Pak J Med Health Sci Jan ;13(4):982-4.

Aim: To compare the efficacy of 90% Trichloroacetic acid and 88% phenol in Matrixectomy (extraction of partial nail) for the management of ingrown toe nails. Methods: This was a single center prospective randomized clinical study, conducted in the General surgery department of Pakistan Institute of Medical Sciences Hospital, Islamabad, from July 2018 to July 2019. Out of all study participants 50% patients treated with 88% Phenol and the remaining 50% treated with 90% Trichloroacetic acid. Postoperatively patients were followed for 48 hours, 1, 4, 12 weekly up to 3 months. Efficacy was defined in term of pain wound bleeding, allergic reaction, wound infection and recurrence. Data was collected on self -designed Proforma. Results : Total 100 patients of ingrown toe nails were selected. Average age of patients was 26.31±8.74 years. Severity of the pain was statistically insignificant among both groups, p -value 0.472. Wound infection was higher in 88% Phenol group in contrast to 90% Trichloroacetic acid group, while statistically insignificant, p-value 0.306. Recurrence was only among 2 patients of 90% Trichloroacetic acid group. Conclusion: Both treatment options are equally effective in treating the ingrown toenails with lower rate of postoperative pain , complications and recurrences .
