Partial empty butterfly saddle is empty butterfly saddle syndrome, a long-term, chronic degenerative change. It can be clinically asymptomatic, or it can manifest as headache, vision loss, and endocrine dysfunction. Due to abnormal development of the saddle diaphragm, or due to infection, increased intracranial pressure, or endocrine factors, the subarachnoid space is herniated into the pterygoid saddle, which fills the pterygoid saddle with cerebrospinal fluid. Clinically, there may be no obvious symptoms, or headache, vision loss, endocrine dysfunction and so on. When there are no obvious symptoms, it is only necessary to identify and treat the primary disease. When headache occurs, oral non-steroidal drugs such as ibuprofen can be taken; when vision loss occurs, adhesion release surgery can be taken. If the examination confirms the diagnosis of partially empty butterfly saddle, it is recommended to go to the hospital in time, under the guidance of the doctor for standardized treatment, the above drugs should not be taken on their own.
