Segmental phenolization of ingrowing toenails: A randomized controlled study

Abstract

One hundred and three patients, on whom 107 procedures for ingrowing toenails were performed, were randomly allocated into one of two treatment groups: segmental or angular phenolization and wedge excision. There were 53 wedge excisions and 54 segmental phenolizations. Post-treatment discomfort was assessed on a linear analogue scale of 10 cm. There was no difference between the two groups one week after treatment. Over a mean follow-up period of 14 months a total of 20 nail spikes occurred, 4 in the phenolized group and 16 in the wedge excision group, this being a significant difference at the one per cent level.
