Abstract：Objective To compare microanatomical features of surgery via pterional approach versus subtemporal approach for amygdala resection based on virtual reality image model. Methods Imaging data of 15 adult cadaver heads (30 sides) was inputted into virtual reality system to establish three-dimensional anatomical model of the temporal lobe and surrounding structures. Transpterional approach and subtemporal approach exposing amygdala were simulated by drawing cylinder. Anatomical exposures were observed, measured and compared following change of surgical trajectory. Results The volumes of brain, middle cerebral artery, sphenoparietal sinus via pterional approach were exposed at the anterior edge of amygdala more than at the posterior edge, but the volume of the route exposure was less at the anterior edge than at the posterior edge. The volumes of the route and brain had more exposure at the anterior edge of the amygdala than at the posterior edge in subtemporal approach, while the volumes of the route and brain had more exposure via pterional approach than via subtemporal approach for the anterior and posterior edges of the amygdala. The differences of above items reached statistical significance (all P<0.05). Conclusions Virtual reality three-dimensional image model helps to compare surgical exposures and invasions quantitatively between different approaches in exposing amygdala, and provides information for guiding minimally invasive surgery.
