Abstract: 【Abstract】 Objective To investigate the clinical efficacy of the Winograd procedure combined with a modified suturing technique and health education in the treatment of ingrown toenail-induced paronychia. Methods From November 2021 to December 2022, 84 patients with ingrown toenail-induced paronychia （stages IIA and above according to the Mozena classification） were collected from the Department of Dermatology, General Hospital of Eastern Theater Command. All patients received the Winograd procedure combined with a modified suturing technique and health education, and were followed up for 6 - 12 months after surgery. Changes in the visual analog scale （VAS） pain scores over time were analyzed using repeated measures analysis of variance, and pain intensity data assessed using a 4-point verbal rating scale were analyzed using the Kruskal-Wallis H test. Results During the follow-up period, 78 out of 84 （92.9%） patients were completely cured, 3 （3.6%） achieved improvement, and 3 （3.6%） experienced relapse. The pain intensity was significantly reduced at 1 month and 3 months after operation compared with that before operation （H = 8.65, 8.64, both P < 0.001）; the VAS pain scores were 0.44 ± 0.09 and 0.16 ± 0.04 points at 1 month and 3 months after operation retrospectively, which were both significantly lower than the preoperative scores （6.18 ± 0.24 points, both P < 0.001）. Four cases developed local infections, and were cured after dressing changes. Conclusion The Winograd procedure combined with a modified suturing technique and health education was effective for the treatment of ingrown toenail-induced paronychia, with a low recurrence rate after surgery, and the operative and suturing techniques were simple and practical.
