Description

This is the supplemental tables of "Minimal Invasive Removal of Leukotrichia followed by Hair Transplantation: A Novel Two-step Surgery in the Treatment of Stable Follicular Vitiligo". The word document introduced the materials and methods of the manuscripts. Table S1 showed the patients demographic and clinical characteristics. Table S2 indicated the patients' satisfaction with the cosmetic results after surgery.In the follow-up procedure, the vitiligo patches were assessed for the aspect of leukotrichia by the camera and the dermatoscope at 12 months after the transplantation (Medical Electronic Dermatoscope Imaging System, CH-DSIS-2000, Chuanghong Medical Technology Co., LTD, Guangzhou, China). Patient satisfaction was documented on a questionnaire based on the visual analogue scale (VAS) ranging from high dissatisfaction to high satisfaction with the outcome. Supplemental Figure 1. Follicular vitiligo. Overview of the two-step surgery treating with the patients with stable follicular vitiligo. Initially, hairs of the vitiligo lesion were shaved to 2–4 mm. After disinfecting and local anaesthetizing, an incision was made around or in the center of the vitiligo scalp with 11# scalpels. The length of the incision should not exceed half of the diameter of the lesion, and the depth of the incision should reach the subcutaneous layer. Both blunt and sharp separation of the subcutaneous tissue of the scalp was performed about 1cm exceed the range of leukotrichia, and the residual tissue attaching to the dermis was resected by the ophthalmic scissors. Then a 497 mm fenestrated cup curette was used to scrape back and forth against the undermined flap for the subcutaneous trimming until the white hairs were easily pulled out. After sufficient hemostasis and washing, the incision was sutured and bandaged with moderate pressure. The wound was rinsed by the Iodine-containing disinfectant three days after the surgery, and the suture was removed 7-9 days after operation. Hair transplantation through the FUE technique was performed into the vitiligo area when the incision healed 1-3 months later. Before disinfecting, hairs of the occipital donor site were shaved to a length of 1 mm. Anesthesia was finished in both the donor and recipient sites by tumescent fluid containing 0.2% lidocaine with 1:100,000 epinephrine. The hair grafts were obtained by using a 1-mm hollow punches. The grafts were picked by the micro-forceps and placed in iced Ringer’s solution. After being drilled by a 1.2-mm needle, the recipient sites were implanted grafts in the distribution accordingly to presupposed density of 35–45 FUs/cm2. The recipient sites were applied with the topical antibiotics for 2–3 days and the dressing were removed postoperatively on the third day. Supplemental Figure 2A.
