Seizure onset pattern (SOP) represents an alteration of electroencephalography (EEG) morphology at the beginning of seizure activity in epilepsy. With stereotactic electroencephalography (SEEG), a method for intracranial EEG evaluation, many morphological SOP classifications have been reported without established consensus. These inconsistent classifications with ambiguous terminology present difficulties to communication among epileptologists. We reviewed SOP in SEEG by searching the PubMed database. Reported morphological classifications and the ambiguous terminology used were collected. After thoroughly reviewing all reports, we reconsidered the definitions of these terms and explored a more consistent and simpler morphological SOP classification. Of the 536 studies initially found, 14 studies were finally included after screening and excluding irrelevant studies. We reconsidered the definitions of EEG onset, period for determining type of SOP, core electrode and other terms in SEEG. We proposed a more consistent and simpler morphological SOP classification comprising five major types with two special subtypes. A scoping review of SOP in SEEG was performed. Our classification may be suitable for describing SOP morphology.

SEEG 中癫痫发作模式的范围审查和形态学分类的建议

癫痫发作模式（SOP）代表癫痫发作活动开始时脑电图（EEG）形态的改变。立体定向脑电图（SEEG）是一种颅内脑电图评估方法，已报道了许多形态学 SOP 分类，但尚未达成共识。这些不一致的分类和模糊的术语给癫痫病学家之间的沟通带来了困难。我们通过搜索 PubMed 数据库审查了 SEEG 中的 SOP。收集了报告的形态学分类和使用的模糊术语。在彻底审查所有报告后，我们重新考虑了这些术语的定义，并探索了更一致、更简单的形态学 SOP 分类。在最初发现的536项研究中，经过筛选和排除无关研究后最终纳入14项研究。我们重新考虑了 EEG 起始时间、确定 SOP 类型的周期、核心电极和 SEEG 中其他术语的定义。我们提出了一种更一致、更简单的形态学 SOP 分类，包括五个主要类型和两个特殊亚型。对 SEEG 中的 SOP 进行了范围审查。我们的分类可能适合描述 SOP 形态。
