Pterygoid sinusitis is one of the more common types of sinusitis today. It is difficult to eradicate with current medical conditions and its main symptom is a migraine, which is caused by the nerve reflex area of the pterygoid sinus near the frontal area. The initial stage of pterygoid sinusitis may be accompanied by a runny nose and sneezing. Especially in spring, the symptoms will be more obvious when inhaling pollen or fine dust, and this disease mostly occurs in the north of China. In the middle stage of the disease, there will be a dull pain in the head, and the flow of nasal discharge will increase, and it will be accompanied by nasal paroxysm, when the butterfly sinusitis is difficult to be detected and starts to affect the sense of smell. In the later stages of the disease, the patient’s intermittent headache becomes constant pain, difficulty sleeping, memory loss, possible vertigo when walking up stairs, and the sense of smell is severely affected with dark yellow nasal discharge, stiff facial expressions, and intensified tingling sensation during inhalation and exhalation, when x-rays are diagnostic. For different patients, there are differences in the size of the butterfly sinus and the severity of the disease. In short, butterfly sinusitis is difficult to cure, and it is easy to repeat after treatment. If it becomes chronic, it can be surgically removed; if it affects breathing, it can be expanded with an expander. Daily do not stay in the kitchen and restaurants with a lot of fumes, especially to avoid some irritating smells, such as perfume, aromatic balls, disinfectant, car exhaust, etc.
