Objective: To compare the intraoperative outcomes of superficial musculoaponeurotic system plication, imbrication, and deep-plane rhytidectomy techniques.
Methods: Thirty-two patients undergoing primary deep-plane rhytidectomy participated. Each hemiface in all patients was submitted sequentially to 3 progressively more extensive lifts, while other variables were standardized. Four major outcome measures were studied, including the extent of skin redundancy and the repositioning of soft tissues along the malar, mandibular, and cervical vectors of lift. The amount of skin excess was measured without tension from the free edge to a point over the intertragal incisure, along a plane overlying the jawline. Using a soft tissue caliper, repositioning was examined by measurement of preintervention and immediate postintervention distances from dependent points to fixed anthropometric reference points.
Results: The mean skin excesses were 10.4, 12.8, and 19.4 mm for the plication, imbrication, and deep-plane lifts, respectively. The greatest absolute soft tissue repositioning was noted along the jawline, with the least in the midface. Analysis revealed significant differences from baseline and between lift types for each of the studied techniques in each of the variables tested.
Conclusion: These data support the use of the deep-plane rhytidectomy technique to achieve a superior intraoperative lift relative to comparator techniques.
