MRI questionnaires documenting body region scanned, duration of MRI and bandage wear, field strength during the scan, and any complications. If pain was experienced, it was assessed using a visual analog scale (1-10).
MRI was performed without adverse events in 37.8% of cases. Magnet dislocation requiring surgical revision occurred in 2% of cases. Pain was reported in 86% of cases, often due to the tightness of the dressing. Patients with rotating, MRI-compatible magnets reported significantly less pain than participants with older-generation implants. In 11% of cases, the MRI was discontinued.
Serious complications during MRI in cochlear implant patients are rare. Pain is the most common adverse event, probably mainly due to the tight bandage required by most implant types. With newer generations of magnets, these patients experience less pain, no dislocation of the magnets, and no need for bandaging. Although magnet dislocation cannot be completely prevented in older generations of implants, it appears to be reduced by good patient management, which recommends examination under the guidance of physicians trained in the use of hearing implants.
单中心前瞻性研究，旨在探讨是否可以通过经耳蜗植入（CI）培训的耳鼻喉科医生为 CI 患者提供同时支持，并应用标准化头带，将潜在并发症最小化。
37 名患者的 46 个 CI 接受了预防性头带的 MRI。所有参与者和 CI 中心的耳鼻喉科医生都填写了预扫描和后扫描问卷，记录扫描的身体区域、MRI 和头带佩戴时间、扫描期间的磁场强度，以及任何并发症。如果有疼痛，用视觉模拟量表（1-10）进行评估。
MRI 无不良事件发生的占 37.8%。2%的病例发生磁铁脱位，需要手术修复。86%的病例报告有疼痛，通常是由于敷料过紧引起的。使用旋转、MRI 兼容磁铁的患者比使用较旧一代植入物的患者报告的疼痛明显减少。11%的病例中止了 MRI。
在耳蜗植入患者中，MRI 期间发生严重并发症的情况很少见。疼痛是最常见的不良事件，可能主要是由于大多数植入物类型都需要紧的头带。使用新一代磁铁，这些患者的疼痛减轻，磁铁脱位减少，无需包扎。虽然在较旧一代的植入物中无法完全防止磁铁脱位，但通过良好的患者管理，似乎可以减少脱位的发生，患者管理建议在接受过听力植入物使用培训的医生的指导下进行检查。
