Nasal septum deviation is generally treated under general anesthesia through nasal septum deviation correction surgery. During the surgery, the patient experiences no pain. Typically, the surgery can be completed in about one to two hours; this is a routine procedure in otolaryngology. Nasal septum deviation is primarily caused by congenital developmental deformities of the nasal septum or trauma to the nasal septum sustained later in life. This condition leads to persistent and progressively worsening nasal congestion on both sides, along with sensations of swelling and a foreign body in the nasal passages. Severe cases can cause dizziness, headaches, and other related symptoms. A thorough examination at a hospital using an electronic rhinoscope and nasal bone CT scan can confirm the diagnosis. In severe cases of nasal septum deviation, correction surgery under general anesthesia is needed for a complete cure.
