Comparison of Deep SMAS Lift and MACS in Facelift: A Meta-Analysis.

Background and

Objectives

According to the PRISMA guidelines, this meta-analysis evaluates the outcomes of deep Superficial Musculoaponeurotic System (SMAS) lift versus Minimal Access Cranial Suspension (MACS) lift techniques in facelift surgery. Materials and

Methods

We reviewed literature that included 20 studies involving a total of 7716 patients, of which four studies met our inclusion criteria, focusing on 286 patients (MACS n: 186 and SMAS n: 100). Our analysis assessed surgical duration, complications, pain levels, and aesthetic results.

Results

Although both techniques yielded comparable aesthetic outcomes and postoperative complications, the MACS lift demonstrated a significantly shorter surgical duration (SMD = 2.05; 95% CI [1.61-2.48]; p < 0.00001, I2 = 0%) which has high impact on patient recovery, risk of complications and cost-effectiveness.

Conclusions

The findings underscore the need for further research into varying techniques to solidify their efficacy and safety profiles.
