Trunk of the facial nerve
In the proximal part of the ETFN, the labeled zone had a circular shape, and the labeled fibers were sparse Fig. The authors evaluate facial nerve branches in Persian Iranian cadavers, propose classification of the extratemporal nerve, determine topography of the nerve using fixed facial points, and define a new fixed point. On the right side, 3 zygomatic-buccal branches crossed line B-C and were bordered by the quadrangle formed by lines A, B, C, and D in 4 cadavers Coded data were analyzed using a statistical program. Antegrade versus retrograde facial nerve dissection in benign parotid surgery:
Microsurgical anatomy of the facial nerve trunk.
See facial nerve branches mnemonic here. Only 1 zygomatic-buccal branch exited the anterior border of the parotid gland above the parotid duct and then arborized on the right side in 2 cadavers 9. An objective assessment of the advantages of retrograde parotidectomy. The main trunk of the facial nerve was located between the formative tributaries of the retromandibular vein, i. Thank you for updating your details.
Standardization of techniques used in facial nerve section and facial movement evaluation in rats
The length of the trunk of the FN measured from the stylomastoid foramen to the bifurcation point was Surgical anatomy of the rat facial nerve. Distance from the nearest branch to the tragus was The platysmal branch from the marginal mandibular nerve above the mandibular angle innervates the platysma muscle. This variability may help explain the different facial expressions that appear among individual ethnic groups.

Staining results showed that each branch of the facial motor nerve had a topographical orientation in the distal part of the ETFN. Surgical implications of this study are presented with emphasis on HFA surgery. Chronic parasympathetic sectioning decreases regional cerebral blood flow during hemorrhagic hypotension and increases infarct size after middle cerebral artery occlusion in spontaneously hypertensive rats.
