Due to the establishment in recent years of neuroendoscopic third ventriculostomy (ETV), it has become possible during ETV to observe the ventral brainstem surface--particularly the prepontine cistern--in a minimally invasive manner via the third ventricular base with a neuroendoscope. As an adaptation of that technique in this study, we investigated a neuroendoscopic trans-third ventricle approach (ETTVA), which accesses lesions of the ventral brainstem surface with a neuroendoscope inserted via the stoma of the third ventricular floor. Our study included 6 cases, including one case each of neurenteric cyst, chordoma, pontine glioma (astrocytoma), ecchordosis physaliphora, endodermal cyst, and cystic schwannoma. Surgical operations performed by ETTVA included 3 cases of tumor resection, 2 cases of tumor biopsy, and 1 case of cyst puncture and aspiration. There were no complications accompanying ETTVA. Out of the 6 cases, only 1 required additional surgical treatment following ETTVA surgery. In the other 5 cases, no additional surgical procedures were performed. This study showed that ETTVA allowed access to the prepontine cistern quickly and in a minimally invasive manner. In selected cases, ETTVA can offer a new approach to these lesions.
