Similar short-term as well as long-term postoperative treatment outcomes were observed between the one-minute applications of 10% sodium hydroxide (NaOH) vs 88% phenol groups.

• This study included 62 ingrown toenail sides treated with 10% NaOH and 56 ingrown toenail sides treated with 88% phenol.

• Mean follow-up span was 25.17 months.

• Recurrence occurred in four nail sides of the NaOH group (%6.45) and three nail sides of the phenol group (%5.35) but the difference between the recurrence rates was not statistically significant.

• On post-procedural tenth day, there was absence of pain among patients treated with both methods.

• Between two groups, visual analog scale pain scores and complete healing duration were found to be similar.
