27 lip 2021 · Marginal mandibular nerve is a terminal branch of the extracranial part of the facial nerve and leaves the parotid from its antero-inferior border and travels beneath the platysma muscle and deep cervical neck fascia, after which its course becomes superficial to the facial vessels.
16 gru 2020 · The marginal mandibular branch (MMBr) of the facial nerve is the least likely to recover from injury due to infrequent anastomosis with other branches. The MMBr has been described as coursing superior to the inferior border of the mandible.
The high number of marginal mandibular nerve (MMN) anatomical variants have a well-known clinical significance due to the risk of nerve injury in several surgical procedures. The aim of this study was to find and systematize the available anatomical data concerning this nerve.
The marginal mandibular branch of the facial nerve arises from the facial nerve (CN VII) in the parotid gland at the parotid plexus. It passes anterior-ward deep to the platysma and depressor anguli oris muscles.
The marginal mandibular branch of the facial nerve is a motor nerve that innervates muscles of facial expression in the lower face. It sends branchial motor efferents. The muscles innervated by the marginal mandibular branch include the orbicularis oris, depressor anguli oris, depressor labii inferioris, and mentalis muscles. Complete Anatomy.
29 mar 2016 · The marginal mandibular branch (Mbr) of the facial nerve is vulnerable to damage during rhytidoplasty, surgical reduction of the mandibular angle, parotidectomy, and excision of the submandibular gland.
The marginal mandibular branch (Mbr) of the facial nerve is vulnerable to damage during rhytidoplasty, surgical reduction of the mandibular angle, parotidectomy, and excision of the submandibular gland. The authors sought to map the Mbr and determine the relationship between the number of Mbr offshoots and the course of the Mbr.
