The septum divides the two sides of the nose. A deviation is common and often harmless, but a significant deviation can obstruct airflow.
Symptoms to look out for
Persistent blockage on one side, mouth breathing, disturbed sleep, recurrent sinus infection or nosebleeds.
Treatment options
Medical treatment for associated allergy or swelling is often the first step.
Where obstruction remains significant, septal surgery may be discussed, depending on symptoms and examination findings.
Common questions
Does a deviated septum always need surgery?
No. Surgery is considered only when the deviation causes meaningful symptoms that do not improve with medical treatment.
