측두골 외상후 진주종성 중이염으로 오인된 중이강내 뇌허니아 1예 = A Case Report of Brain Herniation into the Middle Ear Mimicking as Secondary Cholesteatoma Following Temporal Bone Fracture

다국어 초록 (Multilingual Abstract)

Brain herniation into the middle ear cavity is a rare entity that occurs mostly as a complication of otologic surgery. Other causes
include a congenital skull base defect, infection, trauma, neoplasm and irradiation. It gives rise to cerebrospinal fluid otorrhea, progressive
hearing loss, tinnitus, meningitis and other neurologic symptoms. Such patients tend to be misdiagnosed as having chronic
otitis media and are often treated for long periods with inadequate conservative therapy. We report a case of brain herniation into the
middle ear following traumatic temporal bone fracture, which was treated surgically via a transmastoid approach. (Korean J
