temporal line

The superior or the inferior temporal line. The superior temporal line is an arching ridge along the lateral surface of the skull; it begins as a continuation of the upper posterior border of the zygomatic bone and continues as a broad arch along the frontal and parietal bones, above and roughly parallel to the upper edge of the temporal bone. The inferior temporal line begins with the superior temporal line and separates from its lower edge to form a parallel but tighter and lower arch. The inferior temporal line marks the origin of the temporalis muscle; the superior temporal line marks the attachment of the muscle's fascia.

The thickness at the temporal line (LTL and RLT) increased with age, whereas the thickness near the bregma (RB and LB) decreased.
The bone hole should be posterior to the temporal line, and the location should not be too low to avoid milling through the orbital wall.
(4) Therefore, in order to identify and safely approach the vital structures in the skull base during surgeries, many accessible anatomical surface landmarks like the mastoid tip, the digastric muscle, the spine of Henle, the cribriform area, the temporal line, the external auditory canal and the root of the zygomae (2) are used to relate and access the underlying anatomical structures.
The temporal line was continuous of the temporal crest and ran over the parietal bone.
