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:
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.
In the neck, the artery issues branches to the digastric muscle, stylohyoid muscle, sternocleidomastoid muscle, and the parotid gland. [1]In the neck, the posterior auricular artery issues the stylomastoid artery which enters the stylomastoid foramen to provide arterial supply to the facial nerve (CN VII), tympanic cavity, mastoid air cells of the mastoid antrum, and the semicircular canals.
The auricular branch of posterior auricular artery is a small artery in the head. It branches off the posterior auricular artery and ascends behind the ear, beneath the posterior auricular muscle, and is distributed to the back of the auricula, upon which it ramifies minutely, some branches curving around the margin of the cartilage, others perforating it, to supply the anterior surface.
The anterior tympanic artery (glaserian artery [citation needed]) is a branch of (the mandibular part of) the maxillary artery. [1] It passes through the petrotympanic fissure [ 1 ] [ 2 ] to entre the middle ear where it contributes to the formation of the circular anastomosis around the tympanic membrane . [ 2 ]
The brachiocephalic artery or trunk is the first and largest artery that branches to form the right common carotid artery and the right subclavian artery. This artery provides blood to the right upper chest, right arm, neck, and head, through a branch called right vertebral artery .
