Morphologic aspects of the injured nasal septum in children.

Biopsies from the septal cartilage in children have been examined histologically to study the influence of trauma, surgery, septal abscess, and transplantation on the growing cartilage. Loss of cartilage, complete, but mostly incomplete regeneration of the defects are the main reactions. A regenerative potential mainly arising from the perichondrium plays an important factor for restoring the septal structure, often in a deforming and excessive way. Even preserved cartilage implanted immediately into the septal abscess, may be transformed into autogenous cartilage if the perichondrium is preserved.
