Figure 19: (a) Longitudinal histological section of septum 4 weeks after resection of central 10 mm. Edematous mucosal layer (lamina propria); partial confluence of the two
perichondrial layers, partial filling with newly formed cartilage at both ends of the original cartilage. (b) Histological section of septum 2 weeks after resection of 1–2 mm. Overlap of fragments; demarcation of the necrotic area at the stumps. (c) Longitudinal histological section of septum 1 week after resection and re-implantation of crushed middle one-third. Vital clusters of cartilage cells next to necrotic pieces of tissue with proliferation of chondroblasts. Hematotxyline-azophloxine and Pas-Alcian Blue staining, magnification 4x.
