Abstract
Mortality from intacranial complication has recently decreased in comparison with the preantibiotic era. This reduction in mortality is due to the continuing introduction of new and effective antibiotics, advances in imaging technology and improvements in both patient care and surgical techniques. In particular, recent progress in magnetic resonance imaging has now made it possible to obtain detailed images of the inner ear and intracranial focus lesions. We herein report 2 cases of otogenic intracranial complications. In case 1, a 52-year-old man was admitted to our hospital after complaining of abrupt and left otorrhoe symptoms. He was diagnosed as having acute meningitis secondary to cholesteatoma. A fistula was present at the lateral semicircular canal by mastoidectomy. He was cured by intravenous antibiotic therapy and the removal of the cholesteatoma. In case 2, a 50-year-old woman was admitted with a diagnosed of a temporal lobe abscess of otogenic origin based on the evaluation of another physician. A cerebral herniation occurred twice after her admission. The administration of both antibiotics in massive doses and glyceol, as well as the drainage of cerebral spinal fluid by a neurosurgeon, successfully resulted in the progressive reduction in the size of the abscess.
