Percutaneous identification of the temporal branch of the facial nerve.

A technique is presented for percutaneous localization of the temporal branches of the facial nerve based on their relation to the fixed bony landmarks of the lateral orbital wall and the superior border of the zygomatic arch. Anthropometric measurements of the lateral orbital walltragion distance in cadavers and live volunteers were made to correlate this with the position of the temporal branch as it crosses the superior border of the zygomatic arch.
