Abstract

For treatment of ingrown toenails, a phenolization approach is often chosen. Many reports describe a lavage of the wound with alcohol to neutralize any residual phenol; however, it remains uncertain if there is a more effective solution for use in the lavage step. The aim of our study was to analyze the suitability and effectiveness of 0.1% polihexanide solution compared with isopropyl alcohol in the removal of excess phenol after treatment for ingrown toenails. We performed an in vitro study using human matrix and a diffusion cell apparatus to measure the amount of phenol remaining after two lavage washes. The effect of phenol evaporation was also examined.When phenol was irrigated with alcohol alone, 27.43 ± 4.10 mg (57.74%) of the initial amount of phenol was recovered. If irrigated with 0.1% polihexanide, 35.98 ± 2.93 mg (75.74%) of phenol was recovered. These results indicate that a polihexanide lavage step has significantly higher efficiency for removing excess phenol relative to alcohol.
