Most chronic sinusitis of more than ten years can be cured by rational treatment. Chronic sinusitis is a chronic inflammatory disease that occurs in the mucous membrane of the sinuses, which may cause symptoms such as nasal congestion, runny nose, smell dysfunction and headache, thus affecting the quality of life. The main treatment options for chronic sinusitis include medication and surgery. For patients with mild symptoms, drugs such as mometasone furoate and budesonide can be used, but they must be under the guidance of a professional doctor and must not be self-diagnosed. For patients with no obvious effect of drug treatment, surgical treatment can be taken, usually choose nasal endoscopic surgery. Sinusitis patients should go to the regular hospital in time, under the guidance of the doctor for targeted treatment.
