Hi, Deviated nasal septum and allergic rhinitis usually go hand in hand. Treatment of nasal obstruction may include medications or adhesive strips to manage symptoms. But to correct a deviated septum, surgery is necessary. Medications offered initially include decongestants to relieve congestion, steroid sprays, anti-histaminics. Sometimes if septum is deviated too far as in your case then surgery is advised. The level of improvement you can expect with surgery depends on the severity of your deviation. Symptoms due to the deviated septum — such as nosebleeds, obstruction — often completely resolve. However, any accompanying nasal or sinus conditions — such as allergies [allergic rhinitis]— can t be cured with surgery. Even there are chances that bone can regrow again in future. So discuss with your ENT surgeon regarding this, and take a decision. But if symptoms are very severe then surgery is option. I hope I have answered your query, in case you have doubt I would be happy to help you. Take care. Best regards, Dr. Neelam.
