Objective: Secondary correction of cleft lip-nose presents a formidable challenge in cleft lip and palate surgery. Although numerous approaches have been proposed, suitable graft materials cannot be obtained from any part of body or the artificial biomaterials. We have established implant-type tissue-engineered cartilage using a porous scaffold comprised of poly L-lactic acid. The aim of this study was to primarily assess the safety of the autologous tissue-engineered cartilage when used in the cleft lip-nose patients as an exploratory first-in-human trial, and to explore the usefulness of the cartilage.
Methods: After the acquisition of institutional and governmental permission, we used this implant-type tissueengineered cartilage for the treatment of three cleft lip-nose patients. We examined whether or not serious adverse events had occur.. View More»
