Fat preserving by laser 1210-nm.

Introduction: The 1210-nm wavelength has absorption-affinity for Lipid-Rich Tissue and has demonstrated to stimulate adipocytes and mesenchymal cells of the subcutaneous tissue, with a new concept: Selective Photothermostimulation (SPS). The application in Liposuction of this wavelength is determined by its preservation of the integrity of adipocytes, making possible the use of these materials for fat grafting in Liposculpture, Breast Reconstruction or as filler in Face Rejuvenation, proven that this technique is less traumatic.

Materials And Methods: 102 patients diagnosed with lipodystrophy either associated to skin flaccidity or not were applied the 1210-nm diode laser (ORlight®) between June 2010 and August 2011. The protocol was followed and verified through ultrasound imaging. Intraoperative and subcutaneous cellular tissue temperatures were measured. Samples of the aspirated tissue were sent for histological analysis to prove alteration/preservation of adipocytes and connective tissues, including mitochondrial activity.

Results: Histological analyses revealed 98% preservation of aspirated adipocytes. The 1210-nm diode laser shows affinity for adipose tissue. In addition, the technique poses a reduced trauma level on tissues, allowing for the performance of associated procedures for the body or face. No major complications were observed; and only minor complications, mainly ecchymosis on 2% of the total body surface area, have been recorded. The recovery period is 24 hours. The Liposuction Diode Laser (LSDL) 1210-nm is ideal for Liposculpture.
