We define and introduce the mandibular defining line, a new anatomic metric in evaluating the mandibular contour. We define the area of the posterior lower face overlying the gonion and mandibular angle as the gonial area. Using 3-dimensional photography, we quantify contour changes along the mandibular border and volume change along the gonial area.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>Eighty-nine patients (178 hemifaces) were analyzed. The mean gonial area volume gained was 3.5 cc. Average follow-up was 19 months. There was a statistically significant change in the mean mandibular defining line from 7.1 cm preoperatively to 9.8 cm postoperatively. This represents a lengthening of the visual perspective of the mandibular contour of 2.7 cm.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>Composite, rotational flap modification of extended deep-plane rhytidectomy provides significant long-term augmentation of volume to the posterior mandibular region and lengthens the visual perspective of the inferior mandibular contour, creating a more youthful jawline. In selected cases, this may obviate the need for other volumization procedures used to improve jawline contour, such as autologous fat grafting.<\/jats:p>\n                  <\/jats:sec>\n
