Stereo depth electroencephalography (EEG) is of proven benefit in lateralizing and localizing seizure origin in select cases of epilepsy. There are potential hazards and technical considerations inherent with depth EEG, however, that have limited the general applicability of this technique. A new depth EEG electrode with materials and design features that facilitate safe insertion and artifact-free recording has been developed. The design features and technique for inserting the electrode are described. The electrode was evaluated during 2600 hours of implantation and recording in seven patients. With the use of stereotactic techniques, the electrode could be positioned accurately within precise anatomical landmarks such as the amygdaloid nucleus and the hippocampus. After insertion, no hemorrhage or edema was detected along the electrode tracts by third generation computed tomographic scanning. There was no evidence of pyrogenicity or infection. Electrode migration was not observed. A large electrical field could be sampled because of the relatively large surface of the cylindrical depth electrode contacts.
立体深度脑电图（EEG）在某些癫痫病例中确定癫痫发作起源的侧别和位置方面已被证明具有益处。然而，深度脑电图存在一些潜在风险和技术考量，这限制了该技术的广泛应用。一种具有便于安全插入和无伪迹记录的材料及设计特点的新型深度脑电图电极已被研发出来。本文描述了该电极的设计特点及插入技术。在7名患者中进行了2600小时的植入和记录过程中对该电极进行了评估。使用立体定向技术，电极能够精确地放置在诸如杏仁核和海马体等精确的解剖标志内。插入后，通过第三代计算机断层扫描未在电极通道沿线检测到出血或水肿。没有发热或感染的迹象。未观察到电极移位。由于圆柱形深度电极触点的相对较大表面，可以采集到较大的电场。
