Long-term Analysis of Lip Augmentation With Superficial Musculoaponeurotic System (SMAS) Tissue Transfer Following Biplanar Extended SMAS Rhytidectomy.

Importance: To our knowledge, long-term, objective results of lip augmentation using superficial musculoaponeurotic system (SMAS) tissue transfer beyond 1 year have not been previously described.

Objective: To evaluate the efficacy, longevity, and safety of lip augmentation using SMAS tissue transfer.

Design, Setting, And Participants: A retrospective single-blind cohort study was designed to evaluate all patients who underwent surgical lip augmentation using SMAS following rhytidectomy between January 1, 2000, and November, 16, 2015, at a private facial plastic surgery practice in Birmingham, Alabama.
