Objective To explore the clinical efficacy of local deck window surgery for subungual hemangiomas.Methods A retrospective analysis was performed on data of 9 patients with subungual hemangiomas from October 2019 to February 2022.All patients underwent local deck window surgery,and postoperative clinical efficacy was evaluated by observing wound condition,pain relief[visual analogue scale(VAS)score],recovery of the nail bed,and patient satisfaction during follow-up.Results Postoperative follow-up showed good wound healing without nail bed infection,disappearance of pain,and good nail growth for all patients.The mean preoperative VAS score was significantly higher than that at 2 weeks and 2 months postoperatively(P<0.05).One patient developed nail bed deformity after surgery,but all patients were satisfied with the results.Conclusion Local deck window surgery for subungual hemangiomas has good surgical efficacy,significant pain relief,and high patient satisfaction,and is worth promoting and applying in clinical practice.
