Background. Radiofrequency of the Gasserian ganglion can be used for ophthalmic herpetic neuralgia (OHN), but it is associated with complications. This study aimed to use the supraorbital nerve for computed tomography- (CT-) guided radiofrequency thermocoagulation to treat refractory OHN. Methods. This was a retrospective case series study of patients with simple or combined OHN treated at our hospital between 06/2012 and 06/2018. The numerical rating score (NRS), spontaneous pain, allodynia, gabapentin dosage, paracetamol/oxycodone dosage, patient global impression of change (PGIC) score, Barrow numbness score, postoperative 360-day recurrence rate, and complications were recorded before the operation and at 1, 30, 90, 180, and 360 days after the operation. Results. Compared with baseline, the NRS was decreased, and PGIC was increased at postoperative 1, 30, 90, 180, and 360 days, and the gabapentin and paracetamol oxycodone doses at postoperative 30, 90, 180, and 360 days were decreased (all ). Compared with 1 day after the operation, numbness was decreased at 30, 90, 180, and 360 days after the operation (). Compared with baseline, the number of patients with allodynia at each time point after the operation was decreased (), but without a difference for spontaneous pain (). No subjects showed drooping eyelid, corneal ulcers, eyeball damage, decreased vision, and other severe complications. Conclusion. CT-guided supraorbital nerve radiofrequency thermocoagulation for the treatment of OHN can effectively relieve pain and reduce the dose of analgesics, without any serious complication. This study suggests that this technique is feasible and applicable to clinical practice.

眶上神经射频治疗带状疱疹眼球引起的严重神经痛

背景。Gasserian神经节的射频可用于眼科疱疹性神经痛（OHN），但与并发症相关。这项研究旨在利用眶上神经进行计算机断层扫描（CT）引导的射频热凝治疗难治性OHN。方法。这是一项回顾性病例系列研究，研究对象是06/2012至06/2018年间在我院接受过简单或联合OHN治疗的患者。在手术前和手术前记录数值评分（NRS），自然疼痛，异常性疼痛，加巴喷丁剂量，扑热息痛/羟考酮剂量，患者总体变化印象（PGIC）评分，巴罗麻木评分，术后360天复发率以及并发症。手术后1、30、90、180和360天。结果。与基线相比，术后1、30、90、180和360天的NRS降低，PGIC升高，而术后30、90、180和360天的加巴喷丁和扑热息痛羟考酮剂量降低（所有）。与术后1天相比，术后30、90、180和360天的麻木感有所降低（）。与基线相比，术后每个时间点的异常性疼痛患者数量减少了（），但自发性疼痛没有区别（）。没有受试者表现出下垂的眼睑，角膜溃疡，眼球损伤，视力下降和其他严重并发症。结论。CT引导的眶上神经射频热凝治疗OHN可有效缓解疼痛并减少镇痛药的剂量，而无任何严重并发症。这项研究表明，该技术是可行的，并适用于临床实践。
