The Effect of Midline Corset Platysmaplasty on Degree of Face-lift Flap Elevation During Concomitant Deep-Plane Face-lift: A Cadaveric Study.

[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.
