Direct Sub-Scarpal Lipectomy Combined With Liposuction in Abdominoplasty: An Analysis of Safety & Efficacy in 200 Consecutive Patients

Abstract

Background: Abdominoplasty procedures continue to evolve as combining techniques such as suction-assisted lipectomy or direct sub-scarpal lipectomy have proven to be powerful adjuncts to achieve optimal aesthetic results. However, there is apprehension in combining techniques simultaneously given the potential to affect the vascularity of the abdominoplasty flap.

Objectives: To assess the safety and efficacy of simultaneous direct sub-scarpal lipectomy combined with liposuction in abdominoplasty patients.

Methods: A 4-year retrospective review of consecutive abdominoplasties (n = 200) performed by a single surgeon was conducted. Liposuction of the abdominal flap and flanks was performed in all patients. After raising the abdominoplasty flap, undermining was performed to just beyond the xyphoid, lower rib margins superiorly, and to the anterior axillary line laterally. Fat deep to Scarpa's fascia was then removed by direct tangential excision in all zones of the abdominal flap.

Results: Average values included: Age, 42.19; BMI, 28.10 kg/m2; follow up, 7 months. Seroma occurred in 13 patients (6.5%), superficial wound dehiscence treated with local wound care in 16 patients (8%), hypertrophic scarring in 16 patients (8%), partial umbilical necrosis in one patient (0.5%), and partial umbilical epidermolysis in six patients (3%). No patients experienced major or minor full-thickness tissue loss. No patients needed reoperation.

Conclusions: Simultaneous direct excision of sub-scarpal fat with liposuction of the abdomen and flanks does not appear to subject any zone of the abdominoplasty flap to increased risks of vascular compromise. No flap necroses were observed. The use of our technique is safe and may provide superior abdominoplasty results.
