Stylomastoid artery

Artery: Stylomastoid artery
The arteries of the face and scalp.
Latin	arteria stylomastoidea
Gray's	subject #144 557
Supplies	tympanic cavity, tympanic antrum, mastoid cells, semicircular canals
Source	posterior auricular artery

The stylomastoid artery enters the stylomastoid foramen and supplies the tympanic cavity, the tympanic antrum and mastoid cells, and the semicircular canals.

In the young subject a branch from this vessel forms, with the anterior tympanic artery from the internal maxillary, a vascular circle, which surrounds the tympanic membrane, and from which delicate vessels ramify on that membrane.

It anastomoses with the superficial petrosal branch of the middle meningeal artery by a twig which enters the hiatus canalis facialis.
