Headache is a symptom that we all encounter, some headaches are related to fatigue and cold, some are related to overuse of the brain, some are caused by diseases of the head, sometimes, diseases in other parts of the body can also cause headache attacks, this cause often requires the exclusion of many diseases, therefore, sometimes it is true that the patient has a headache and the doctor feels the headache, the cause is not easy to find. One type of headache is not familiar to patients. This type of headache can be seasonal and related to the nasal cavity, especially when the temperature changes, and there are some children who suffer from headaches and memory loss, which leads to a drop in academic performance. Parents are anxious and take their children to the hospital with brain ultrasound, cerebral hemogram, and even cranial CT examinations, but the results do not reveal the problem until they go to the ENT department to find out that the headache is caused by rhinitis or sinusitis. This kind of headache caused by nasal diseases is called rhinogenic headache, and the most common causes of rhinogenic headache are chronic rhinitis and sinusitis. In fact, it is common for nasal disorders to trigger headaches. When factors such as swelling or hypertrophy of the nasal mucosa and sinus mucosa after a cold, and obstruction of sinus ventilation and drainage stimulate the trigeminal nerve endings on the mucosa of the nose and sinuses, headaches can occur due to reflex action. When there are lesions in the nasal cavity or sinuses, such as sinusitis and nasal polyps, the headache is easily caused by continuous tension contraction of the head and neck muscles due to poor sinus drainage, and the headache is aggravated by lack of oxygen due to nasal obstruction and poor breathing when suffering from acute and chronic rhinitis. These conditions can often be detected by routine examination of the nasal cavity. Deviated nasal septum tends to obstruct sinus openings and impede sinus ventilation and drainage, which can cause obstructive headaches. High septal deviation and compression of the turbinate mucosa by the crestal prominence can also cause reflex headache. In atrophic rhinitis, the nasal cavity is wide, and a large amount of air inflow can stimulate the nasal mucosa and cause reflex headache. When the nasal cavity is blocked by flat scabs and secondary infection, not only the nasal ventilation is not smooth but also there is a foul smell, which can cause obstructive headache. The location of rhinogenic headache is mostly in the frontal area, face and nasal root, and the pain is more regular, such as the headache caused by frontal sinusitis, which is heavier in the morning, less in the afternoon, and significantly less at night, and the symptoms increase when the head is lowered. Prevention of rhinogenic headache should start from prevention of cold and flu, and timely treatment of rhinitis in the acute stage to avoid development of chronic rhinitis; also do not buy nasal drops casually to delay the condition leading to drug rhinitis. In the early stage of rhinogenic headache, local medication can be used to improve nasal obstruction and the headache can be relieved. In addition, if there are anatomical abnormalities or nasal polyps, surgical treatment should be performed. In conclusion, when there is an unexplained headache, attention should be given to whether the headache is caused by nasal diseases, and one should go to a specialist for consultation or further examination to clarify. Generally speaking, headaches caused by nasal diseases can be cured.
