Material and methods: We conducted a prospective, comparative trial of the long-term efficacy of two methods: phenolization (88%) and matricolysis by trichloroacetic acid (TCA) (100%). Adult, consenting patients with ingrown toenails were alternately allocated into two treatment, to receive either 88% phenol or 100% TCA chemical matricectomy. The patients as well as the statistician were blinded to the agent being used. Post-procedure follow-up evaluated median duration of pain, discharge, and healing along with recurrence, if any, in both the groups. The group wise data was statistically analyzed. Results: On comparing the two groups, pain lasted 9.34 days in the TCA group and 18.62 days in the phenol group, this difference was not statistically significant (P = 0.202). The tissue condition took 9.30 days to normalize in the the TCA group, while it took 17.63 days to normalize in the phenol group. This difference was found to be statistically significant (P < 0.007). The aesthetic result and the cost of the care were similar in the 2 groups. Conclusion: Chemical matricectomy using TCA is as efficacious as phenolisation, with the advantage of faster tissue normalization. %G en %J Our Dermatology Online %A Moustaide, Kaoutar %A Aqil, Niema %A Gallouj, Salim %A Mernissi, Fatima Zohra %D 09.04.2019
