Anatomical study of the approach through interhemispheric fissure - corpus callosum septum - the third ventricle under the multimodal assistance
Objective To study the anatomical approach of interhemispheric fissure-corpus callosum septum -third ventricle guided by navigation，and explore the method of neuronavigation in optimizing the approach and its application value. Methods 5 adult cadaveric heads were selected, and to simulate the interhemispheric fissure - corpus callosum septum - the third approach. The relevant structures in the approach pathway were observed under neuronavigation, neuroendoscope and microscopy. The corresponding data were measured and statistically analyzed. Results Through the 5 cases of specimen anatomical data and navigation measurement data for statistical analysis, it was found that the P values are greater than 0.05, indicating that the entity from measured data and navigation data had no statistical difference, it also shows that the neuronavigation can guide the approach accurately. Conclusions Under the guidance of navigation precise incision of the corpus callosum reliable and precise recognition of septum pellucidum and fornix important anatomic structures, optimization of the previous approach could be achieved so that brain injury could be reduced and operation reliability augmented.
