Treatment of Benign Melanocytic Hyperplasia of Nail Apparatus with Dr. Hoon Hur’s Golden Parameter Therapy

Abstract

Background: Benign melanocytic hyperplasia (BMH) of nail apparatus may be caused by a lentigine in the nail matrix. Traditional treatment modalities including surgical excision and CO2 laser ablation may cause a severe scar of nail apparatus.There is no clear treatment for BMH of nail apparatus. Objectives: This study was performed to investigate the efficacy and safety of Dr. Hoon Hur’s Golden Paramter Therapy (GPT) with a high fluence 1064nm Q-switched Nd:YAG laser (QSNL) for treating BMH of nail apparatus . Study design: The medical records of 52 Korean patients (age range: 21 to 60 year-old, mean age: 38.6 year-old) diagnosed with BMH of nail apparatus were reviewed retrospectively. Methods: All patients were treated with a 1064nm QSNL, on a weekly basis for 10-15 treatment sessions of Dr. HoonHur’s GPT. The parameters were a spot size of 7mm, a fluence of 2.2J/cm² and a pulse rate of 10Hz with three passes by a sliding technique (sliding GPT) and one pass by a pulse stacking technique (pulse-stacking GPT) over the BMH of nail apparatus. Results: At the time of the final treatment, all patients with BMH showed the complete removal of pigmented lesions without any side effects, such as purpura, crust, post-inflammatory hyperpigmentation (PIH), nail dystrophy and scarring. No recurrences were observed in any of the patients after a follow-up of 3-12 months. Conclusion: We suggest that Dr. Hoon Hur’s GPT with a high fluence 1064nm QSNL is a safe and effective new treatment for BMH of nail apparatus without side effects and recurrences.
