OBJECTIVE: There are a variety of minimally invasive interventional treatments for trigeminal neuralgia, and the efficacy evaluation is different. The preferred treatment scheme is still controversial. This study aims to investigate the differences in treatment effects between patients with primary trigeminal neuralgia (PTN) treated with percutaneous balloon compression (PBC) for the first intervention and patients with pain recurrence after radiofrequency thermocoagulation (RT) who then received PBC for PTN, and to offer clinicians and patients more scientifically grounded and precise treatment alternatives.
METHODS: We retrospectively analyzed 103 patients with PTN admitted to the Department of Pain Management of the Second Affiliated Hospital of Guangxi Medical University from January 2020 to December 2021, including 49 patients who received PBC for the first time (PBC group) and 54 patients who received PBC for pain recurrence after RT (RT+PBC group). General information, preoperative pain score, intraoperative oval foramen morphology, oval foramen area, balloon volume, duration of compression, and postoperative pain scores and pain recurrence at each time point on day 1 (T1), day 7 (T2), day 14 (T3), 1 month (T4), 3 months (T5), and 1 year (T6) were collected and recorded for both groups. The differences in treatment effect, complications and recurrence between the 2 groups were compared, and the related influencing factors were analyzed.
RESULTS: The differences of general information, preoperative pain scores, foramen ovale morphology, foramen ovale area, T1 to T3 pain scores between the 2 groups were not statistically different (all P>0.05). The balloon filling volume in the PBC group was smaller than that in the RT+PBC group, the pain scores at T4 to T6 and pain recurrence were better than those in the RT+PBC group (all P<0.05). Pain recurrence was positively correlated with pain scores of T2 to T6 (r=0.306, 0.482, 0.831, 0.876, 0.887, respectively; all P<0.01).
CONCLUSIONS: The choice of PBC for the first intervention in PTN patients is superior to the choice of PBC after pain recurrence after RT treatment in terms of treatment outcome and pain recurrence.
目的: 三叉神经痛有多种微创介入治疗方式,各种方法的疗效不同,对于首选治疗方案仍有争议。本研究旨在比较原发性三叉神经痛(primary trigeminal neuralgia,PTN)患者首次接受经皮球囊压迫术(percutaneous balloon compression,PBC)介入治疗和射频热凝术(radiofrequency thermocoagulation,RT)治疗后疼痛复发再接受PBC在治疗效果等方面的差异,以期为患者提供更科学、精准的治疗方案。方法: 回顾性分析2020年1月至2021年12月广西医科大学第二附属医院疼痛科收治的103例PTN患者的临床资料,其中首次接受PBC治疗的患者49例(PBC组),RT术后疼痛复发接受PBC治疗的患者54例(RT+PBC组)。比较2组患者术前疼痛评分,术中卵圆孔形态、卵圆孔面积、球囊容积、压迫时长,术后第1天(T1)、第7天(T2)、第14天(T3)、1个月(T4)、3个月(T5)、1年(T6)各时间点的疼痛评分及疼痛复发情况等的差异,并分析术后复发情况与疼痛评分的相关性。结果: 2组间一般资料、术前疼痛评分、卵圆孔形态、卵圆孔面积、T1~T3疼痛评分的差异均无统计学意义(均P>0.05)。与RT+PBC组比较,PBC组球囊充盈容积较小,T4~T6的疼痛评分较低,疼痛复发例数较少(均P<0.05),疼痛复发情况与T2~T6的疼痛评分均呈正相关(分别r=0.306、0.482、0.831、0.876、0.887,均P<0.01)。结论: PTN患者首次介入治疗建议选择PBC,在治疗效果和疼痛复发情况等方面均优于RT治疗后疼痛复发再选择PBC治疗。.
