Treatment and Prevention of Umbilical Sagging with Laser-assisted Liposuction: The New Happy Protocol

Sagging of the periumbilical skin, also known as the “sad umbilicus,” is one of the most common postoperative complications in liposuction. It is characterized by an increase in the width and decrease in the height of the umbilicus. Technological advances in power-assisted liposuction resulting in skin tightening have been central to improvements in the treatment of sagging skin. Laser-assisted liposuction is a procedure in which a laser fiber induces lipolysis and skin tightening. Laser treatment delivered using a 980-nm diode laser may result in up to 30% skin surface area contraction. The aim of this study was to describe a new technique called the “happy protocol” for the treatment and prevention of the sad umbilicus. The periumbilical region is treated using a 980-nm diode laser set to an output power of 20 W, with a total delivered energy of 5000 J. The developed technique may be applied to correct shape distortions or to create a natural-looking and aesthetically pleasant umbilicus during liposuction. A decrease in the width of the umbilicus followed by an increase in height are observed in the first postoperative days. Patients who were followed up for 7 months postoperatively showed positive aesthetic results. The final outcome was an oval-shaped umbilicus, with increased height and reduced sagging in the periumbilical region.
