Prevention of Thyroidectomy Scars in Asian Adults Using a 532-nm Potassium Titanyl Phosphate Laser

Abstract

Prediction of whether postoperative wound healing will result in a hypertrophic scar or keloid is difficult. Diverse treatment options have been developed in an effort to prevent excessive scar formation. To evaluate the efficacy and safety of a 532-nm potassium titanyl phosphate (KTP) laser in the prevention of scar formation after total thyroidectomy. Twenty-eight individuals with Fitzpatrick skin types IV and V and linear surgical suture lines after total thyroidectomy by the same surgeon were enrolled. Twenty participants were treated using a 532-nm KTP laser two times at 2-week intervals. Eight participants were assigned to the control group. The Vancouver Scar Scale (VSS), global assessment score (GAS), and participants' subjective satisfaction were used to determine the effect of scar prevention. These results were compared with those of the control group. The average VSS score was remarkably lower in the KTP laser treatment group. Average GASs indicated better cosmetic outcomes in the treatment group. Participant satisfaction was also higher in the treatment group. No significant side effects were observed during follow-up. A 532-nm KTP laser can be used safely and efficiently on Asian skin to reduce scar formation after thyroidectomy. The authors have indicated no significant interest with commercial supporters.
