Progressive Tension Sutures in the Prevention of Postabdominoplasty Seroma: A Prospective, Randomized, Double-Blind Clinical Trial

Abstract

Progressive tension sutures increase surgical time, reduce drain outputs, and have the same clinical and ultrasound seroma frequency as the use of drains alone. The combination of both methods simultaneously does not add any advantages. However, complications and interventions increase if at least one of them is not used. The mechanism of action of progressive tension sutures could be the compartmentalization of the fluid collection under the flap facilitating absorption.
