[Septumplasty. Histologic changes in resected and reimplanted autologous septal cartilage and bone following crush injury].

The histological findings of the crushed deviated septal cartilage and bone are described directly after reimplantation between the mucoperichondrium periostium in septoplasty, and after 11, 16, 24 and 26 months as well as after 6 and 6.5 years. Immediately after crushing, multiple fractures different in width and damage of single cartilage cells and bone cells are visible. The crushed reimplanted material shows partial absorption and partial regeneration especially near the fracture lines over a period of several years. Months and years after reimplantation, the following can be observed: vascularised connective tissue grows into the fractures, metaplastic bone production and a new growth of cartilage-like plates are visible at the crushed cartilage, primary and secondary bone production are visible at the crushed bone. Clinically, a stable plate of bone and cartilage is seen after septoplasty in the reimplantation zone. The importance of reimplantation of crushed material in septoplasty is emphasised.
