In clinical practice, there is no specific food that can effectively improve the condition of wide posterior cranial fossa, because it is not theoretically a disease state. There are many people with wide posterior cranial fossa due to congenital developmental abnormalities, and others may have wide posterior cranial fossa due to cystic compression, which can be treated with regular follow-up, unless there are significant clinical symptoms, which require surgery. There is no medication that can completely improve it, nor is there food that can completely improve it. In some individual cases, it may be caused by tumor compression and can only be radically solved by surgery. Therefore, it is important to clarify the trend of changes in one’s condition for better treatment.
