Split-thickness skin grafts (STSG) are commonly used to treat soft-tissue defects. Harvesting a STSG creates an additional partial thickness wound at the donor site which must be managed. Many dressings are commercially available for the management of STSG donor sites; however, there is no evidence-based consensus on optimal dressing for site management. Urinary bladder matrix (UBM) is an extracellular matrix that acts as a structural support for tissue remodeling and provides molecular components for repair. Common clinical applications of UBM include coverage of deep wounds, burns, and irradiated skin. Skin grafting from the lower extremities poses a challenge due to the increased dermal tension. UBM-based reconstruction is an alternative method of managing lower extremity skin graft donor sites. This case study demonstrates the use of UBM in the reconstruction of a STSG donor site of the anterolateral thigh, which resulted in satisfactory healing, no pain, and excellent cosmetic and functional outcomes.
分层皮片移植(STSG)常用于治疗软组织缺损。采集分层皮片会在供皮区造成一个额外的部分厚度伤口,必须对其进行处理。市面上有许多敷料可用于分层皮片供皮区的处理;然而,对于供皮区处理的最佳敷料,尚无基于证据的共识。膀胱基质(UBM)是一种细胞外基质,可作为组织重塑的结构支撑,并为修复提供分子成分。UBM的常见临床应用包括覆盖深度伤口、烧伤和受辐射皮肤。由于皮肤张力增加,下肢取皮存在挑战。基于UBM的重建是处理下肢皮肤移植供皮区的一种替代方法。本病例研究展示了UBM在大腿前外侧分层皮片供皮区重建中的应用,其结果是愈合良好、无疼痛,且美容和功能效果极佳。
