Problem

Although lasers have been demonstrated to be useful in onychomycosis, management of onychomycosis still relies on oral antifungals and topical lacquer with slow clearance and poor cure rates. Contraindications to oral agents, prolonged treatment and their failure often lead to patient dissatisfaction. Fractional CO2 laser has been used in combination with topical antifungals for three to four sessions administered 4 weeks apart with a reported clearance of onychomycosis.[1] A modification reducing the repeated patient visits, consequent costs and better compliance is thus preferable.

Solution

Fractional CO2 laser utilizes water as its chromophore. In addition, urea, a hygroscopic agent, softens the nail plate and its occlusion helps provide water chromophore at depth, thus enabling the accelerated fungicidal effect of a fractional CO2 laser.[2]

The authors have been administering fractional CO2 laser treatment as a single session following 12% urea occlusion of the affected nail for 24 h with excellent results. The affected nail [Figure - 1]a is cleansed with saline, isolated from surrounding skin by applying a cutout of TegadermTM film [Figure - 1]b and [Figure - 1]c prepared according to the size, followed by application of preformulated 12% urea, and thereafter, occluded with a second layer of Tegaderm [Figure - 1]d and dressed in micropore. Next day the occlusion is removed, nail cleansed with saline and a single session of three passes of fractional CO2 laser (Cis F1-Fractional CO2 Laser, Sellas, Korea) using pulse energy of 110 mJ, (256 spots/cm[2], pulse interval of 0.5 mm, pulse duration of 0.1 ms) is administered over the diseased nail including 1mm normal appearing nail surrounding it [Figure - 2] and [Figure - 3]. 1% topical terbinafine cream is advised to be applied twice daily for 3 months. Cases were reviewed once every month. Analysis of Onychomycosis Severity Index score before and 6 months after session showed significant clearance at 6 months [Figure - 4].

This modality of single session fractional CO2 laser offers an alternative management for onychomycosis.
