Particle size, temperature, released amount of fat for safe periorbital fat graft

초록

The aim of this study is to determine the particle size, temperature, and amount of released fat for safe periorbital fat grafts. Methods: From 28 patients, fat was suctioned from the abdomen (large particles, LP) and from the inner thigh (small particles, SP) using a 2.1mm harvesting cannula with a diameter 3.2mm×1.4mm hole and a 1mm hole, respectively. The 10-cc syringes full of fat were then put into a centrifuge for 3 min (LP) and 1 min (SP) at 3000 rpm. Fat was then transferred to a 1cc syringe with Luer Lock adapters and a blunt cannula of 0.9mm diameter. The force needed to push the fat out of the cannula was measured with a force gauge. The force was measured according to different groups according to particle size of the fat, temperature of the fat, and released amount of fat.
