A comparative clinical and mycological study of Nd-YAG laser versus topical terbinafine in the treatment of onychomycosis.

BACKGROUND

Topical treatment of onychomycoses is time consuming, cost-intensive and subject to relatively high failure rates. Light-based devices may be effective treatment modalities. Aim of this work: To compare the clinical and mycological efficacy of Nd-YAG laser versus topical terbinafine in the treatment of onychomycosis.

PATIENTS AND

METHODS

This study included 40 patients with onychomycosis randomized to receive four sessions of Nd-YAG laser (group A) or topical terbinafine twice daily for six months (group B). Follow-up was performed monthly. Mycological examination was done at third and sixth months following the start of treatment.

RESULTS

After six months, all patients in group A showed marked improvement, while in group B only 50% of patients showed mild to moderate improvement. In addition, by the end of six months, 80% of the patients in group A showed mycological clearance, while all patients in group B still had positive cultures.

CONCLUSION

Long pulse Nd-YAG laser therapy of onychomycosis is a safe and efficient method for treating onychomycosis. It is especially beneficial in elderly, compromised and hepatopathic patients for whom other alternative treatments could present some risks.
