Abstract：
OBJECTIVE: Trigeminal Neuralgia (NT) is a common pathology in Neurosurgery. It can be classified as idiopathic or secondary to other pathologies, such as Multiple Sclerosis (MS). Several surgical treatments have been described, some of them being replaced by more modern techniques. Partial sensory rhizotomy (PSR), described by Dandy is a technique replaced by other techniques due to its permanent side effects. We present our experience with this technique in patients with recurrent NT.
METHODS: A retrospective review is carried out on five patients who underwent surgery at our center from 2018 to 2023 using the PSR technique.
RESULTS: All the patients intervened showed significant clinical improvement, except one patient who required reintervention due to uncontrolled pain. According to the Barrow Neurological Institute (BNI) scale, 80% (4/5) of patients showed improvement from grade V to grades I/II except for one of them. This patient suffered from MS. Additionally, one patient presented a corneal ulcer after surgery due to impairment of the corneal reflex.
CONCLUSIONS: In our experience, PSR is a valid treatment option in selected patients with recurrent TN. It has a low incidence of complications with an adequate surgical technique and anatomical knowledge of the region. To the best of our knowledge, we are one of the few centers in Spain to publish our results with PSR in the last ten years. We report good results in pain control withdrawing medication in 80% (4/5) of the operated patients.

摘要：
目的：三叉神经痛（NT）是神经外科的常见病理。它可以分为特发性或继发于其他疾病，例如多发性硬化症(MS)。已经描述了几种手术治疗方法，其中一些被更现代的技术所取代。部分感觉根切断术（PSR），Dandy描述的是一种由于其永久副作用而被其他技术取代的技术。我们介绍了这种技术在NT复发患者中的经验。
方法：对2018年至2023年在我们中心使用PSR技术进行手术的六名患者进行了回顾性审查。
结果：所有介入治疗的患者临床症状明显改善，除了一名因疼痛失控而需要再次干预的患者。根据巴罗神经研究所（BNI）的量表，80％（4/5）的患者显示出从V级到I/II级的改善，其中一名除外。这个病人患有MS。此外,1例患者因角膜反射受损,在手术后出现角膜溃疡.
结论：根据我们的经验，PSR是选择患有复发性TN的患者的有效治疗选择。具有足够的手术技术和该区域的解剖学知识，其并发症发生率低。据我们所知,在过去的十年中，我们是西班牙为数不多的发布PSR结果的中心之一。在我们的研究中,我们报告67%(4/6)的手术患者在疼痛控制中停用药物治疗效果良好.
