The depth of the superior labial artery in the upper lip was 5.6 ± 0.13 mm, whereas the depth of the inferior labial artery in the lower lip was 5.2 ± 0.14 mm. Both arteries were more frequently located within the red lip: upper lip (83% vs 18.7%) and lower lip (86.2% vs 13.8%).
How deep are the labial arteries?
Depths of the Labial Arteries The SLA runs deep to the orbicularis oris muscle, lies close to the oral fissure, and lies closer to the oral mucosa than to the skin. The depths of the SLA measured from the skin, oral mucosa, and the lower margin of the upper lip were 4.5 ± 0.8, 2.6 ± 0.3 and 5.6 ± 1.2 mm, respectively.
What happens if you press on the carotid artery?

What happens if filler is injected into an artery?
The most severe potential complication associated with the use of dermal fillers and volume enhancers is arterial/venous occlusion, which leads to ischemia, with subsequent necrosis of the skin and/or vision loss. These events are considered a medical emergency and must be dealt with immediately.
What artery supplies the lower lip?

What does the facial artery Anastomose with?
Ascending palatine artery One branch pierces the superior pharyngeal constrictor, in order the reach the auditory tube and the palatine tonsil. It will then anastomose with the ascending pharyngeal artery as well as the tonsillar branch of the facial artery.
How many branches of external carotid artery are there?
It gives off six branches before it divides into two terminating braches. They are in ascending order: superior thyroid, ascending pharyngeal, lingual, facial, occipital, and posterior auricular. The two terminating branches are the maxillary and superficial temporal arteries.
