Deep temporal nerves

The Deep Temporal Nerves (nn. temporales profundi) are two in number, anterior and posterior. They pass above the upper border of the Pterygoideus externus and enter the deep surface of the Temporalis.

The posterior branch, of small size, is placed at the back of the temporal fossa, and sometimes arises in common with the masseteric nerve.

The anterior branch is frequently given off from the buccinator nerve, and then turns upward over the upper head of the Pterygoideus externus. Frequently a third or intermediate branch is present.
