The middle meningeal artery is the largest of the three (paired) arteries that supply the meninges, the others being the anterior meningeal artery and the posterior meningeal artery. The anterior branch of the middle meningeal artery runs beneath the pterion. It is vulnerable to injury at this point, where the skull is thin. Rupture of the ...
The auriculotemporal nerve arises from the posterior division of [2]: 497 the mandibular nerve (CN V 3) (which is itself a branch of the trigeminal nerve (CN V)). [3] It arises by two roots [2]: 497 that circle around either side of the middle meningeal artery [1] [2]: 363 before uniting to form a single nerve.
The anterior division of the middle meningeal artery runs underneath the pterion. [4] Consequently, a traumatic blow to the pterion may rupture the middle meningeal artery causing an epidural haematoma. The pterion may also be fractured indirectly by blows to the top or back of the head that place sufficient force on the skull to fracture the ...
The petrosal branch of middle meningeal artery enters the hiatus for greater petrosal nerve, supplies the facial nerve and anastomoses with the stylomastoid branch of the posterior auricular artery. See also
Brazilian President Luiz Inacio Lula da Silva underwent a second procedure on Thursday morning following his emergency brain surgery earlier this week, his doctor said, adding the operation was ...
superiorly, by the greater wing of the sphenoid below the infratemporal crest, and by the under surface of the temporal squama, containing the foramen ovale, which transmits the mandibular branch of the trigeminal nerve, and the foramen spinosum, which transmits the middle meningeal artery.
Epidural hematoma commonly results from a blow to the side (temporal bone) of the head. The pterion region, which overlies the middle meningeal artery, is relatively weak and prone to injury. [10] Only 20 to 30% of epidural hematomas occur outside the region of the temporal bone. [11]
The president underwent a second procedure on Thursday, a middle meningeal artery embolization, aimed at minimizing the risk of additional bleeding in the future. He later had a drain removed from ...
