Background: This study aimed to compare the average amounts of facial skin and muscle lifting in two different face-lift
methods, superficial musculoaponeurotic system (SMAS) plication and minimal access cranial suspension (MACS), to
evaluate the effectiveness of each method in facial excursion.
Methods: Thirty-six face-lift surgeries were performed on nine cadavers between October and December 2010. Both SMAS
and MACS surgeries were done on each side of the cadaver faces. The average amounts of skin and muscle lifting up and out
in three defined anatomical landmarks were compared between the two methods, SMAS plication and MACS lift procedure.
Results: Nine fresh cadavers with the mean age of 53�±6.7 years entered the study. Seven (77.8%) were males and two (22.2%)
were females. The average amounts of lifting of the anatomical landmarks up and out were significantly greater in the SMAS
plication method compared to the MACS lift procedure (P values<0.05), whereas facial symmetry was not significantly
different between the two methods.
Conclusion: The overall amounts of facial skin and muscle lifting by the SMAS plication method were greater than the MACS
lift procedure. However, it does not justify ignoring the benefits of the MACS lift procedure in terms of less invasiveness and
quicker recovery.
