Zygomatic arch cracking for cosmetic improvement: technical note.

We describe a simple cracking method for removing the zygomatic arch. The drilling line of the zygomatic arch is partially drilled from the back, and the surface is left undrilled. The zygomatic arch is cracked during its removal in order to secure its position for later fixation. Dead bone spaces can be avoided by this method and the zygomatic arch can be replaced in its original position. By adding this procedure to the standard technique, this cracking method is a simple, safe and useful way to achieve better cosmetic results.
