Subsurface Fractional Ablative Resurfacing of a Periareolar Scar Using 1,064-nm Picosecond Laser with Micro-Lens Array

ABSTRACT

Although picosecond lasers were invented as an effective treatment of pigmented lesions, the Food and Drug Administration has also approved picosecond lasers with fractional mode for treating acne scars and wrinkles on the face. In this report, we introduce a noteworthy case in which we treated a periareolar scar using a 1,064-nm picosecond laser with fractional mode. A 32-year-old female patient who had a periareolar scar due to a breast reconstruction procedure with a latissimus dorsi myocutaneous flap hoped to remove the postoperative scar. We applied a 1,064-nm picosecond neodymium-doped yttrium aluminium garnet (Nd:YAG) laser with a micro-lens array (MLA) to the scar twice, with a 1-month interval between treatments. The scar improved after the second laser treatment and the patient was satisfied with the outcome. The treatment of a postoperative periareolar scar through subsurface fractional ablative resurfacing using a 1,064-nm Nd:YAG picosecond laser with a MLA produced significant improvements in the texture and aesthetic appearance of the scar, without any wound complications.
