The main reason that a deviated septum causes headaches
In clinical practice, a deviated nasal septum can be structural, which often leads to symptoms such as nasal congestion, nosebleeds, and headaches. There are primarily two reasons why a deviated nasal septum may cause headaches. First, the deviated septum directly irritates the middle turbinate, leading to anterior ethmoid nerve syndrome and severe headaches. Second, the deviated septum may lead to secondary conditions such as rhinitis or sinusitis, which also cause headaches. Therefore, in clinical practice, surgical intervention is needed to correct a deviated nasal septum causing headaches. Before surgery, a CT scan is usually conducted to rule out sinusitis or other diseases causing the headaches. However, it is important to inform patients preoperatively that even after the surgery, headaches caused by the deviated septum may not be completely relieved or eliminated. This is crucial information to communicate to patients before the procedure.
