摘　　要：目的　探讨面神经阻滞入路相关结构的解剖关系 ,为面神经阻滞的进针入路和预防并发症的发生提供解剖学依据。方法　成年男性尸体 2 8具 (5 6侧 ) ,模拟面神经阻滞穿刺 ,用游标卡尺进行测量。结果　面神经阻滞穿刺点的位置为外耳道软骨下缘、乳突前缘和下颌支后缘的交汇处 ,垂直于正中矢状面进针 ,左侧深度为 19 91± 0 0 9mm ,右侧为 19 82± 0 10mm。结论　本研究确定了面神经阻滞准确的穿刺点、穿刺角度及深度 ,有利于麻醉药发挥作用以提高疗效。Objective To study the applied anatomy of the related structures of approach for blocking the facial nerve to provide anatomical bases for accurate puncturing point and preventing complications. Methods 28 adult male cadavers (56 sides) were used to mimic the puncture and measure the correlative structures with anatomical method. Results The blocking point was located at the convergent point of the inferior edge of cartilage of the external acoustic canal and the anterior fringe of mastoid processes and the posterior fringe of mandible ramus, and the needle must be thrusted vertical to the median sagittal plane. On the left side the puncturing depth was 19.91±0.09 mm, on the right side the puncturing depth was 19.28±0.10 mm. Conclusion The experimental study could provide accurate puncturing point?angle and depth for blocking the facial nerve and bring the anethetic medicine into full play.
