摘要
目的为临床经额颧角穿刺蝶腭神经节(PPG)阻滞提供影像解剖数据。方法在需行PPG阻滞6例患者的MRI影像图像下定位蝶腭神经节并确定相关骨性标志。在142例(284侧)患者的CT影像资料中模拟穿刺,对穿刺相关的解剖数据进行影像学测量。结果额颧角位于距眶外缘(17.01±2.44)mm的平行线与距眶下缘(7.54±3.02)mm的平行线交点处。经额颧角穿刺针与穿刺平面的正中线的夹角为(68.41±4.19)°,冠状面观穿刺针与冠状面正中线的夹角为(83.67±5.99)°,穿刺深度约为(57.45±2.88)mm。结论CT下可通过明显的骨性标志引导穿刺,为临床穿刺提供直观、有价值的解剖信息。
Objective To provide imaging anatomical data used for clinical pterygopalatine ganglion(PPG)puncture via the frontozygomatic angle approach.Methods The pterygopalatine ganglion was localized on the MRI images in 6 patients,and the related bone markers were identified.Simulated punctures of PPG on the CT images were conducted in 142 patients(284 sides),and the puncture-related anatomical data were obtained by imaging measurement.Results The frontozygomatic angle was located at the intersection of the parallel line from(17.01±2.44)mm to the outer edge of orbit and the parallel line from(7.54±3.02)mm to the inferior orbital margin.The angle formed by the puncture needle inserted via frontozygomatic route and the median line of the puncture plane was(68.41±4.19)°.On the coronal plane,the angle formed by the puncture needle and the median line of the coronal plane was(83.67±5.99)°,and the puncture depth was about(57.4±5.88)mm.Conclusion Under CT guidance,the obvious bony markers can provide visual and valuable anatomical information for clinical PPG puncture.
