Superficial subdermal liposuction (SSL) was presented by the authors as an evolution in traditional liposuction in 1989. It allows one to treat the superficial fat to obtain better skin retraction during every liposuction procedure. The use of ultrasound (US) in liposuction began 10 years ago as the direct application of this energy to the adipose tissue using a probe to obtain the selective destruction of fat, followed by its aspiration. This technique gave rise to many complications and thus many concerns. The external delivery of US has been proposed to overcome some of the drawbacks associated with this procedure. The authors investigate the role of external ultrasound (EU) used in conjunction with SSL. When comparing EU and SSL with SSL alone, pretreatment with EU results in less bleeding during liposuction, aspirated fat that is clearer and more oily, and less bruising and swelling during the early postoperative period. EU is an ideal complementary procedure to SSL because the crumbling of the fat induced by US permits a more uniform aspiration of the subdermal fat layer, making skin retraction more even and effective.
1989年，作者提出了皮下浅层吸脂术（SSL），将其作为传统吸脂术的一种改进。它能在每次吸脂手术中处理浅层脂肪，以实现更好的皮肤回缩。吸脂术中超声（US）的使用始于10年前，即通过探头将这种能量直接作用于脂肪组织，以实现脂肪的选择性破坏，随后进行抽吸。这项技术引发了许多并发症，也因此引发了诸多担忧。为克服与该手术相关的一些缺点，人们提出了超声外照射法。作者研究了联合使用超声外照射法（EU）与皮下浅层吸脂术（SSL）的作用。将超声外照射法联合皮下浅层吸脂术与单纯皮下浅层吸脂术相比较时，术前采用超声外照射法可使吸脂过程中出血减少，吸出的脂肪更清澈、更油腻，且术后早期的瘀伤和肿胀更少。超声外照射法是皮下浅层吸脂术的理想辅助手术，因为超声引起的脂肪破碎能使皮下脂肪层抽吸更均匀，使皮肤回缩更均匀、更有效。
