Abstract
We report a case of spontaneous cerebrospinal otorrhea occurring in an adult.
An 83-year-old male complained of hearing loss on the left side and fluid was detected in the left middle ear. The middle ear fluid was positive for glucose, suggesting that it was cerebrospinal fluid. CT revealed a bony defect in the temporal bone and a slight effusion in the left mastoid. At the first operation, the site of leakage could not be confirmed and only granulation was found. Therefore, we judged that the ear discharge was associated with chronic otitis media. However, a few days later, fluid in the wound appeared again, and we diagnosed cerebrospinal fluid otorrhea, and performed a second operation. When the part that seemed to be defective was carefully observed, a small amount of leakage was confirmed. The defect was repaired by packing with fascia, bone and fatty tissues with fibrin glue.
No recurrence has been observed for 1 year after the surgery.
