Temporal space

Temporal space is an anatomical term referring to an area of the human head. It is located on the side of the head, above the zygomatic arch and deep to the temporal fascia. This space is filled with the temporal muscle, which is involved in the movement of the jaw.

Anatomy

The temporal space is bounded by several structures. Anteriorly, it is bounded by the posterior aspect of the zygomatic bone. Posteriorly, it is bounded by the temporal bone and the mastoid process. Superiorly, it is bounded by the temporal line of the parietal bone, and inferiorly by the zygomatic arch.

The temporal space contains the temporal muscle, which is one of the muscles involved in mastication. This muscle is responsible for closing the jaw, and is innervated by the mandibular nerve, a branch of the trigeminal nerve.

Clinical significance

Due to its location and contents, the temporal space can be involved in various medical conditions. Infections can spread to the temporal space from the teeth, sinuses, or middle ear. This can lead to abscess formation, which can cause pain, swelling, and difficulty opening the mouth.

Temporal arteritis, also known as giant cell arteritis, is a condition that can affect the temporal artery, which runs through the temporal space. This condition causes inflammation of the artery, which can lead to headache, jaw pain, and potentially vision loss.
