Nanofat on Wound Healing and Scar Formation

Nanofat on Wound Healing and Scar Formation: a Randomized, Split-scar, Double Blind Trial

This study will evaluate the effectiveness and safety of intradermal injection of Nanofat on wound healing and scar formation.

In this monocentric, randomized, controlled, double-blinded prospective interventional study, twenty patients will be included. Each patient will be his/her own control.

Patients undergoing DIEPflap breast reconstruction will be included in this study. During the surgery, the abdominal incision will be divided in two equal sides with the umbilicus as midline reference. The sides will be randomized in a treatment side and control side. The treatment side will receive intradermal nanofat injections after the subcutaneous and right before the intradermal sutures.

The patient and investigators will be blinded for the treatment protocol. The effects on wound healing, adverse events, scar formation and pigmentation will be evaluated up to one year after the surgery.
