To determine whether superficial musculoaponeurotic system (SMAS) graft implantation can improve the appearance of the nasolabial fold.
Single-blinded cohort study in a private facial plastic surgery practice.
Treatment and control patients were selected from those presenting for aesthetic surgery.
All patients underwent rhytidectomy with SMAS imbrication by a single surgeon.
In addition, treatment patients underwent subcutaneous implantation of excised SMAS strips to the nasolabial fold.
Treatment and control patients were matched for any other simultaneous procedures known to affect appearance of the nasolabial folds.
Preoperative and postoperative photographs were graded by 3 blinded observers using the Wrinkle Severity Rating Scale to evaluate the nasolabial fold.
Postoperative photographs were evaluated approximately 3 months and again 1 year after the procedure.
Compared with controls, there was a significant difference in the nasolabial folds of patients undergoing SMAS implantation at the 3-month postoperative evaluation (P = .03; chi(2) = 4.696). This benefit was lost when the results were evaluated 1 year after the procedure (P = .88; chi(2) = 0.0212).
Superficial musculoaponeurotic system implantation to the nasolabial folds offers modest temporary improvement to this area in patients undergoing rhytidectomy with SMAS imbrication.
