The fascia is attached superiorly at the superior temporal line; inferiorly, it splits into two layers at the superior border of the zygomatic arch - the superficial layer then attaches to the lateral aspect of the superior border of the arch, and the deep layer to its medial aspect.[1]: 357
Inferiorly, where it is fixed to the zygomatic arch, it consists of two layers, one of which is inserted into the lateral, and the other into the medial border of the arch.[citation needed]
