Deviated septum occurs when the thin wall (nasal septum) between your nostrils is displaced to one side. A deviated septum can block one side of your nose and reduce airflow, causing difficulty breathing. Nasal obstruction can occur from a deviated nasal septum, from swelling of the tissues lining the nose, or from both.
Most septal deformities you do not have symptoms, and you may not even know you have a deviated septum. The most common symptom is nasal congestion, with one side of the nose being more congested than the other, which results in difficulty breathing. Recurrent or repeated sinus infections can also be a sign of a deviated septum.
If a person has a deviated septum and it causes breathing problems or sleep apnoea and snoring, surgery may be recommended to correct the septum. The other options are to manage symptoms with nasal sprays.
Decongestants should be avoided for long term use as they can lead to a rebound effect.
Nasal steroid are a prescription nasal corticosteroid sprays can reduce inflammation in your nasal passage and help with obstruction or drainage. It usually takes from one to three weeks for steroid sprays to reach their maximal effect. Steriods are safe to use for long term use.
