The mastoid foramen is a large hole in the posterior border of the temporal bone. It transmits a Mastoid emissary vein to the sigmoid sinus and a small branch of the occipital artery, the posterior meningeal artery to the dura mater.

Variations

The position and size of this foramen are very variable; it is not always present; sometimes it is situated in the occipital bone, or in the suture between the temporal and the occipital.

It transmits (1) an emissary vein connecting the sigmoid sinus with the posterior auricular vein and (2) a meningeal branch of the occipital artery

We investigated whether mastoid pneumatization plays a role in the protection of vital structures in the temporal bone during direct lateral trauma.

Impact of removing mastoid process for advanced parotid cancer on facial nerve identification, preservation and reconstruction.

Even though facial nerve was preserved, facial nerve stretching during surgery has significantly serious effect on postoperative facial palsy.
