title: [A case report: a repeated cerebrospinal fluid otorrhea].
abstract: Cerebrospinal fluid (CSF) otorrhea, leakage of CSF through the ear structures, may occur from a traumatic or operative defect in the skull, tumor, cholesteatoma, or congenital anomalies. A case of repeated CSF otorrhea is uncommon. In this report, we presented a case of a repeated CSF otorrhea which occurred a decade after the first middle ear surgery for chronic otitis media. The first CSF leakage, which might have been due to bone defects in the tegmen at the first middle ear sutgery, was surgically repaired using a transmastoid approach. However, CSF leakage with a meningoencephalocele occurred again 8 years after our first surgery for the CSF and the fistula was repaired using a transmiddle cranial fossa approach. Although 2 years have passed since the surgery, the CSF leakage has not recurred.
