Cerebrospinal fluid ear leakage is a serious condition. When cerebrospinal fluid ear leakage occurs, it means that the intracranial and extracranial areas have been communicated, and bacteria can enter the cranium through the leak and there is a risk of intracranial infection. Intracranial infections can have serious consequences such as high fever and coma, and uncontrolled infections can be life-threatening, so cerebrospinal fluid ear leakage is a relatively serious disease. However, it can be cured. After cerebrospinal fluid leakage, the patient should be absolutely bedridden, choose a proper head position to keep the cerebrospinal fluid from flowing out, and if necessary, do lumbar pool drainage and use antibiotics to prevent infection. Most patients with cerebrospinal fluid aural leakage will stop after two weeks of treatment, but a small number of patients will continue to have cerebrospinal fluid aural leakage, and surgery should be considered if the aural leakage has not healed for more than one month.
