Mastoid foramen

The mastoid foramen is a variably-present foramen as well as being variable in its size, number and position. Most commonly, it is located near the posterior margin of the mastoid process, within the temporo-occipital suture.

It transmits the emissary veins connecting to the sigmoid sinus and a small dural branch of the occipital artery.
