【摘要】 目的:探讨上颌神经阻滞的方法,预防其并发症的发生。方法:观测120例成人颅骨翼腭窝等结构数据,观测30例成人尸头上颌神经的毗邻结构。结果:上颌神经阻滞进针深度:(1)侧入法:颧弓中点下缘至翼腭窝底的距离,男性左侧为47.15±1.07 mm,右侧为46.41±1.01 mm。女性左侧为45.43±1.06 mm,右侧为44.69±0.99 mm。(2)侧前入法:下颌骨冠突与颧骨下缘交点至翼腭窝底的距离:男性左侧为52.35±0.75 mm,右侧为52.78±0.84 mm。女性左侧为49.71±0.79 mm,右侧为49.94±0.82 mm。结论:本研究为上颌神经阻滞入路进针深度和预防发生并发症提供了解剖学参考依据。更多还原

【Abstract】 Objective:To study the approaches to blocking maxillary nerve for prevention of complication.Method: Skull pterygopalatine fossa in 120 adult cases and adjoining structures of maxillary nerve in 30 adult necropsies were measured.Results:The depth of needle in maxillary nerve block:(1)Lateral approach method:The distance between the lower edge of the center of zygoma and the bottom of the pterygopalatine fossa,the male were 47.15±1.07 mm and 46.41±1.01 mm for the left and right side respectively,the female were 45.53±1.06 mm and 44.69±0.99 mm for the left and right side respectively.(2)Lateral and front approach method:The distance from the joint of coronoid process of mandible and the lower edge of zygoma to the bottom of the pterygopalatine fossa,the male were 52.35±0.75mm and 52.78±0.84mm for the left and right side respectively,and the female were 49.71±0.79 mm and 49.94±0.82 mm for the left and right side respectively.Conclusion:This study provides reference data for the depth of needle insertion and anatomical basis for the prevention of complications caused by the blocking of the maxillary nerve.更多还原
