Increasing Superficial Musculoaponeurotic System Durability and Retention in Facelift Surgery.
Article in Aesthetic surgery journal. Open forum, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundFacelift surgery remains the gold standard for facial rejuvenation, yet limitations such as suture pull-through failure, superficial musculoaponeurotic system (SMAS) laxity, and the need for secondary procedures persist. Although novel facelift techniques have emerged, none have effectively addressed the inherent biomechanical challenges. Photochemical tissue passivation (PTP) is a promising method to enhance tissue durability and improve facelift longevity by modifying the biomechanical properties of the SMAS itself.
objectivesIn this study, the authors investigated whether PTP enhances the biomechanical properties of SMAS, strengthens tissue integrity, and improves suture retention strength, thereby reducing the likelihood of recurrent laxity and the need for revision facelifts.
methodsSMAS tissue was harvested from facelift patients (
resultsPTP-treated human SMAS demonstrated a 229% increase in suture pull-through resistance (
conclusionsPTP significantly enhances the biomechanical strength of the SMAS, reduces postoperative laxity in a rat model, and improves suture retention capacity in human SMAS tissue. These effects indicate that PTP has the potential to substantially increase the durability of facelifts and reduce revision rates, positioning it as a valuable adjunct technique in facial rejuvenation surgery. Additional clinical studies are needed to confirm these findings.
