{Abstract}: <B>BACKGROUND: </B>Onychocryptosis is a common pathological condition requiring clinical intervention. Selecting an appropriate and effective treatment based on individual patient circumstances is crucial.<BR><B>METHODS: </B>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.<BR><B>RESULTS: </B>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.<BR><B>CONCLUSIONS: </B>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.
