Combined Ultrasound and Power-Assisted Liposuction Improves Outcomes in Lipedema: A Retrospective Study

INTRODUCTION: Lipedema is a chronic adipose tissue disorder characterized by disproportionate fat deposition, primarily in the lower extremities, leading to pain, functional impairment, and reduced quality of life. While Power-Assisted Liposuction (PAL) is the standard surgical approach, the integration of Ultrasound-Assisted Liposuction (UAL) with PAL has been proposed to enhance fat removal and improve patient outcomes. OBJECTIVE: To compare the clinical efficacy, postoperative outcomes, and complication rates of PAL alone versus UAL + PAL in patients with Stage II and III lipedema. METHODS: A retrospective cohort study was conducted on 60 female patients diagnosed with lipedema (Stage II and III). 30 patients underwent PAL alone, while 30 received UAL followed by PAL. Primary outcomes included the volume of fat aspirated, circumferential reduction, and postoperative pain, measured at multiple time points over a 12-month follow-up. Secondary outcomes assessed patient satisfaction, time to return to daily activities, and complication rates. RESULTS: The UAL + PAL group demonstrated a significantly higher mean fat extraction volume (5,500 ± 450 mL) compared to the PAL group (4,100 ± 380 mL; p < 0.01). Circumferential reduction was greater in the UAL + PAL group, with an average reduction of 12.5 cm versus 8.2 cm in the PAL group (p < 0.01). Postoperative pain, assessed using a Visual Analog Scale (VAS), was significantly lower in the UAL + PAL group (VAS 4.5 ± 0.7) compared to the PAL group (VAS 6.2 ± 0.8 at 24 hours post-surgery; p < 0.01). Additionally, patients treated with UAL + PAL reported a faster return to daily activities (9.3 ± 1.8 days vs. 12.8 ± 2.1 days; p < 0.01) and higher satisfaction scores (4.8 ± 0.5 vs. 4.2 ± 0.6 on a 5-point Likert scale; p < 0.05). Complication rates were comparable between the two groups, with no major adverse events reported. CONCLUSION: UAL + PAL offers significant advantages over PAL alone in the surgical management of lipedema, providing superior fat removal, reduced postoperative pain, faster recovery, and improved patient satisfaction. These findings support the integration of UAL into standard liposuction protocols for advanced-stage lipedema, emphasizing its efficacy in overcoming the challenges posed by fibrotic adipose tissue.
