To describe the morphological and topographic features of the triangular recess (TR) in the anterior wall of the third ventricle and the pathological conditions that allow its observation during ventricular endoscopic neuronavigation.
A systematic review of records and operative videotapes for 145 patients who underwent endoscopic third ventriculostomy was performed.
The TR could be recognized in five cases of hydrocephalus, each caused by a different underlying pathological condition. The approach was precoronal in four cases and suboccipital in one. The morphological and topographic features of the TR and adjacent structures varied among the different cases.
Although it is seldom reported in neuroanatomy handbooks and is not readily accessible under normal conditions, the TR is a characteristic structure of the third ventricle, which might become apparent in several conditions that produce hydrocephalus. Neurosurgeons who perform neuroendoscopy should be aware of this structure and of the situations that cause its deformation and allow its observation during endoscopic neuronavigation.
描述第三脑室前壁三角隐窝（TR）的形态和位置特征，以及在脑室内镜神经导航过程中能够观察到该隐窝的病理情况。
对145例行内镜下第三脑室造瘘术患者的病历记录和手术录像进行系统回顾。
在5例脑积水患者中可识别出TR，每例由不同的潜在病理状况引起。4例采用冠状缝前入路，1例采用枕下入路。不同病例中TR及相邻结构的形态和位置特征各不相同。
尽管TR在神经解剖学手册中鲜有报道，在正常情况下也不易观察到，但它是第三脑室的一个特征性结构，在几种导致脑积水的情况下可能会显现出来。进行神经内镜手术的神经外科医生应了解该结构以及导致其变形并在内镜神经导航过程中能够观察到它的情况。
