Evaluation of Postoperative Complications in VASER®-assisted Liposuction: A Retrospective Study of 1,486 Cases

Abstract

Aim: Liposuction is a popular plastic surgery procedure with a growing number of cases. Despite advancements, complications remain a significant concern. Modifications like ultrasound-assisted techniques aim to improve safety and efficacy. The aim of this study was to assess the postoperative complications in patients who underwent a vibration amplification of sound energy at resonance (VASER®)-assisted liposuction (VAL) procedure. Materials and Methods: A retrospective study of 1,486 VAL cases was conducted. Patient demographics, surgical procedures, postoperative care, and complications were recorded. Results: Of 1,486 patients, 45 (3.02%) experienced minor complications including loss of sensitivity, tissue stiffness, seroma, hyperpigmentation, and prolonged edema. No major complications or fatalities were observed. There was no significant correlation between fat aspirate volume and complications. Conclusion: VAL demonstrates safety and effectiveness, with a relatively low complication rate. Sensory loss and tissue stiffness were the most common complications. Hyperpigmentation was transient and resolved with postoperative care. Attention to patient selection, meticulous technique application, fluid management, and postoperative care is crucial to minimize complications in VAL procedures. Further studies are required to explore the specific impacts of ultrasound-assisted liposuction on patient outcomes.
