This study aims to evaluate the effectiveness of nano-fat grafting in treating hypertrophic scars caused by burns on the chest, shoulders, and back.
Burn scars in these specific areas are often difficult to treat because the skin is under constant tension and motion, which can prolong inflammation and worsen the scar. While conventional scar treatments like silicone patches, pressure garments, and steroid injections are widely used, they do not always completely restore normal tissue. Nano-fat grafting is emerging as a promising regenerative option. This procedure involves taking a small amount of the patient's own fat and processing it into a liquid that is rich in healing cells. This liquid is then injected directly into the scar to potentially improve skin texture, color, and flexibility.
The study will enroll 55 participants between the ages of 18 and 50. To be eligible, patients must have a post-burn hypertrophic scar on their chest, shoulder, or back that is less than 6 months old.
During the study, doctors will harvest a small amount of fat from the patient's abdomen or thighs using a small tube. This fat will be carefully washed, processed, and passed through a special filter to create liquid nano-fat. The liquid is then gently injected into the scar tissue.
Researchers will monitor the patients and evaluate the scars at 1, 3, and 6 months after the injection. They will use standard clinical scar assessments (the Vancouver Scar Scale and the Patient and Observer Scar Assessment Scale) alongside photographs to measure improvements in scar color, thickness, pliability, and overall appearance, as well as patient-reported symptoms like pain and itching.
