Novel Use of Porcine Urinary Bladder Matrix in the Exenterated Socket

The aim of exenteration reconstruction is to stabilize the postsurgical wound bed to promote expeditious healing particularly in patients who are undergoing adjuvant radiation and/or chemotherapy. Porcine urinary bladder matrix has previously been used successfully as a wound-healing scaffold in treatment of burns and in acute, chronic, and surgical wounds, but the use of these products has not previously been reported in the exenterated orbit. The authors present a case of the novel use of porcine urinary bladder matrix in a pediatric patient who underwent exenteration for recurrent embryonal rhabdomyosarcoma, subsequent split-thickness skin grafting, and adjuvant radiation.
