Various treatment methods other than oral and topical antifungal medications have been employed to treat onychomycosis. Treatment methods include mechanical removal of the affected part of the nail plate by using a toenail cutter or grinder and chemical removal by using occlusive dressing therapy with salicylic acid plaster or urea cream. In recent years, laser therapies have received attention as modalities for treatment of onychomycosis. Favorable outcomes in patients with onychomycosis have been reported in Japan from treatment combining carbon dioxide laser and topical antifungal drug, treatment with photodynamic therapy, and treatment with Nd:YAG laser. However, irradiation conditions, number of irradiation sessions, and efficacy evaluation methods vary among institutions and studies; thus, there is no established evidence to support these outcomes. In addition, a study reported that a combination of Nd:YAG laser and external antifungal drugs was more effective than each of the treatments alone. Future studies are required to provide clinical evidence on the effectiveness of laser therapies, on the enhancement of effect from the combination of laser and external antifungal drugs, and on the possibility of shortening treatment duration using laser therapies in the management of patients with onychomycosis.
