The deep temporal nerves are typically two nerves (one anterior and one posterior) which arise from the mandibular nerve (CN V₃) and provide motor innervation to the temporalis muscle.

Structure

Origin

They usually arise from (the anterior division of) the mandibular nerve (CN V₃).[1][2]

Course

They pass superior to the superior border of the lateral pterygoid muscle.[1] They ascend to the temporal fossa and enter the deep surface of the temporalis muscle.[2]

Distribution

The deep temporal nerves provide motor innervation to the temporalis muscle. The deep temporal nerves also have articular branches which provide a minor contribution to the innervation of the temporomandibular joint.[3]

Variation

Number

There are usually two deep temporal nerves - the anterior deep temporal nerve and posterior deep temporal nerve. Occasionally, a third one is present - the middle deep temporal nerve.[2]

Origin

The anterior one may arise from the buccal nerve, and the posterior one may arise from the masseteric nerve.[2]
