The temporal fascia is a strong fibrous investment.
Structure Superiorly, it is a single layer, attached to the entire extent of the
superior temporal line. Inferiorly, where it is fixed to the
zygomatic arch, it consists of two layers, one of which is inserted into the lateral, and the other into the medial border of the arch.
Contents A small quantity of fat, the orbital branch of the
superficial temporal artery, and a filament from the
zygomatic branch of the
maxillary nerve, are contained between the two layers created by the inferior split of the fascia.
Attachments The superficial fibers of the
temporalis muscle attach onto the deep surface of the temporal fascia.
Relations Superficial to the temporal fascia are the
auricularis anterior muscle and
superior auricular muscle, the
galea aponeurotica and (part of) the
orbicularis oculi muscle. The superficial temporal vessels and the
auriculotemporal nerve cross it inferoposteriorly. The
parotid fascia proceeds to the temporal fascia. == References ==
