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.

摘要：
背景：部分切除和化学基质切除术被认为是治疗II-III期向内生长的脚趾甲（IT）的金标准。然而,很少有报道描述硝酸银在青少年IT管理中的使用。我们的目的是分析硝酸银进行基质消融的有效性，并将其与通过电灼进行的部分切除术进行比较。
方法：对患有II-III期IT的青少年患者进行回顾性研究。比较了在大型门诊手术中心（A组）接受电灼基质切除术的人和在门诊接受硝酸银治疗的人（B组）。疗效由复发率和术后感染率决定。
结果：共纳入两百零九例患者（A组86例；B组123例），共有382例部分检查（A组151例；B组231例）。B组患者的复发率（4.7%）低于A组（11.2%，p=.02)，术后感染率较低(A组4.0%vs.B组1.7%；p=.18)，虽然没有统计学意义。
结论：男性部分切除术后的硝酸银化学基质切除术是治疗青少年IT的有效方法，术后并发症少，复发率低。因此,它应该被认为是一种可能的替代电灼矩阵切除术。
