If a patient has allergic rhinitis combined with a deviated septum, the effect of medication alone will not be obvious. It is best to have surgery to correct the deviated septum, which will help the patient recover and improve the nasal ventilation. After the surgery, patients can spray mometasone furoate nasal spray with azelastine hydrochloride nasal spray to reduce the symptoms of allergic rhinitis, and can add anti-allergic oral medications, such as cetirizine hydrochloride capsules or desloratadine syrup, all have good effect. After the septum correction surgery, patients need to return to the hospital for regular review to clarify the recovery inside the nasal cavity to avoid causing postoperative adhesions in the surgical area to aggravate nasal congestion, and must avoid contact with allergens in life.
