[0002] Cerebrospinal fluid is a colorless transparent liquid that exists in the ventricles and subarachnoid space. Cerebrospinal fluid otorrhea is often caused by middle cranial fossa fractures involving the tympanic cavity. Because the petrous bone is located at the junction of the middle and posterior cranial fossa, no matter the middle fossa or posterior fossa of the petrous bone is fractured, as long as the middle ear cavity is injured, bloody cerebrospinal fluid may enter the tympanic cavity. In this case, the patient should lie on the affected side and wait for natural healing. In this way, cerebrospinal fluid will continue to leak out, which will not only cause bloody fluid to contaminate the bed unit, but also easily lead to intracranial infection if not handled properly.
