Leakage through the nose or ears following trauma usually gets better with rest. Antibiotics are given if an infection is present. If the leakage persists, the doctor may place catheters in the lumbar spine to reroute the CSF. Surgical closure of the ruptured membrane is rarely needed. If leakage is caused by erosion due to tumor or infection, the underlying cause must be treated.
Infection of the trauma site and failure of the rupture to close spontaneously may sometimes occur. In cases of a skull fracture, swelling may damage a cranial nerve, leading to weakness or paralysis on the side of the face. These injuries commonly result in hearing loss on the affected side.
Treatment is usually successful, although complications such as infection can occur.
A person should be monitored for infection and recurrence of CSF leakage. A change of therapy may be needed if infection or recurrence takes place. Any new or worsening symptoms should be reported to the doctor.
