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 rhytidectomy was 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 skin was 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 37.0 mm excess skin redraped to 22.0 mm) and postauricularly by 23.9% (from 40.6 mm excess 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 14.7 mm excess 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.
LEVEL OF EVIDENCE: NA.
