Abstract 7. Prospective, Double-Blind Evaluation of Umbilical Reconstruction of Techniques Using Conventional and Crowdsourcing Methods

M oday, M arch 7, 2017 METHODS: From 2005–2016, 1,000 consecutive patients underwent rhytidectomy by the senior author (LPB). In addition to implementing cannula lipodissection, the senior author avoids routine anterior platysmaplasty as it was observed to limit jowl excursion of the lower face. In an attempt to validate the abovementioned approach (developed from clinical observation), a cadaveric study was performed on five fresh tissue cadavers. Post-auricular skin excursion was measured following lipodissection (cannula only) and then measured again after traditional wide undermining. Next, SMAS flap and jowl excursion were measured with and without anterior platysmaplasty. A force gauge was utilized to ensure that equivalent force was applied during all comparisons of skin and SMAS excursion.
