Clinical investigation on skin changes after face lift based on extended subcutaneous and sub-SMAS undermining and multiple accurate plication of SMAS system / 中华整形外科杂志

ABSTRACT

Objective@#To explore the skin condition and histological changes after face lift based on extended subcutaneous and sub-SMAS undermining and multiple accurate plication of SMAS system.@*Methods@#Eighteen patients that underwent face lift were enrolled according to the inclusion and exclusion criterion. Objective, subjective and histological evaluations were performed to study the skin changes.@*Results@#Nine patients completed the study and skin condition improved significantly after face lift from the objective and subjective results. Histological evaluation revealed that epidermal thickness increased along with dermal collagen content. Collagen and elastic fibers were more condensed after surgery than before, suggesting the dermal regeneration after face lift.@*Conclusions@#Skin regeneration after face lift can help maintain the postoperative result. Extensive subcutaneous dissection along with removal of lax skin as much as possible are the key points of face lift.
