Outline of Final Research Achievements

The purpose of this study was to contribute to the development of a safe and effective correction harness for an abnormal auricle. Because the correction of the auricular cartilage seems to follow a process similar to cartilage reproduction and formation, a cartilage formation model was made with a rabbit’s auricle. To examine if vascularization was a factor influencing the formation of auricular cartilage, we evaluated the effects of matrix metalloproteinase (MMP) and vascular endothelial growth factor (VEGF), which are associated with vascularization, on cartilaginous formation by inhibiting these two materials. The inhibition of MMP and VEGF decreased the number of vessels around the perichondrium, and an increase in perichondrium cells and the differentiation of the chondrocytes were observed. In conclusion, vascularization seems to be strongly related to auricular cartilage formation.
