The nasal septal cartilage has no regenerative ability because this cartilage has no regenerative ability, but the nasal septal mucosa has regenerative ability because the septal cartilage is clinically done to remove the deviated cartilage, and after it is removed, this cartilage will not continue to grow, that is, the removed cartilage is removed and will not grow automatically later. However, if the septal cartilage is missing or part of it is missing after surgery, it does not affect the function of the nasal cavity or the appearance of the nose, etc. However, for the septal cartilage, if the nasal mucosa is broken after the septal deviation surgery, the septal perforation complication should be prevented in this case.
