Applied anatomy of the frontal lobe-interverulare-choroid fissure approach to the third ventricle via neuroendoscopy
摘要
Abstract
Objective:To explore the exposed range and operable space of the third ventricle using the neuroendoscopic frontal lobe(F)-interverulare(I)-choroid fissure(C)approach(F-I-C approach),and to conduct a quantitative anatomical analysis.Methods:Six adult cadaveric heads fixed with 10%formaldehyde and infused with colored latex were included as surgical simulation specimens.For each specimen,a simulated operation was performed to expose the third ventricle via the F-I-C operative approach under bilateral 0° and 30° neuroendoscopy.The exposure angles and anatomic measurements of relevant important structures in the approach were observed.In addition,Photoshop CS6 scale was used to measure the distance between the medial walls of the two thalami as the inner and outer diameters of the surgical approach,the aqueduct-mamillary body spacing and the infundibular recess-papillary spacing as the anterior and posterior diameters,and the superior pineal recess-aqueduct spacing as the upper and lower diameters.The maximum visible area of the third ventricle was calculated and the operable angles from sagittal,coronal and longitudinal positions of the surgical approach were measured.The exposure and operability of the third ventricle via this approach were evaluated by using the classic third ventricle exposure and operability scale.Results:The inner and outer diameters of the F-I-C approach were 3.4-4.6(4.2±0.4)mm.The anteroposterior diameter was divided into two parts:aqueduct cerebri to mamillary body 16.8-18.5(17.6±0.5)mm,and infundibular recess to mamillary body 7.2-8.8(7.8±0.5)mm.The superior-inferior diameter was 7.0-9.0(7.8±0.8)mm.The exposure score of funnel recess was three.The sagittal area of the third ventricle exposed by F-I-C approach under 0° or 30° neuroendoscopy was(216±49)mm2,and the longitudinal operable angle was(16±3)°.The coronal area was(245±53)mm2 and the longitudinal operating angle was(19±3)°.Conclusion:The F-I-C approach under neuroendoscopy has good feasibility and operability for the exposure range of the anterior,middle and posterior parts of the third ventricle.关键词
