Fat injection or lipoinjection to improve the quality of burn scar is the latest tool in the hands of a plastic surgeon.The fat contains regenerative cells including adult stem cells and helps in modulation of post burn scars.Fat injections use processed fat from the patient’s own body to the hypertrophic and itchy burn scars.
Fat grafting does result in dermal regeneration according to various studies.The procedure also is known as subcision and microlipoinjection or autologous fat transplantation. Fat cells are removed by liposuction from the donor area like around the navel or from the thighs or buttocks by using a cannula attached to a syringe. The fat cells are cleansed and processed, and then injected into the scar area using a blunt needle and syringe.Fat grafting also improves the skin grafted areas of deep burn scars.All three types of fat;millifat,microfat and nanofat can be used for burn scars depending upon the type of scar.
In a further refinement of the procedure,the fat derived regenerative cells are separated from the fat and only these cells are injected into the post burn scars.The scars improve over a period of few months after this procedure and the results are satisfying in most cases.It is seen to reduce the hypertrophy of the scar and reduces the pain and itching as well.
