Combination treatment with autologous fat grafting and nonablative 1,540-nm erbium laser significantly improves the appearance of facial traumatic and acne scars and provides high patient satisfaction, according to the outcomes of a study published in the Journal of Cosmetic and Laser Therapy (March 22, 2022).
Yoav Gronovicha and Adi Maisel Lotan of the department of plastic and reconstructive surgery, Shaare Zedek Medical Center in Jerusalem, Israel, performed the prospective study of 16 patients (mean age of 42 years) with either traumatic (73%) or acne induced (27%) scars. The authors noted that the traumatic scars were mainly new scars, with the majority of patients were treated within 30 days of injury.
All subjects underwent treatment with autologous fat grafting and nonablative 1,540-nm erbium laser. The treatment protocol included fat injection followed by five treatments with the erbium laser (ICONTM Cynosure; Westford, MA) starting one month after the fat injections. Patients were evaluated before treatment, after treatments and six months after the final treatment.
There were no reported complications. Scars improved in both texture and appearance, and patient satisfaction was high in all cases.
