The document discusses anatomy relevant to forehead and brow rejuvenation procedures. It notes that the deep temporal fascia attaches along the temporal ridge and continues medially as the periosteum covering the frontal bone, while the superficial temporal fascia continues medially as the galea aponeurotica surrounding the frontalis muscle. The inferior temporal septum is a useful landmark during endoscopic dissection as it separates the upper safe zone with no vital structures from the lower zone through which facial nerve branches and the medial zygomatic temporal vein pass near the lateral orbital rim.

periosteum that covers the frontal bone. Similarly, the superficial temporal fascia (also known as the temporal parietal fascia)
continues medially as the galea aponeurotica that encompasses the frontalis muscle.
7. The inferior temporal septum is a useful landmark during endoscopic dissection from above, because it separates the safe uppe
r zone
containing no vital structures from the lower zone where facial nerve branches travel in the cavitys roof. The medial zygomatic temporal vein
(sentinel vein) is also present in this lower zone, adjacent to the lateral orbital rim. The temporal branches pass immediately superior to this
vein
