Abstract: 【Abstract】 Objective To investigate clinical efficacy of nail removal in combination with periungual dermis-fat flap tamponade in the treatment of bilateral severe curved ingrown nails. Methods A retrospective analysis was conducted on clinical data collected from 7 patients with bilateral severe curved ingrown nails at clinic visits between January 2018 and January 2020. There were 3 males and 4 females, aged 25 - 49 years （average: 35 years）. All patients were treated with nail removal in combination with periungual dermis-fat flap tamponade at outpatient clinics. Results All the 7 patients experienced primary healing of incisions without infections, and achieved pain relief 1 - 2 weeks after surgery. During the follow-up of 12 to 24 months, new nail plates grew back without curling deformity, no erythematous swelling occurred in the nail grooves, and no recurrence of paronychia was observed. All patients were satisfied with the clinical efficacy. Conclusion Nail removal in combination with periungual dermis-fat flap tamponade is effective for the treatment of bilateral severe curved ingrown nails.
