Extracted from the Wikipedia article Otitis media.
Signs and symptoms
Acute otitis media with perforation of the eardrum, chronic suppurative otitis media, tympanostomy tube otorrhea, or acute otitis externa can cause ear discharge. Trauma, such as a basilar skull fracture, can also lead to cerebrospinal fluid otorrhea (discharge of CSF from the ear) due to cerebral spinal drainage from the brain and its covering (meninges).
