We report 9 cases of aphasia following lesions in the region of the left frontal operculum. It is not possible to capture their variety of clinical manifestations with the simple labels of "Broca's area aphasia." or "Broca's area aphasia." Analysis of the breakdown of various components of speech and language in these cases suggests that the operculum, lower motor cortex, and subjacent subcortical and periventricular white matter contain critical parts of different language systems. These systems can be independently impaired. There are several common language syndromes that follow damage that includes the left frontal operculum. These syndromes reflect the effects of the direction and extent of the lesion in the various language systems.
我们报告了9例左侧额盖区病变后出现失语的病例。用“布罗卡区失语症”或“布罗卡区失语症”这些简单标签无法涵盖其多种多样的临床表现。对这些病例中言语和语言各个组成部分的分析表明，额盖、初级运动皮层以及其下方的皮质下和脑室周围白质包含不同语言系统的关键部分。这些系统可能会独立受损。有几种常见的语言综合征是由包括左侧额盖区在内的损伤引起的。这些综合征反映了病变在各种语言系统中的方向和范围所产生的影响。
