Facial Artery
- Facial artery
- features
- arises in carotid triangle from ECA
- above the tip of greater cornu of hyoid bone
- Then passes through submandibular region
- enters face
- Course
- CERVICAL COURSE
- tortuous course
- allows free movements during swallowing
- runs upwards on superior constrictor of pharynx
- deep to posterior belly of digastric
- with stylohyoid
- to ramus of mandible
- grooves posterior border of submandibular gland
- s bend with two loops
- winds over submandibular gland then to
- over the ramus of mandible
- FACIAL COURSE
- enters face by swindling around base of mandible
- pierces deep cervical fascia
- at the anteroinferior angle of masseter muscle
- palpated here called as “anaesthetist's artery”
- upward and forward to a point 1.25 cm lateral to angle of mouth
- ascends by side of nose
- up to medial angle of eye
- terminates by supplying lacrimal sac
- anastomoses with dorsal nasal branch of ophthalmic artery
- tortuous course
- helps its walls from collapsing
- lies between superficial and deep muscles of face
- Branches
- FACIAL PART
- anterior branches

- upper lip
- anteroinferior part of nasal septum
- lateral nasal
- ala and dorsum of nose
- posterior branches are very small
- CERVICAL PART
- ascending palatine
- goes upward between stylopharyngeus and styloglossus
- tonsillar
