With growing interest and acceptance of peripheral nerve stimulation (PNS) approach, there is now an increasing need in developing clear procedural details to resolve frequent complications and minimize associated tissue injury. Migration and suboptimal positioning of PNS electrodes are one of the most commonly observed complications of PNS approach.
We present a simple technique for repositioning a supraorbital electrode using retrograde insertion of introducer needle that allows one to place percutaneous (cylindrical) PNS electrode into appropriate anatomical location with minimal additional injury to surrounding tissues.
This approach has been successfully used in multiple cases. An illustrative case of electrode revision with proposed technique is described in detail.
This technically simple approach to repositioning of cylindrical supraorbital electrodes using retrograde needle insertion eliminates the need for a more elaborate and invasive procedure. The technique can be used for electrode repositioning in most PNS applications.
随着对外周神经刺激 (PNS) 方法的兴趣和接受度不断提高，现在越来越需要制定明确的程序细节来解决常见并发症并尽量减少相关组织损伤。PNS 电极的迁移和位置不当是 PNS 方法最常见的并发症之一。
我们提出了一种使用逆行插入导入器针重新定位眶上电极的简单技术，该技术允许将经皮（圆柱形）PNS 电极放置到适当的解剖位置，同时对周围组织的损伤最小。
该方法已在多例患者中成功应用。详细描述了使用该技术进行电极修正的一个说明性病例。
这种使用逆行针插入重新定位圆柱形眶上电极的技术简单，避免了更复杂和有创的手术。该技术可用于大多数 PNS 应用中的电极重新定位。
