Vertical platysma myocutaneous flap that sacrifices the facial artery
The few reported cases more often involve the facial artery
, likely, because it's course adjacent to the mandible makes it vulnerable to trauma.
2003) indicated that in 71% of a sample of 91 corpses the labial arteries originated from independent locations from the facial artery
with an average distance of 30.
Paulley and Hughes(18) favor facial artery
biopsy if needed to confirm the diagnosis.
The vascularity of the Nasolabial flap is based on the angular branch of the facial artery
, the transverse facial artery
and the infraorbital artery.
8 Other major advantages of this flap are its versatility, easy to raise flap, a quick single stage procedure; and, its viability is not affected by facial artery
ligation when synchronous neck dissection is performed in SCC patients.
Color Doppler sonography of the facial artery
in the anterior face.
All but 2 patients (1 who required the ligation of a facial artery
false aneurysm and the other with persistent facial nerve palsy) were satisfied with the eventual outcome of surgery.
This study on the anatomical relation of marginal mandibular nerve with respect to the lower border of mandible and facial artery
will benefit maxillofacial and plastic surgeons in its safe iden- tification hence preserving the functional integrity of this significant branch of facial nerve.
Anatomic evaluation of the facial artery
and vein using color Doppler ultrasonography.
The facial artery
and vein are usually ligated and transected during the procedure, and either suction or nonsuction wound drainage is generally instituted.
and vein were used for vascular anastomosis.
