Study on microsurgical anatomy and related approaches of apex of basilar artery
Objective To study the neurosurgical microanatomy of approaches to the apex of the basilar artery to evaluate their exposure range. Methods 10 cranial cadaver (20 sides) were researched in simulative neurosurgical approaches. Petrional approach, subtemporal transtentorial approach and presigmoid approach were used to observe the apex of basilar artery, and the exposure range of the three approaches was compared. Their exposure range was evaluated subjectively. Results The minimum exposure distance of the petrional approach, the subtemporal transtentorial approach, the presigmoid approach was (63.85±2.54)mm, (66.58±2.03)mm，(66.01±1.41)mm, respectively. Exposure distance of the petrional approach was shortest, there was no statistic difference in the subjective scorings of the three approaches. Conclusion The best exposure approach of the apex of basilar artery is the pterional approach.
