Lateral SMASectomy Facelift

Abstract There are several advantages of lateral SMASectomy in comparison with traditional elevation. First, because the procedure does not require traditional SMAS flap elevation, there is less concern about tearing of the superficial fascia. Second, the potential for facial nerve injury is lower because most of the deep dissection is over the parotid gland. If the SMASectomy is performed anterior to the parotid, the deep fascia will similarly provide protection for the facial nerve branches as long as the resection of the superficial fascia is done precisely and the deep fascia is not violated. Third, because SMAS flaps have not been elevated, they tend to hold suture fixation more strongly, and the potential for postoperative dehiscence and relapse of contour is decreased.
