Tympanomastoid suture and digastric muscle in cadaver and live parotidectomy. Department of Plastic Surgery, R. The location of the nerve was evaluated with respect to the anterior border of the parotid, the tragus and the lateral palpebral commissure. The FTN is at high risk of injury during surgical procedures such as facelift, cutaneous surgery and bicoronal approaches for craniofacial surgical access [ 11 , 12 ]. The upper superior branch of the ZN was found between the main zygomatic and upper masseteric retaining ligaments and located deep 4. As was suggested by Pogrel et al. Cadaver dissection specimen showing the facial nerve , tragal pointer and the posterior belly of digastric.
This article has been cited by other articles in PMC. The rather complicated anatomical course of the VA may be conveniently divided into four consecutive segments Figure The limited interest in studying the course and distribution of the cervical branch may be due to its low rates of injury and the insignificant functional consequence of paralysis of the platysma. Many articles utilised soft tissues as landmarks from which to predict the course of the facial nerve. To find out the most easily identifiable and anatomically consistent landmark for identification of facial nerve during parotid surgery. Unambiguously aligned sequences 14, bp from those 18 species plus 50 percomrphs and two outgroups total 70 species were subjected to partitioned maximum likelihood and Bayesian analyses.
A Case of Wegener’s Granulomatosis Presenting with Unilateral Facial Nerve Palsy
This amounted to an overall rate of 1. The facial nerve is then dissected forward into the parotid gland and the parotid is lifted off the facial nerve. It is quite often necessary to ligate and divide this vein in order to clearly see the nerve. In addition, data from our own anatomic studies are presented. The trigeminal, or fifth cranial nerve, provides the sensory supply to the skin of most of the face except some parts of the skin around the ear and the angle of the jaw.

In current practice, wide ranges of landmarks are used to identify the facial nerve trunk, however, there is much debate in the literature about the safety and reliability of each of these landmarks. Thus further detailed anatomical studies are needed to clarify the homology of this character between the two lineages. Surgical and Radiologic Anatomy Vol.
