  • The nose is a complex three-dimensional structure and represents a major aesthetic focus of the face. As a gold standard for nasal soft tissue reconstruction, the 'forehead flap' provides reconstructive surgeons a robust pedicle and large amount of tissue to reconstruct almost any defect. However, during this process, some hair can be unintentionally introduced to the nose. Accordingly, laser hair removal is sometimes needed, but blood circulation and flap survival should be carefully monitored. Despite careful evaluation, a third-degree burn occurred in our patient that required eight weeks to heal. Here, we report on a burn resulting from epilation conducted 2 weeks after forehead flap for nasal reconstruction.

  • Background and Objectives The picosecond 755 nm alexandrite laser was first approved by the US FDA in 2012. A previous study described the use of a 1,064 nm picosecond laser with a micro-lens array (MLA) in peri-areolar scarring from breast reconstruction surgery and reported significant improvement in the texture and aesthetic appearance of the scar without other wound complications. The purpose of this study was to evaluate the improvement of overall scarring, not just pigmentation, in the picosecond laser treatment of patients with pigmentations. Materials and Methods Sixteen patients who underwent 1,064 nm picosecond laser treatment from June 2016 to December 2018 were enrolled in this study. Patients received two to six sessions of picosecond laser treatment at intervals of 4 weeks. Before and after the laser treatment, the patients evaluated their own satisfaction score and a physician evaluated the Vancouver Scar Scale. To evaluate the satisfaction score and complication rate, a retrospective chart review was done. Results Seven were female and nine were male. The mean of the patients' satisfaction score before the treatment was 1.44 (interquartile range [IQR], 1-2) and 3.00 (IQR 2.25-3.75) six months after treatment. The mean of the Vancouver Scar Scale before the treatment was 9.69 (IQR 8-11), and 6.25 (IQR 5-7.75) six months after treatment. All the results were statistically significant (p<0.01). Conclusion This study provides evidence that the use of a 1,064 nm picosecond laser treatment for pigmented scars can be effective in improving the pigmentation and overall scar status, including vascularity, height, and pliability, with the results of a decrease in the VSS scores between treatments.
