Patients who have a very pronounced deviation of the nasal septum have certain hazards, mainly including the patient’s nasal ventilation function is particularly poor, and often have symptoms of nasal congestion, headache, and sometimes a runny nose. If the deviation of the nasal septum is obvious, local contact with the inferior turbinate often results in nasal bleeding. If the nasal cavity is poorly drained because of the deviated septum, it is easy to form sinusitis. If the deviation is indeed obvious and the patient’s symptoms are severe, surgery can be considered. The surgery requires general anesthesia, and the bones of the deviated septum will be removed under nasal endoscopy. After the surgery, the patient needs to return to the hospital for regular review, and in about half a month’s time, the patient’s condition will improve significantly.
