Effects of ND:YAG laser irradiation on the fat tissue

PO291 EFFECTS OF ND:YAG LASER IRRADIATION ON FAT TISSUE Francesca Romana Grippaudo1, Nicolò Scuderi2 1 University of Rome ‘La Sapienza’ 2nd Faculty of Medicine and Surgery, 2 University of Rome ‘La Sapienza’, 1st Faculty of Medicine and Surgery Background and objective In the past decades surgical procedures to remove undesired at bulges have become the most performed aesthetic procedure in Western Countries, employing the liposuction, the ultrasound assisted lipoplasty, the external ultrasonic liposuction, the pneumatic assisted liposuction. All these techniques have a risk to be aggravated by local and general complicances and they request a long recovery time. Some patients are willing to have ‘something done’ to reduce the undesired bulges but are refusing any major surgical procedure and its sequelae. In order to reduce the traumaticity associated with this surgical act, the 1,06 μm Nd:YAG laser radiation addressed to selectively destroy the fat tissue was investigated. Study design/materials and methods The effects of a Nd:Yag laser wavelength 1064 nm delivered to the fat tissue through a 300-μm fiberoptic inserted into a small cannula were evaluated in this study. The cannula was inserted in the subcutaneous tissue, and the energy was applied on human adipose tissue to be taken from lipectomy samples of 10 healthy women. The tissue samples were irradiated for 20 min prior their ablation for the elective scheduled surgery procedure with a criss-cross technique, and were studied using the protocols of traditional hystology and scanning electron microscopy. Nonirradiated tissue samples were taken and processesed for reference. Results All specimen showed that after laser exposure the adipocytes appears destroyed, the cells in the interstitial space and the capillaries remained intact. Conclusion Nd:YAG laser-assisted lipoplasty has produced the selective destruction of fat tissue.
