Low-level laser-assisted liposuction: the Neira 4 L technique.

Low-level laser-assisted liposuction (LLLL), known as the Neira 4 L technique, is an excellent adjuvant tool for the surgeon practicing liposculpture. A low-level laser is used to create a transitory pore in the cell membrane of the adipocyte to move fat from inside the cell to the interstitial space outside without killing the cell. LLLL has been performed successfully in in-vitro and human adipose tissue cultures. It protects the patient from the surgical trauma of liposuction by protecting and preparing tissues for the surgical trauma; modulating the inflammatory response to prevent short and long-term side effects of surgery; and improving the quality and quantity of the healing process by accelerating recovery time, modulating secondary cicatrization, and preventing postoperative neuralgias.
