The superficial temporal artery is the smaller of 2 terminal branches of the external carotid. It begins behind the mandibular ramus in the substance of the parotid gland and courses superiorly over the posterior aspect of the zygoma. It can be consistently palpated in this region just anterior to the tragus.
What does the superficial temporal artery supply?
The superficial temporal artery (STA) is one of the terminal branches of the external carotid artery (ECA), and it together with other branches of the ECA, supplies the face and scalp .
What does the superficial temporal artery supply blood to?
The temporal superficial artery (TSA) and temporal superficial vein (TSV) are supplying the region of the anterior outer ear and the preauricular, supra-auricular, and temporal skin region. The TSA is the end artery of the external carotid artery and pierces the deep intermuscular space near and in front of the tragus.
What artery directly supplies the superficial temporal artery?
|Superficial temporal artery|
|Branches||Transverse facial artery Middle temporal artery Anterior auricular branch frontal branch parietal branch|
|Vein||superficial temporal vein|
Does the temporal artery supply blood to the neck and arm?
It causes inflammation, swelling, tenderness, and damage to the blood vessels that supply blood to the head, neck, upper body, and arms. It most commonly occurs in the arteries around the temples (temporal arteries). These arteries branch off from the carotid artery in the neck.
Can you feel a superficial temporal artery?
The superficial temporal artery is a blood vessel close to the skin than can be felt in both temples (located on either side of the forehead) and is pictured below.
Why is my temporal artery pulsing?
Feeling a pulse through the temporal artery can signal a malformation in the blood vessel, though this is rare. It can also happen when your heart is moving extra blood with each heartbeat, which can occur with common problems like thyroid disease or anemia.
How deep is the superficial temporal artery?
Superficial temporal artery: 0.8 to 1.5 mm.
How serious is temporal arteritis?
Temporal arteritis is a rare but serious autoimmune disease. Temporal arteritis is a potentially serious condition with many complications if left untreated. Temporal arteritis, also known as giant cell arteritis, is an inflammation of the arteries around the scalp and neck region.
What does the superficial temporal do?
When the superficial temporal artery enters the scalp in the temporal region, it gives off two terminal branches that supply the skin and pericranium of the frontal and parietal regions. Additionally, this artery supplies the parotid gland, temporomandibular joint, and several muscles of the head and face.
Are arteries superficial or deep?
What is inflammation of the temporal artery?
A temporal arteritis is a form of vasculitis (inflammation of the blood vessels). In temporal arteritis, also known as giant cell arteritis or Horton’s arteritis, the temporal arteries (the blood vessels near the temples), which supply blood from the heart to the scalp, are inflamed (swollen) and constricted (narrowed).
How do you palpate the superficial temporal artery?
Palpate the temporal arteries immediately in front of the tragus of the ear and up along the temple. Always check these pulses in an elderly patient with a headache or unilateral visual changes or when polymyalgia rheumatic, giant-cell arteritis, or temporal arteritis is being considered.
Can a 30-year-old get temporal arteritis?
Temporal arteritis in the form of giant cell arteritis (GCA) is common in the elderly but is extremely rare in patients less than 50 years of age.
How long can you live with giant cell arteritis?
|Total number of patients||44|
|Polymyalgia rheumatic diagnosis||9 (20.5%)|
|Vision loss||24 (54.5%)|
