【摘要】 目的为临床腮腺区良性肿瘤切除术时定位和处理面神经其分支提供解剖学资料。方法对16侧成人面侧区进行局部解剖,着重观察面神经下颌缘支下的行程及其与下颌后静脉前支、面静脉的相互关系。结果面神经下颌缘支位于下颌角与颏孔连线、下颌后静脉前支、面静脉下端所围成的下颌缘支三角内,其行程以下颌角处为起点,下颌体下缘为中线,上、下方各14.5 mm的区域,下颌缘支三角的∠AOB平分线至的对边中点的线段作为面神经下颌缘支的投影线,下颌缘支行于此投影线上的占88%。结论临床腮腺区良性肿瘤切除术,面神经探查分离时,可在下颌缘支三角内先暴露面神经下颌缘支,逆行分离探查面神经主干及其分支,下颌缘支的投影线可作为寻找面神经下颌缘支的重要标志。更多还原

【Abstract】 Objective To provide anatomical data for clinical parotid benign tumor resection, location, treatment of facial nerve and branches. Methods 16 sides of adult side area of the relationship were performed on part anatomy. We focus on watching the relationship between stroke marginal mandibular branch of the facial nerve and the vein and posterior mandibular anterior branch, facial vein. Results The marginal mandibular branch river the marginal mandibular branch of the facial nerve in the mandibular angle and mental foramen, anterior branch of the retromandibular vein connection, facial vein was formed, the stroke of mandibular angle as a starting point, the lower edge of mandibular body midline, below each 14.5 mm region, marginal mandibular branch river of ∠ AOB. On the side of the midpoint of the line to line as the marginal mandibular branch of the facial nerve projection line, marginal mandibular branch in this projection line 88%. Conclusion The clinical parotid benign tumor resection, facial nerve exploration and separation, the marginal mandibular branch river within the first exposure marginal mandibular branch, exploration of retrograde dissection of facial nerve trunk and its branches, marginal mandibular branch of the projection line can be used as an important symbol for marginal mandibular branch of the facial nerve.更多还原
