The Use of Acellular Urinary Bladder Matrix as Coverage for Fasciocutaneous Free Flap Donor Sites: An Alternative to Traditional Grafting Procedures

The use of urinary bladder matrix is a viable option for the rehabilitation of donor sites of vascularized tissue that include skin. Benefits include the avoidance of an additional skin graft donor site, facilitation of epithelialization over exposed tendons, leveling of the donor site texture, and an equivalent esthetic result compared with current practices for wound coverage. The success of this technique may be limited by the cost of materials and the protracted course for wound epithelialization.
