The authors describe a simple and low-cost technique for image-guided cannulation of the foramen ovale during treatment of medically refractory trigeminal neuralgia using percutaneous radiofrequency rhizotomy. Computed tomography-guided neuronavigation and the noninvasive ear, nose, and throat Small Active Frame system were applied for visualization of cannulation of the foramen ovale in the awake patient. Use of invasive head-clamp fixation was unnecessary. Three patients were treated using this technique in which the foramen ovale was reached using a single tract. No adverse effects of this technique were reported. The potential benefits and disadvantages of this method are presented.
作者描述了一种在经皮射频半月神经节根切断术治疗药物难治性三叉神经痛时引导卵圆孔穿刺的简单、低成本技术。计算机断层扫描引导神经导航和非侵入性耳鼻喉科 Small Active Frame 系统用于在清醒患者中可视化卵圆孔穿刺。不需要使用有创的头夹固定。使用该技术治疗了 3 名患者，其中通过单个通道到达卵圆孔。该技术无不良影响。本文介绍了该方法的潜在优缺点。
