Many types of soft tissue grafts have been used for the reconstruction of oral mucosal defects. The best results are achieved with mucosal grafts; however, when large areas must be grafted, sufficient donor tissue is not available. Tissue engineering represents an alternative method to obtain sufficient autologous tissue for reconstructing oral wounds. Herein we present a pediatric patient with hemifacial microsomia and congenital ankyloglossia requiring multiple surgical interventions, and in which an autologous full-thickness tissue-engineered oral mucosa was used for successful oral reconstruction. Our study demonstrates that even under challenging conditions, robust tissue-engineered products, such as the fibrin-based oral mucosa described here, can achieve successful tissue regeneration. © Copyright 2014 American Cleft Palate-Craniofacial Association.
