Cerebrospinal fluid leakage, including traumatic cerebrospinal fluid leakage and spontaneous cerebrospinal fluid leakage, can be treated conservatively if the trauma is relatively mild and the vital signs are stable, and surgery is often considered if there is no obvious sign of spontaneous healing after 4 weeks of dynamic observation and if the patient meets the indications for surgical treatment. Traumatic cerebrospinal fluid leakage can sometimes be cured by conservative treatment, including lowering the cranial pressure and preventing infection. This may include lowering the cranial pressure and preventing infection, such as lying in a head-high position, limiting water and salt intake, avoiding forceful coughing and nose blowing, and preventing constipation. Long-term cerebrospinal fluid leakage will lead to bacterial meningitis, so those who have not been cured by conservative treatment for 2 to 4 weeks or who have repeated episodes of intracranial infections should undergo surgical treatment. After the occurrence of cerebrospinal fluid leakage, you should go to the hospital in a timely manner, and the doctor will find out the cause and the extent of the disease, and then take targeted treatment.
