Background:
Ingrowing toenails can be treated with conservative therapy or surgery, but frequent relapse can be a problem in conservative therapy and surgical therapy without matricectomy. Thus, permanent nail ablation by partial matricectomy is now accepted as the treatment of choice.
Objective:
To evaluate the efficacy and safety of trichloroacetic acid (TCA) matricectomy in the treatment of ingrowing nail.
Materials And Methods:
Forty ingrowing toenail edges in 25 patients were enrolled. TCA matricectomy with 100% trichloroacetic acid after partial nail avulsion was performed. For a few weeks after surgery, postoperative complications such as pain, discharge, and infection were assessed. After a mean follow-up period of 22.9 months, recurrence rate and cosmetic outcomes were investigated to evaluate the effects of the surgery.
Results:
The wounds almost always healed within 2 weeks without prolonged exudative discharge. Pain was mild and transient. A case of secondary infection occurred. Recurrence was found in only two nails of one patient, and the success rate was 95%, with good cosmetic results.
Conclusion:
TCA matricectomy showed a low recurrence rate with minimal side effects and was easy to perform in outpatient clinic. Therefore, it may be a good alternative treatment of ingrowing toenails.
