Importance The evaluation of the effects of midline platysmaplasty concomitant with rhytidectomy. OBJECTIVE To determine whether midline platysmaplasty limits the degree of lift during deep-plane face-lift. DESIGN, SETTING, AND PARTICIPANTS Deep-plane rhytidectomywas performed on 10 cadaveric hemifaces. The redundant skin for excision after performing the face-lift was measured with and without midline platymaplasty. EXPOSURES Deep-plane rhytidectomy. MAIN OUTCOMES AND MEASURES The redundant skinwas measured preauricularly in the vertical and horizontal dimension, and postauricularly after deep-plane face-lift and after adding a midline platysmaplasty. RESULTS Concomitant midline platysmaplasty significantly reduced the amount of lift during concomitant deep-plane rhytidectomy preauricularly in the vertical dimension by 40.5% (from 37.0mmexcess skin redraped to 22.0 mm) and postauricularly by 23.9%(from 40.6 mmexcess skin redraped to 30.9 mm) (P <.001 and P <.001, respectively). The 19.7% reduction in the horizontal skin redraping after midline platysmaplasty (from 14.7mmexcess skin redraped to 11.8 mm) did not reach statistical significance (P =.15) CONCLUSIONS AND RELEVANCE Concomitant midline corset platysmaplasty significantly limits the ability to lift the neck as well as the jawline and midface during rhytidectomy.
