Background: Laser lipolysis is a new commonly used and accepted modality for removal of unwanted fatty tissue.

Aim: The aim of this study was to evaluate the safety and efficacy of the 980 nm diode laser for lipolysis.

Materials and methods: From May 2013 to November 2014, 56 patients underwent laser lipolysis. The treatment was performed using a 980 nm diode laser (OSYRIS, Hellemmes, France). After tumescent anesthesia, a 0.8 mm diameter microcannula housing a 600 μm optical fiber was inserted into the subcutaneous fat. The cannula was moved back and forth in a predetermined manner to get a homogeneous distribution of energy at the treated area. Laser settings were selected in relation to individual body areas: 6 W (chin, arm, leg), 9 W (abdomen, back, lower back), 15 W (hips, buttocks). Patient satisfaction was evaluated and side effects were recorded.

Results: One hundred and five (105) laser lipolysis procedures were performed on 56 patients. Different areas were treated: lower back (25), abdomen (24), legs (16), submental area (11), back (9), buttocks (8), arms (7), knees (2), ankle (1). Mean cumulative energy was area-dependent, ranging from a minimum of 2500 J to a maximum of 45000 J. Ecchymoses were observed in almost all patients but resolved in under one week for all patients. Hypertrophic scarring occured in a patient on the incision area. Burns were observed in a patient on the submental area. Contour correction and skin retraction were observed in five patients. There was no infection, hypopigmentation, bruising, swelling or edema. Patients’ satisfaction was very high. Patients were able to resume normal daily activities after 24 hours.

Conclusion: This clinical study showed that the removal of small volumes of unwanted fatty tissue can be performed safety and effectively using a 980 nm diode laser. We observed excellent patient tolerance and quick recovery time in this study.

Key words: Lipolysis, 980 nm, diode laser.
