The new treatment of cafe au lait spot using dr. hoon hur’s golden parameter therapy with a high fluence 1064nm q-switched nd: yag laser

The Café-au-lait spot (CALS) is a benign hyperpigmentary skin disorder which may vary in color from light brown to dark brown. Generally, treating CALS with traditional laser therapies including 532nm Nd:YAG laser, 694nm ruby laser and 755nm alexandrite laser can provoke side effects such as purpurae, crusts, post-inflammatory hyperpigmentation (PIH), mottled hypopigmentation and scarring. Unfortunately, there is no golden standard for the laser treatment of CALS yet. Therefore, in order to investigate the efficacy and safety of Dr. Hoon Hur’s Golden Parameter Therapy (GPT) using a high fluence 1064nm Q-switched Nd: YAG laser (QSNL) for treating CALS, this study was performed. Ninety-seven Korean patients with a solitary CALS were treated with a 1064nm QSNL at a one-week interval for 50 treatment sessions of Dr. Hoon Hur’s GPT. The parameters were a spot size of 7 mm, a fluence of 2.4 J/cm2 and a pulse rate of 10Hz with a slow single pass by a sliding-stacking technique over the CALS. At the week of the final treatment, all of the 97 patient with a solitary CALS were achieved the complete clearance of pigmented lesions without any side effects such as purpurae, crusts, PIH, mottled hypopigmentation and scarring. No recurrences were observed in any of the patients after a follow- up of 6-12 months. We suggest that Dr. Hoon Hur’s GPT using a high fluence 1064nm QSNL is a safe and effective method without side effects and recurrences for treating CALS.
