眶额区位于双侧额叶下方前颅凹中,嗅束将直回与其他脑回分开。眶额区本身在各脑回间,以及与额叶凸面及内侧面,颞叶有广泛的联系。眶额区起源的癫痫少见。发作开始均先出现动作停止、无反应及茫然,而后根据扩布的不同出现:嗅觉异常、过度运动、头眼偏向同侧或对侧、重复动作等运动症状、自主神经症状,还可以有难以确定的感觉异常、发笑、似曾相识、视幻觉、自动症。根据临床症状可以分为额叶型、颞叶型及额颞叶型。头皮脑电图很难提供有定位价值的异常,常为额颞叶甚至双侧额颞叶异常。深部电极尤其是立体脑电图有定侧定位价值。眶额区癫痫几乎均为药物难治性癫痫,应以外科治疗为主。
The orbital frontal area is located in the anterior cranial fossa below the bilateral frontal lobes, and the olfactory tract separates straight back from the rest of the brain. Orbital frontal area itself in each brain back, as well as with the frontal and medial frontal, temporal lobe has extensive contact. Orbitofrontal origin of epilepsy rare. At the beginning of the episode, the movement stops, the reaction does not occur, and the loss occurs. According to the different occurrences of the expansion, abnormalities of sense of smell, over-exercise, head-to-side or contralateral, repetitive motor symptoms and autonomic symptoms can also be difficult Determined to feel abnormalities, laughter, deja vu, visual hallucination, autism. According to clinical symptoms can be divided into frontal, temporal lobe and frontotemporal lobe. Scalp EEG is difficult to provide an anomalous positioning value, often amount of frontotemporal or bilateral frontotemporal anomaly. Deep electrodes, especially stereoscopic electroencephalography has a fixed side positioning value. Orbital frontal epilepsy are almost drug-refractory epilepsy, surgical treatment should be based.
