Nasal Septum Deviation

Nasal septum deviation (deviation of nasal septum) refers to a nasal septum that deviates from the midline and causes clinical symptoms. In fact, most people have nasal septum with different degrees of deflection, but whether it causes nasal symptoms depends on the following factors: ① The degree and form of deflection, if there are obvious local protrusions, the part is in the nasal valve Area; ② the degree of turbinate gasification; ③ whether there is deformity in the bone of the lateral border of the piriform foramen or cartilage in the nasal valve area.
