Percutaneous balloon compression is a safe and effective therapeutic modality for trigeminal neuralgia. It is widely recognized that the pear-shaped balloon is the key to the success of the procedure. This study aimed to analyze the effect of different pear-shaped balloons on the duration of the treatment outcome. In addition, the relationship between individual variables and the duration and severity of complications was analyzed. The clinical data and intraoperative radiographs of 132 patients with trigeminal neuralgia were reviewed. We classify pear-shaped balloons into type A, type B, and type C balloons depending on the size of their heads. The collected variables were correlated with prognosis by univariate and multivariate analyses. The efficiency of the procedure was 96.9%. There was no significant difference in pain relief rates between the different pear-shaped balloons. Median pain-free survival time was longer for type B and C balloons, which were significantly different from type A balloons. In addition, pain duration also was a risk factor for recurrence. There was no significant difference in the duration of numbness between the different types of pear-shaped balloons, but type C balloons resulted in longer-lasting masticatory muscle weakness. Duration of compression and balloon shape can also significantly influence the severity of complications. Different pear-shaped balloons have been shown to have a significant effect on the efficacy and complications of the PBC procedure, with type B balloons (head ratio: 10–20%) appearing to be the ideal pear shape. However, its clinical application remains to be validated.

经皮球囊压迫是治疗三叉神经痛安全有效的方法。人们普遍认为，梨形球囊是手术成功的关键。本研究旨在分析不同梨形球囊对治疗结果持续时间的影响。此外，分析了个体变量与并发症持续时间和严重程度之间的关系。回顾132例三叉神经痛患者的临床资料和术中X线片。我们将梨形气球根据头部大小分为A型、B型和C型气球。收集的变量通过单变量和多变量分析与预后相关。该程序的效率为 96.9%。不同梨形气球之间的疼痛缓解率没有显着差异。B 型和 C 型球囊的中位无痛生存时间更长，这与 A 型球囊有显着差异。此外，疼痛持续时间也是复发的危险因素。不同类型的梨形气球之间的麻木持续时间没有显着差异，但 C 型气球导致咀嚼肌无力的持续时间更长。压缩持续时间和球囊形状也会显着影响并发症的严重程度。不同的梨形球囊已被证明对 PBC 手术的疗效和并发症有显着影响，B 型球囊（头部比例：10-20%）似乎是理想的梨形球囊。然而，
