Complex open pilonidal wounds represent a challenging wound healing problem. Nine cases of complex open pilonidal wounds are described. Each of them was treated at the time of primary wide excision with placement of xenograft extracellular matrix material derived from urinary bladder (MatriStem, ACell Corporation). The patients left the xenograft material and dressings intact and returned to our clinic at weekly intervals for inspection of the wounds. All of the cases of complex open pilonidal wounds healed without infection and without requiring re-operation. The average time to healing in this series was 7 weeks. Treatment of complex open pilonidal wounds with MatriStem extracellular matrix derived from urinary bladder in this fashion results in favorable wound healing of complex open pilonidal wounds.
