Kocliers Operation.—An incision beginning just behind the frontalprocess of the malar bone is carried obliquely downward and backward tothe posterior extremity of the zygomatic arch^ thence upward and backwardin front of the ear at nearly right angle to the first part of the incision(Fig. 314), dividing fibers of the orbicularis, the superficial and temporalfasciae at the first, and all tissues down to the bone at the second part of theincision. Draw the borders of the wound apart; expose the malar bonebehind the frontal process and divide it vertically with a chisel; divide thezygoma posteriorly close to its anterior root, and draw the fragment down.
