The only treatment for a deviated nasal septum is surgical correction. If there are nasal polyps or turbinate enlargement at the same time, nasal polyps and turbinate surgery should be performed first. If ventilation improves and nasal symptoms disappear, no treatment is required. Corrective surgery is suitable for: (1) People with long-term persistent nasal congestion caused by nasal septum deviation. (2) Those that affect sinus drainage and cause chronic sinusitis. (3) Cause repeated epistaxis or secretory otitis media. (4) Reflex headache caused by compression of the inferior turbinate, which is ineffective after conservative treatment. (5) Patients with hay fever, perennial rhinitis or bronchial asthma have severe nasal septum deviation that is ineffective after other treatments. However, surgery is not suitable in the following situations: (1) Patients with acute intranasal infection. (2) Untreated sinusitis. (3) Certain systemic diseases such as diabetes, tuberculosis, severe hypertension, etc. (4) Cardiac insufficiency, blood disease, etc. (5) Female patients are during menstruation. (6) Persons under 18 years old.

Surgical methods: ① Submucosal septal resection; ② Swinging door surgery; ③ Submucosal septal correction or plasty.

Postoperative care such as anti-infective treatment and timely dressing changes after surgery should also be taken seriously.
