Assessing the effectiveness of supertension-relieving suture technique in minimizing scar formation following melanocytic nevi excision

To evaluate the efficacy of the supertension-relieving suture (SRS) technique in reducing scar formation following melanocytic nevi excision. A total of 120 patients with melanocytic nevi were included and categorized into the SRS group ( n = 71) and the CON group (conventional suturing, n = 49). At 12 months postoperatively, the CON group exhibited physiological changes of natural scar remodeling: PSAS, OSAS, POSAS, and VSS scores decreased from 39.41 ± 5.21, 36.51 ± 3.76, 75.92 ± 6.79, and 11.86 ± 2.06 to 8.14 ± 1.57, 5.98 ± 1.48, 14.12 ± 2.06, and 1.81 ± 0.77, respectively; scar width increased from 2.12 ± 0.62 to 2.78 ± 0.84 mm, everted wounds decreased from 8.75 ± 0.76 to 0.94 ± 0.26 mm, and 9 complications occurred. In contrast, the SRS group showed improved remodeling: PSAS, OSAS, POSAS, and VSS scores declined from 40.21 ± 4.92, 36.51 ± 4.13, 76.72 ± 6.00, and 11.43 ± 2.15 to 6.52 ± 1.28, 4.31 ± 1.21, 10.83 ± 1.83, and 1.17 ± 0.60, respectively. Meanwhile, hyperplasia was reduced, scar width only changed from 1.95 ± 0.56 to 2.36 ± 0.71 mm, everted wounds decreased from 8.92 ± 0.91 to 0.72 ± 0.16 mm, with 3 complications. Compared with the CON group, the SRS group had significantly lower PSAS, OSAS, POSAS, and VSS scores, narrower scars, less wound eversion, and fewer complications at postoperative 3, 6, and 12 months. The SRS technique improves scar healing after melanocytic nevi excision, contributing to better cosmetic outcomes and fewer complications than conventional suturing methods.
