A RARE COMPLICATION AFTER REPAIRING TEMPORAL LOBE HERNIATION INTO MASTOID CAVITY: NON-CONVULSIVE STATUS EPILEPTICUS

The aim of this study is to present the case of an 18-year-old male who developed non-convulsive status epilepticus (NCSE) after the operation for temporal lobe herniation. The herniation of meningeal and brain tissues into the middle ear and mastoid cavity is a rare and potentially life-threatening condition. Temporal lobe herniation might occur after otologic surgeries which are often related with an iatrogenic bony defect of tegmen tympani. NCSE can be defined as prolonged seizure activity and is an extremely rare complication of otological surgeries. To our knowledge, this is the first case for NCSE which developed after otologic surgery in the literature.
