The human body has four pairs of sinuses, namely the maxillary sinus, septal sinus, butterfly sinus and frontal sinus. Chronic septal sinusitis is actually a type of chronic sinusitis. Most chronic sinusitis is due to the presence of abnormalities in the anatomy of the sinus-oral nasal tract complex of the middle nasal tract, which occurs as a result of impaired drainage, causing chronic inflammation and the presence of mucosal hypertrophy. Chronic septal sinusitis in the true sense of the word is a condition in the gill chamber of the septal sinus, mucosal hypertrophy, which rarely causes subjective clinical symptoms. If there are clinical manifestations, they may be only a mild feeling of dizziness or pain, or discomfort at the root of the nose. Most are due to dizziness or other causes, and mucosal hypertrophy is found in the septal sinuses when a CT or MRI is done. If there are no clinically significant symptoms of nasal congestion, runny nose, olfactory disturbance, and headache, the images can be closely observed without excessive treatment for the time being.
