Use of 3-Dimensional Imaging in Submental Fat Reduction Following Hyperthermic Laser Lipolysis

摘要： In a randomized controlled study, patients with a wide variety of hypopigmented scars, and striae alba had mean final pigment correction rates of approximately 100% by colorimetric analysis after 9 treatments of 308-nm excimer laser biweekly. However, maintenance treatment every 1 to 4 months is suggested because the pigment gradually declined toward baseline values during a 6-month follow-up. Although the authors performed 308-nm excimer light only once weekly for 6 times in our patient, she had a good response and rapid repigmentation within 3 months, and no recurrence of hypopigmentation was found at a 10-month follow-up. A possible hypothesis is that she had no genetic predisposition for vitiligo, and she had a darker Fitzpatrick skin type. Patients with Fitzpatrick skin Type III and above generally respond better to an excimer laser than those with lower skin types. To the best of our knowledge, this is the first case of corticosteroid-induced perilymphatic linear hypopigmentation treated with 308-nm excimer light.
