Applied anatomy of marginal mandibular branch of facial nerve

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.
