【Objective】 To investigate the clinical significance of the EEG onset types for the localization of temporal lobe epilepsy.【Methods】 A total of 273 video-electroencephalogram recordings from 52 patients who were diagnosed with temporal lobe epilepsy. Patients were estimated by long-term video electroencephalogram and magnetic resonance image

and received surgeries

were retrospectively analyzed. All patients with electrocorticogram performed during surgery to localizing epileptic foci. And whose surgical results proved to be Engel class 1 for more than one year after the surgery were enrolled. According to the MRI results

52 patients were divided into Hippocampal sclerosis group

Non-Hippocampal sclerosis group. 【Results】 The localization of temporal lobe epilepsy can be correctly localized on 64% of tested patients

especially for the patients with hippocampal sclerosis. θ and δ rhythms onsets are the most common onset types of temporal lobe epilepsy. 【Conclusion】 The EEG onset types may have a potential localization diagnosis value in different pathologic temporal lobe epilepsy.
