Porcine Urinary Bladder Extracellular Matrix for the Salvage of Fibula Free Flap Skin Paddle: Technical Note and Description of a Case

Rabie M Shanti et al. Craniomaxillofac Trauma Reconstr. 2017 Dec.

Abstract

This report establishes a novel application of a commercially available porcine urinary bladder extracellular matrix, MatriStem (ACell, Inc., Columbia, MD), in the salvage of partial loss of the skin paddle of a fibula osteoseptocutaneous free flap that was utilized for mandibular reconstruction.

Keywords: MatriStem; fibula free flap; urinary bladder extracellular matrix.
