Laser-Assisted Liposuction (LAL) Versus Traditional Liposuction: Systematic Review

Liposuction is the most performed surgical procedure in Brazil and the second in the world. In recent years, new technologies have been developed in an attempt to improve liposuction, such as laser. The objective of this study is to evaluate the efficacy and safety of laser-assisted liposuction (LAL) compared to traditional liposuction through a systematic review of the literature.

The search strategy used was the combination of the descriptors [lasers (MeSH Terms)] and (lipectomy [MeSH Terms]) in the PubMed database. Two independent researchers carried out the reading of the abstracts and selection of the studies according to the eligibility criteria. The risks of study bias were evaluated using an instrument similar to that used by the Cochrane Collaboration.

Initially, 80 studies were obtained and, after evaluating the eligibility criteria, seven remained. Five of them observed that LAL has benefits when compared to traditional liposuction, and the main outcomes were compared with regard to histological analysis (2 products), further reduction of subcutaneous fat (2), better retraction of the skin (3), and higher personal satisfaction of the patient (2). The qualitative assessment identified high risks of bias in various areas in the studies.

Although studies have concluded that LAL promotes greater fat reduction, better skin retraction, and greater patient satisfaction compared to traditional liposuction, the high bias impedes a more reliable conclusion.
