The nasal septum can be removed. When a deviated septum occurs, the patient will experience nasal congestion and other symptoms, and will require a deviated septum correction procedure to remove the deviated septal cartilage and the patient will be cured. 90% of people have a deviated nasal septum, which is a bony tissue separating the left and right nasal cavities. The cause of deviation is mainly due to malformation of the fetus during development, and it may also be due to acquired nasal trauma or compression by nasal tumors. Deviated septum can be categorized as C-shaped, S-shaped and crural, which will lead to bilateral nasal congestion, reflex headache, chronic yellow nasal discharge, chronic sinusitis and other related symptoms. If the above symptoms are obvious, the patient needs to undergo surgical treatment, which includes correction of deviated septum and partial mucosal resection of bilateral inferior turbinate. It is important not to damage the symmetrical septal mucosa on both sides of the nasal septum during the surgery, as this can easily lead to perforation of the septum. The surgery requires general anesthesia, and the patient can be discharged after one week of hospitalization.
