剪切波弹性成像评估吸脂联合腹壁整形术后软组织弹性变化的临床研究OA

Objective The changes in the elasticity of the abdominal skin,subcutaneous tissues and muscles after lipoabdominoplasty are still unknown.The aim of this study was to provide an objective assessment of tissue elasticity after lipoabdominoplasty using ultrasound elastography.Methods A total of 40 female patients who underwent lipoabdominoplasty from Oct 2023 to Mar 2025 were included in this retrospective study.The elastography values of the skin,subcutaneous tissues and abdominal muscles were obtained with the ultrasound shear wave elasticity imaging system pre-operation(Pre)and 6 months post-operation(Post)at two different points(P1 is the point directly above the umbilicus;P2 is the midpoint of the line connecting the anterior axillary line and the anterior superior iliac spine).Results Six months after the surgery,the postoperative elastic values of the three layers of soft tissues(skin,subcutaneous fat,and muscle)at the P1 and P2 sites of the patients were significantly higher than those before the surgery(P＜0.05).The increase in skin elasticity was the greatest,while the increase in subcutaneous fat elasticity was the smallest,and the increase in muscle elasticity was between those of the skin and subcutaneous fat.Conclusion Significant changes in the elasticity of the abdominal skin,subcutaneous tissues and muscles were observed after lipoabdominoplasty.Ultrasound elastographic assessment was objective and feasible for evaluating the effect of lipoabdominoplasty on abdominal soft tissue.
