Cerebrospinal Fluid Post Traumatic Otorrhea:

Discharge of cerebrospinal fluid through the external auditory meatus or through the eustachian tube into the nasopharynx. This is usually associated with CRANIOCEREBRAL TRAUMA (e.g., SKULL FRACTURE involving the TEMPORAL BONE), NEUROSURGICAL PROCEDURES, or other conditions, but may rarely occur spontaneously. (From Am J Otol 1995 Nov;16(6):765-71)
