Mastoid process
Processus mastoideus
- Latin synonym: Processus mastoides
Definition
The mastoid process is a significant cone-shaped projection from the bottom of the skull, situated just behind the ear opening–the external acoustic meatus–and positioned posterolateral to the styloid process. It points downward and forward. The mastoid process provides a point of attachment for several muscles and has a groove on its inner side known as the mastoid notch, which anchors the posterior belly of the digastric muscle.
