Background: Since the first studies by Apfelberg in 1994, laser lipolysis (LAL) has been on the rise. Laser lipolysis leads to reduced operator fatigue, excellent patient tolerance, quick recovery time, as well as the additional benefit of dermal tightening. This article reports a 5-year experience of LAL and underlines the potential evolutions of the technique. Methods: Between January 2006 and December 2010, 674 LAL procedures in 359 patients were performed at the Antoni De Gimbernat Foundation in collaboration with the French National Institute of Health and Medical Research (INSERM) U703. LAL was performed with a 980-nm diode laser after tumescent anaesthesia. The following laser settings were used: 600-μm optical fiber, continuous mode, power depending on individual body areas (1840 W). The cumulative energy used for each area was recorded. Early and late complications were defined and reviewed for the whole series. Satisfaction was assessed by the patients using a visual analogue scale from 0 (unsatisfied) to 10 (highly satisfied). Results: Mean cumulative energy ranged from 12 to 60 kJ. Ecchymoses were observed in all patients but resolved in less than 10 days. A touch up was needed in four patients to remove small cushions of fat missed. Mean patient satisfaction ranged from 6/10 to 9.5/10 depending on the treated area. Moreover, all patients reported they would be willing to undergo the procedure again, if needed. Conclusion: 980-nm LAL appears to be a safe, effective and reproducible alternative to conventional lipoplasty. However, refinements in dosimetry should be developed in order to optimise outcomes.
