โฆ Synopsis
In order to avoid injury to the marginal mandibular branch of the facial nerve during surgery in the face and neck, a simple method for locating this branch was devised. The anatomical relations between the marginal mandibular nerve and both the facial artery and vein were analyzed in 19 dissection preparations. The following distances were considered: 1) the angle of the mandible to the intersection point nerve-vein; 2 ) mandibular angle to the facial artery; 3) inferior mandibular margin to the intersection point nerve-vein; 4) facial artery to the intersection point projection nerve-vein; 5) facial artery to the intersection point projection nerve-vein on the inferior mandibular margin; and 6) facial vein to the facial artery. These data are useful for an easier localization of the marginal mandibular nerve in the submandibular region. All reference points employed are easily detected in a living subject.
