Transseptumpellucidumrostrostomy: anatomical considerations and neuroendoscopic approach
PURPOSE: Verify the presence of the rostral lamina of the corpus callosum, and set parameters for neuroendoscopy. METHODS: Relationship of the floor of the frontal horn of lateral ventricle and the hypothalamic-septal region were studied after sagittal and axial sections of the brains. Measurements were compared using F and Student t tests. The correlations between anterior-posterior diameter of the interventricular foramen / anterior-posterior diameter of the fornix column, and between anterior-posterior diameter of the interventricular foramen / length of the rostral lamina were performed by Pearson index test. RESULTS: There was no statistically significant difference in measurements performed in both hemispheres (p<0.05). Positive correlations were observed between the anterior-posterior diameter of the interventricular foramen / anterior-posterior diameter of the fornix column (R = 0.35), and between the anterior-posterior diameter of the interventricular foramen / length of the rostral lamina (R = 0.23). CONCLUSION: Rostral lamina was observed in all brains. It was possible to perform an endoscopic fenestration in the rostral lamina, communicating safely the lateral ventricle with a polygonal subcallosal cistern.
