[Laser Therapies for Onychomycosis in Japan]

Area of Science:

• Dermatology
• Medical Technology

Background:

• Onychomycosis (nail fungus) treatment traditionally involves oral and topical antifungal medications.
• Mechanical and chemical nail debridement are alternative methods.
• Laser therapies are emerging as a novel treatment modality for onychomycosis.

Purpose of the Study:

• To review the current landscape of onychomycosis treatment, focusing on non-antifungal approaches.
• To evaluate the reported outcomes and limitations of laser therapies in onychomycosis management.
• To identify areas for future research in laser-based onychomycosis treatments.

Main Methods:

• Review of existing literature on onychomycosis treatment methods.
• Analysis of studies reporting on laser therapies, including carbon dioxide laser, photodynamic therapy, and Nd:YAG laser.
• Examination of combination treatments involving lasers and antifungal drugs.

Main Results:

• Favorable outcomes have been reported in Japan for laser therapies (CO2, photodynamic, Nd:YAG) and combination treatments.
• Significant variability exists in irradiation conditions, session numbers, and efficacy evaluation across studies.
• One study indicated superior efficacy for Nd:YAG laser combined with external antifungal drugs compared to monotherapy.

Conclusions:

• Laser therapies present a potential alternative for onychomycosis treatment, but robust clinical evidence is lacking.
• Further research is essential to validate laser efficacy, assess combination therapy benefits, and explore treatment duration reduction.
• Standardization of treatment protocols and evaluation methods is crucial for establishing laser therapies in clinical practice.
