Deviated Nasal Septum
The septum is the wall between the two nostrils. When it is bent or off-centre, it can block airflow on one side and cause breathing problems.
Causes & risk factors

- Normal growth of the nose
- Previous nasal surgery or trauma
Common symptoms
- Blocked nose, often worse on one side
- Difficulty breathing through the nose
- Recurrent sinus infections
- Nosebleeds
- Snoring or poor sleep
Tests & diagnosis
- Nasal examination (nasal endoscopy)
- CT scan of the sinuses if needed
Treatment & management
- Decongestants or steroid sprays to ease congestion
- Saline nasal rinses
- Treating any linked allergy
- Surgery (septoplasty) to straighten the septum in significant cases
When to see a doctor urgently
- Constant one-sided blockage affecting sleep or breathing
- Frequent nosebleeds or sinus infections

Frequently asked questions
Does everyone with a deviated septum need surgery?
No. Many people have a mild deviation and no problems. Surgery is only considered when it causes significant blockage or repeated infections.
Can sprays fix a deviated septum?
Sprays cannot straighten the septum, but they can reduce congestion and improve airflow. Surgery is the only way to correct the bend itself.
