Step 2.—With chisel, forceps, or Gigli saw divide the bone along the linesmarked in Fig. 113, and remove the bone between the lines of section. Theamount of bone should be as great as possible, to permit wide range of motionsubsequently. Step 3.—From the deep surface of the masseter dissect a flap about i3^inches long, with its pedicle above, consisting of about half the thickness of themuscle. Pass the free end of this flap through the breach in the bone and sutureit to the pterygoid (Fig. 114). Should the flap from the masseter be insufficientfor the purpose, a subsidiary flap may be taken from the p
