Summary

The subject's neck thyroidectomy incision was bisected along the anterior midline. One side received 1565 nm non-ablative fractional laser treatment, designated as the study side, according to a computer-generated randomization scheme, while the other side received a sham treatment (the laser device emitted sound only, without delivering any energy), serving as the control side. Outcome indicators were recorded during follow-up, along with any related adverse events and/or reactions occurring during and after the treatment. The aim was to evaluate the effectiveness and safety of the 1565 nm non-ablative fractional laser in the treatment of postoperative thyroid scars.
