The parietal branch of the superficial temporal artery (posterior temporal) is a small artery in the head. It is larger than the frontal branch and curves upward and backward on the side of the head, lying superficial to the temporal fascia ; it joins with its fellow of the opposite side, and with the posterior auricular and occipital arteries .
The temporal area may be tender. [21] Decreased pulses may be found throughout the body [21] Evidence of ischemia may be noted on fundal exam. [21] Bruits may be heard over the subclavian and axillary arteries [21] Intermediate magnification micrograph showing giant cell arteritis in a temporal artery biopsy. The arterial lumen is seen on the left.
The anterior auricular branches of the superficial temporal artery are distributed to the anterior portion of the auricula, the lobule, and part of the external meatus, anastomosing with the posterior auricular. They supply the external acoustic meatus and the visible part of the ear. Arterial vascular pattern of the auricle:
In cases where symptoms suspicious of giant cell arteritis (GCA) are present, but a temporal artery biopsy reveals fibrinoid necrosis in small vessels branching from the temporal artery, and the absence of the typical GCA histological features, this discrepancy may suggest an alternative diagnosis, as the occurrence of fibrinoid necrosis in GCA ...
Temporal artery may refer to: Deep temporal arteries, two in number, anterior and posterior, ascend between the temporalis and the pericranium; Middle temporal artery, arises immediately above the zygomatic arch; Superficial temporal artery, a major artery of the head
superficial temporal branches of auriculotemporal nerve - "rami temporales superficiales nervi auriculotemporalis" Arteries Temporal branches of the middle meningeal artery; Temporal branches of the middle cerebral artery; posterior temporal branches of lateral occipital artery - "rami temporales posteriores arteriae occipitalis lateralis"
temporal arteritis In radiology , the halo sign is a finding of a dark halo around the arterial lumen on ultrasound that suggests the diagnosis of temporal arteritis . [ 1 ] The standard diagnostic test for temporal arteritis is biopsy ; however, ultrasound and MRI show promise for replacing it.
A temporal artery biopsy (TAB) can be performed to differentiate between the two disease states. [13] As the disease progresses, the arteriosclerosis results in the obstruction of normal blood flow, and potentially the formation of blood clots.
