Morphological Study of Surgical Approach by Superior Temporal Sulcus-Temporal Horn of Lateral Ventricle Approach Using Volume Rendering

Abstract

In this research, we acquired the length of the superior temporal sulcus, the shortest distance from the superior temporal sulcus to the temporal horn of the lateral ventricle, and the approach angle between the median sagittal plane and the shortest segment from the superior temporal sulcus to the temporal horn of the lateral ventricle measuring 98 specimens by magnetic resonance imaging volume rendering. At the same time, we preliminarily oriented the point of the superior temporal sulcus, which is closest to the temporal horn of the lateral ventricle, aimed at finding out the best entrance point of surgical approach through the superior temporal sulcus to the temporal horn of the lateral ventricle and reducing the damage to optic radiation as well as other nerve fibers during the operation. The results indicate that the point at the front side 3/5 of the superior temporal sulcus may be the ideal surgical approach entrance point, and there is no difference between 2 cerebral hemispheres (P < 0.05).
