OBJECTIVE

To study morphological changes in quadrangular cartilage during its mechanical modeling using a press.

MATERIAL AND METHODS

Histological study of human cadaver septal cartilage was carried out in two age groups: 16—40 and 41— 60 years old.

The cartilages of each group were straightened using the special press. Flattening was carried out by one and two thirds of the original thickness of the cartilage and led to an increase in area of the autograft. The control group consisted of 10 intact specimens of quadrangular cartilage (5 in each age group). The preparations were fixed in 10% neutral formalin solution. Paraffin sections were stained with hematoxylin and eosin, according to Van Gieson for collagen fibers, with azure A and according to Hale for glycosaminoglycans, and a PAS reaction was performed for glycoproteins.

RESULTS

Flattening of the cartilage by one third of its original thickness does not lead to significant damage to chondrocytes, despite focal fractures of the interterritorial matrix in both age groups. Flattening by two-thirds causes deeper damage to the cartilage in the form of focal fragmentation into isolated areas while maintaining the macroscopic integrity of the graft. Changes were more severe in the second age group with significant areas of mechanically damaged cells and interterritorial matrix up to the formation of detrital masses.

CONCLUSION

Moderate flattening (by one third of the initial thickness of the cartilage) preserves the morphological structure of the cartilage tissue and ensures its ability to engraft and regenerate, regardless of age factors. Flattening the quadrangular cartilage by two-thirds changes the structure of the cartilage, depending on the age.
