{Abstract}: BACKGROUND: Partial onychectomy with chemical matrixectomy is considered the gold standard treatment for stage II-III ingrown toenails (IT). However, there are scarce reports describing the use of silver nitrate in IT management in adolescents. Our aim is to analyze the effectiveness of matrix ablation with silver nitrate and compare it with partial onychectomy by electrocautery.
METHODS: A retrospective study of adolescent patients with stage II-III IT was performed. Those who underwent electrocautery matricectomy in a major outpatient surgical center (Group A) and those who were treated with silver nitrate at an outpatient clinic (Group B) were compared. Efficacy was determined by recurrence and postoperative infection rates.
RESULTS: Two hundred and nine patients were included (86 group A; 123 group B), with a total of 382 partial onychectomies (151 group A; 231 group B). Group B patients exhibited a lower recurrence rate (4.7%) when compared to group A (11.2%, p = .02), and had a lower postoperative infection rate (4.0% group A vs. 1.7% group B; p = .18), although not statistically significant.
CONCLUSIONS: Silver nitrate chemical matricectomy after partial onychectomy is an effective treatment for IT in adolescents, with few postoperative complications and low recurrence rate. Therefore, it should be considered as a possible alternative to electrocautery matricectomy.
