The square chin and the pointed chin: Another refinement in facial aesthetics.

The authors present a simple surgical procedure for changing a pointed chin into a square one, through the resectioning of a horizontal bone fragment of the free edge of the mentum. An amount of soft tissue of this region can be resected during surgery as a secondary reshaping maneuver. A third technical detail can be added to improve the final result, using a small bone resection wedge in the middle of the mentum edge. A lazy groove on the new square chin line is obtained. A comparative, preoperative and postoperative study of the face contour is presented.
