The treatment of Erythema ab igne using Dr. Hoon Hur’s golden parameter therapy with a high fluence 1064nm Q-Switched Nd: YAG Laser

Erythema ab igne (EAI) is a skin condition caused by long-term exposure to heat without thermal burn. Prolonged thermal radiation exposure to the skin can lead to the development of reticulate erythema, hyperpigmentation, scaling and telangiectasia in the affected area. Generally, the outcome of treating EAI with some topical agents including tretinoin cream and imiquimod cream was not satisfactory. Unfortunately, there is no standard laser therapy for EAI 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 EAI, this study was performed. Eleven Korean patients with EAI were treated with a 1064nm QSNL at a one-week interval for 20 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 EAI. At the week of the final treatment, all of the 11 patient with EAI were achieved the complete clearance of reticulate hyper 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 6-10 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 EAI.
