A deviated septum can cause headaches. Patients with deviated nasal septum often have intermittent and persistent nasal congestion on one or both sides, increased nasal secretion and decreased sense of smell, and in severe cases, tilting of the nasal bridge and dislocation of the nasal columella are seen. The characteristics of deviated septum headache are mainly based on the different types of deviated septum and the performance is different, the etiology of deviated septum leading to headache is as follows: 1, mechanical compression: such as the nasal septum is spiny or spiny protrusion, direct stabbing of the inferior turbinate or partial flexion side of the inferior turbinate compression, causing a reflex headache; 2, breathing airflow from the anterior nostrils into the nasal cavity, a large amount of cold air into the side of the deviation of the concavity, overstimulation of the mucous membrane of the nasal cavity, stimulate the Nasal nerve endings cause headache, can also cause reflex headache; 3, high deviation of the nasal septum in the upper nasal cavity narrowing, resulting in sinus openings blocked ventilation, drainage obstacles secondary to sinus infection, mucosal swelling, stimulation of peripheral nerves and severe headache. The headache is mostly in the arch of the eyebrow, medial orbital, nasal dorsum, due to the compression of the nasociliary nerve, headache caused by deviated septum to look for the cause of the disease, and come to the hospital in time to diagnose and treat.
