Abstract：
BACKGROUND: Onychocryptosis is a common pathological condition requiring clinical intervention. Selecting an appropriate and effective treatment based on individual patient circumstances is crucial.
METHODS: We compared the efficacy and safety of the modified Noel\'s technique and matrix phenolization in 107 participants with onychocryptosis. Participants were divided into two groups: 75 nails (73 patients) were treated with the modified Noel\'s technique (modified Noel\'s group), while 42 nails (34 patients) were treated with matrix phenolization (Phenol group). Outcomes on clinical cure rates and postoperative complications from both groups were collected. Additionally, the efficacy of the modified Noel\'s technique was assessed in 31 nails with stage IV onychocryptosis.
RESULTS: After 18 months, among the remaining 102 patients (110 nails), the modified Noel\'s group exhibited fewer complications (5.88% vs. 45.2%, P < 0.001) with similar cure rates (P = 0.62). Furthermore, there was a shorter healing time in the modified Noel\'s group (13.5 ± 1.4 vs. 27.6 ± 2.3 days, P < 0.001). Postoperative pain was notable in the modified Noel\'s group on the first postoperative day (P < 0.001), with a significant decrease in the pain score 2 weeks after surgery (P = 0.407). Postoperative nail plate narrowing was observed in the Phenol group (33%). Moreover, the modified Noel\'s technique achieved a 100% cure rate in stage IV patients.
CONCLUSIONS: The modified Noel\'s technique, offering precise excision of the proliferative nail fold and strategic suturing, is suitable for stage IV patients and for those who find significant aesthetic impact unacceptable following narrowed plate postmatrix phenolization.

摘要：
背景：Onychocryposis是一种需要临床干预的常见病理状况。根据患者的具体情况选择适当和有效的治疗方法至关重要。
方法：我们比较了改良Noel's技术和基质酚化的有效性和安全性在107名患有甲癣的参与者中。参与者分为两组：75个指甲（73名患者）采用改良的Noel's技术（改良的Noel's组），而42指甲（34例）采用基质酚化治疗（酚组）。收集两组的临床治愈率和术后并发症的结果。此外,改良Noel技术的疗效在31例IV期甲癣患者中进行了评估。
结果：18个月后，在其余102名患者中（110个指甲），改良的Noel组并发症较少(5.88%vs.45.2%,P<0.001），治愈率相似（P=0.62）。此外，改良Noel组的愈合时间较短(13.5±1.4vs.27.6±2.3天，P<0.001)。改良Noel组术后第一天疼痛明显(P<0.001),术后2周疼痛评分显著降低（P=0.407）。在苯酚组(33%)中观察到术后钉板变窄。此外，改良的Noel技术在IV期患者中实现了100%的治愈率。
结论：改良的诺埃尔技术，提供精确切除增生性指甲褶皱和战略缝合，适用于IV期患者和在窄板后基质酚化后发现不可接受的显着美学影响的患者。
