MORETTI, Ernesto et al. Effect of high level surgical ultrasound in dermic and fat tissue: experimental study for use in abdominal marking. Cir. plást. iberolatinoam. [online]. 2016, vol.42, n.3, pp.227-232. ISSN 1989-2055.

Background and Objectives. The concept of abdominal marking or six packs has increased its demand among patients who consult for body contouring. The use of ultrasound assisted lipoplasty third generation has improved results in body contouring and has achieved greater definition of the treated areas. But this is not exempt of complications, such as skin burns. Our aim is to demonstrate the power and time of detrimental cutaneous contact with the patient's skin. Methods. We developed an experimental study in 15 dermolipectomy specimens using powers of ultrasound at 70 y 100% and modifying action on the dermis exposure time from 15 to 30, 45 and 60 seconds These areas were studied by histopathology. Results. Our data showed that at 100% power and 15 seconds next to the skin, epidermolysis (2 degree burns) was developed, while the safety ranges (no histological changes) were observed using 70% power and 60 seconds in direct contact with the dermis. Conclusions. This paper intends, through an experimental study, giving security settings when using surgical ultrasound for liposuction in the proximity of cutaneous areas.
