After removal of the nasal septum, first of all the cartilage in its middle will have a lack of support. If too much is obtained, it can also lead to a serious situation of nasal collapse. Moreover, if the septum removal process is violent or the removal method is improper, there is also a possibility of breaking the blocking effect in the middle of the septum, resulting in septal perforation, which may also lead to repeated inflammation and infection in the perforated nose, as well as nasal bleeding, abscess and other complications. If the perforation is large, there will be some nasal whistling sound, which will also affect the quality of life in general.
