Incision of the superficial temporal fascia for exposure of the zygomatic arch

The superficial layer of the temporalis fascia is progressively dissected in an anterior direction and then turned laterally to reach the periosteum along the superior surface of the zygomatic arch.
The periosteum is incised at the superior aspect and reflected over the arch, the posterior border of the body of the zygoma and the lateral orbital rim.
The subperiosteal temporal dissection is connected with the subperiosteal dissection over the lower forehead.
The subperiosteal temporal dissection can also be initiated from the lateral forehead and advancing over the zygomaticofrontal suture.
