[Orthotopic cartilage transplantation. Morphologic, angiography and histochemical studies of the vitality of free septum transplants].
Orthotopic cartilage transplantation is a technique frequently used in modern septal surgery. The prerequisite for a stable long-term result is viability of the transplanted cartilage. Therefore, we studied the healing process histologically, angiographically, and histochemically. We found a characteristic picture. Due to chondronal structure of the cartilage, the healing process varied in time and location. Reintegration took place by chondroneogenesis, commencing at the inner perichondrium. Reintegration depended directly on the distance of the cartilage cells to the surrounding vessels. Histochemically, we found an intact respiratory chain in the mitochondria and thus, we were able to demonstrate the preservation of viability in orthotopic transplanted cartilage.
