Bilateral submucosal cysts in the pterygoid sinus can be observed and reviewed regularly if they are small and do not affect the normal function of the surrounding tissues; if they are large or cause other complications, they can be treated by endoscopic pterygoid sinus cyst removal. Pterygoid sinus cysts are generally considered to be benign lesions, and the rate of malignant changes is very low; as long as there is no compression of the surrounding tissues, then regular observation is good; if there is any compression of the local tissues, or if it has an impact on the usual life, then surgical resection can be carried out, such as endonasal endoscopic resection of pterygoid sinus cysts. Usually pay attention to the living environment if the temperature difference is big, pay attention to keep warm, avoid cold; pay attention to do not exertion, keep emotional stability. If you have symptoms of physical discomfort, you should go to the hospital in time, under the guidance of the physician, to clarify the cause and give targeted treatment.
