The Effectiveness of Matrix Cauterization With Bichloracetic Acid in the Treatment of Ingrown Toenails.

BACKGROUND: Chemical matricectomy is performed mainly by 2 agents, phenol and sodium hydroxide. Chemical matricectomy with phenol has a low recurrence rate and good cosmetic results, but it produces extensive tissue destruction and can result in drainage and a delayed healing time. These adverse effects have brought forward the use of chemical agents such as sodium hydroxide and trichloroacetic acid for matricectomy. OBJECTIVE: This prospective study aimed mainly to evaluate the efficacy of partial nail avulsion and selective chemical cauterization of the matrix using 90% bichloracetic acid (BCA) in the treatment of the ingrown nails. MATERIALS AND METHODS: A total of 30 patients with 58 ingrown toenail edges were included in this study. All of the patients underwent chemical matricectomy with 90% BCA after partial nail avulsion. Adverse effects such as postoperative pain and drainage were minimal in most of the patients. RESULTS: One patient who underwent matricectomy had recurrence in a single nail edge (1.8%) at the 12th month of the follow-up. No recurrence was observed in 29 patients during mean follow-up period. This was considered to be statistically significant (p
