Background: Split-thickness skin graft (STSG) is a fundamental and versatile technique used in reconstructive surgery. Despite numerous studies addressing the management of STSG donor sites, there is still little consensus on the optimal dressing method. This study aimed to analyze the effectiveness of a novel method that combines a fenestrated polyurethane film with negative-pressure wound therapy (NPWT) over conventional moist dressings.Methods: Between January 2021 and December 2022, 23 patients who received STSG were retrospectively reviewed. In group A, a polyurethane film punctured with a 20-gauge needle was applied to the skin graft donor site. A NPWT system (CuraSys) was subsequently applied over the film. The conventional NPWT was replaced with a portable NPWT (PICO system) on the day of discharge. On the 14th postoperative day, the NPWT and film were removed. In group B, patients were administered a traditional moist dressing until epithelization. Postoperative pain, reepithelization rate, and dressing cost per cm² were compared.Results: Group A exhibited a lower mean pain score on all the measured days. Furthermore, group A demonstrated a significantly shorter time required for complete reepithelization (18.07±8.43 days vs. 28.20±5.25 days, P=0.003) and a lower dressing cost per square centimeter (6,517±6,162 KRW [4.82±4.56 USD] vs. 23,036±27,157 KRW [17.05±20.11 USD], P=0.006).Conclusion: The combination of fenestrated polyurethane film and NPWT resulted in reduced pain caused by dressing, a faster reepithelization rate, and lower dressing cost than that of conventional moist dressing.
