摘　　要：目的探讨应用CT分层扫描测量射频温控热凝术治疗三叉神经痛时穿刺针进入卵圆孔的深度。方法统计121例三叉神经痛患者行射频温控热凝术时的CT分层扫描图,并计算穿刺深度。结果121例CT分层扫描统计结果,穿刺深度最浅为0.4cm,最深为1.6cm,平均进针深度为0.8cm。结论CT定位下能正确掌握穿刺深度,穿刺深度为0.8cm以内时可避免对三叉神经第一、二支损伤;穿刺深度为1.2～1.5cm可避免对三叉神经第一支的损伤。Objective To control the puncture depth properly and avoid the complications,CT scan was used to measure the depth as the puncture needle perforated through the foramen ovale.Methods Analysis of the CT scan diagrams of121cases suffering from TN cured by RFT,and measuring the puncture depth.Results The average puncture depth was0.88cm,the maximum was1.6cm,and the minimum was0.4cm.Conclusion The puncture depth can be manipulated correctly by CT location,the second and third branches can be avoided to be damaged within0.8cm,and the first branch can be avoided to be injured between1.2cm and1.5cm.
