Immediate reconstruction of segmental mandibular defects via tissue engineering. Academic Article uri icon

abstract

  • Ameloblastomas are benign, locally invasive odontogenic tumors that comprise approximately 1% of tumors within the jaws, with 66% located in the posterior mandible. If left untreated, these lesions can reach enormous size, resulting in considerable deformity and associated morbidity. Traditionally, defects >6 cm warranted a free-flap fibula transfer or iliac crest autogenous graft. Surgical treatment for the two presented cases included a large (>6 cm) mandibular segmental resection with immediate reconstruction via a tissue-engineering protocol that included bone morphogenetic protein (rhBMP-2), bone marrow aspirate concentrate, and cortical bone chips. Both patients had an uneventful postoperative course and healed satisfactorily. Established bone reconstruction determinants include bone volume, facial counter, esthetics, and restoration of functionality. Advances in tissue engineering provide a legitimate alternative while decreasing the risks, length of hospital stay, and postoperative morbidity.
