The Treatment of Infantile Cafe Au Lait Spot Using Dr. Hoon Hur’s Golden Parameter Therapy with a High Fluence 1064nm Q-Switched Nd: Yag Laser

Background: Infantile Café-Au-Lait Spot (CALS) is a benign hyperpigmentary skin disorder that ranges in color from light brown to dark brown. Using traditional laser therapies including 532nm potassium titanyl phosphate(KTP) laser, 694nm ruby laser and 755nm alexandrite laser for infantile CALS treatment may provoke harmful side effects such as purpurae, crusts,Post-Inflammatory Hyperpigmentation (PIH), mottled hypopigmentation and scarring. Unfortunately, there is no clear standard for the laser treatment of infantile CALS because an infant is too young to receive laser treatment. Objectives: This study was performed to investigate the efficacy and safety of Dr. Hoon Hur’s Golden Parameter Therapy (GPT) with a high fluence 1064nm Q-switched Nd:YAG laser laser (QSNL) for infantile CALS treatment. Methods: Nineteen Korean patients with infantile CALS were enrolled in this study and treated with a 1064nm QSNL on a weekly basis for 20-50 treatment sessions of Dr. Hoon Hur’s GPT. The parameters were a spot size of 7 mm, a fluence of 2.2 J/cm2 and a pulse rate of 10Hz with one pass by a sliding-stacking technique over the infantile CALS. Results: After the final treatment, all of the 19 patients with infantile CALS were achieved the complete removal of pigmented lesions without any side effects such as purpurae, crusts, PIH, mottled hypopigmentation or scarring. No recurrences were observed in any of the patients after a follow- up of 6-14 months. Conclusion: We suggest that Dr. Hoon Hur’s GPT with a high fluence 1064nm QSNL is a safe and effective treatment for infantile CALS without causing side effects and recurrences.
