Abstract:
Objective To investigate the incidence of various grade of posttraumatic epilepsy in different time and risk factors by analyzing cerebral trauma cases of civil pilots and correlative literatures.The conclusion is expected to contribute to the aviation medical assessment for the civil pilot with posttraumatic epilepsy. Methods For analyzing epidemiology studies of posttraumatic epilepsy 9475 cases of civilians' posttraumatic epilepsy (include 605 severe, 1955 moderate and 6915 mild traumatic brain injury cases) were reviewed. Besides, 2 epilepsy cases of civil pilots with severe traumatic brain injury, who were specially applied for assessment, were also analyzed to investigate the application in aeromedical assessment. Results ①The severer traumatic brain injury the higher incidence of posttraumatic epilepsy. ②The possibility of posttraumatic epilepsy seizure was gradully diminished with time. The incidence of posttraumatic epilepsy could reduce to lower than 1% after 1, 3 or 8 years corresponding to the mild,moderate and severe traumatic brain injury. ③ The high risk factors of posttraumatic epilepsy included brain contusion, subdural hematoma, depressed fracture, loss of consciousness or post traumatic amnesia more than 24 h and early seizure. The close follow-up showed that 2 pilots well recovered by timely treatment and no more abnormities and seizure happened. One pilot was permitted for co-piloting at the 4th year of injury and had no epilepsy seizure in his safe flying for 2 years (1800 h). Another pilot returned to his qualified flight at the 9th year and had safely flied as pilot instructor for 4 years ( 1600 h) without seizure.Conclusions By applying 1% rule in aeromedical assessment, the mild traumatic brain injured pilot would be suggested to fit for flying by 1-year recovery and 3-year recovery for the moderate if no more abnormities were diagnosed. For the severe injured pilot, the flying qualification could be considered with or without limitation by 8-year recovery.
