Stephanion

Stephanion is the point on the skull where the temporal line of the parietal bone and the supramastoid crest of the temporal bone meet. It is located superior to the external acoustic meatus and posterior to the zygomatic process of the frontal bone.

Anatomy

The Stephanion is a craniometric point in the human skull. It is the point at which the upper temporal line (the edge of the temporal fossa) and the supramastoid crest (the ridge above the mastoid process) intersect. This point is located above the external acoustic meatus, or the opening of the ear, and behind the zygomatic process of the frontal bone, the part of the skull that forms the cheekbone.

Clinical significance

The location of the Stephanion can be used in surgical procedures involving the temporal bone or the parietal bone. It can also be used as a landmark in radiographic studies of the skull.
