Tideman et al described the anatomical characteristics, blood supply, surgical technique in the clinical results of 12 cases of reconstructions of surgical defects in the oral cavity.9 Buccal fat pad is an easily accessible tissue with reasonable mobility and adequate blood supply from facial artery
,maxillary artery and superficial temporal artery.
Vertical platysma myocutaneous flap that sacrifices the facial artery
musculomucosal flap (FAMM) is a pedicle flap that could be proximally or distally raised based on 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.
These structures include the parotid gland, masticator space, minor and ectopic salivary glands, lymph nodes, muscle, sinuses, facial artery
and vein, and other neurovascular structures.
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.
Currently the proven reliability of the nasolabial flap, with its predictable functional and acceptable aesthetic results, makes it the ideal local flap for recon- struction of oral defects that are too large for primary closure and too small for conventional musculo-cu- taneous and micro vascular free flaps.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.9,10
Niranjan (1988) described a great quantity of variations in the distance, the manner of completion of the facial artery
, and the form in which the labial arteries originate.
Complications following parotidectomy for LEL included facial nerve palsy (N = 3), seroma formation (N = 5) and facial artery
false aneurysm (N = 1).
But in majority of cases in lingual thyroid is supplied by branches of lingual artery or facial artery
which can be ligated or coagulated.
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.
