Results Anatomic measurements showed vadian canal was located behind the sphenoid-palatine hole, and its external orifice was shaped as infundibular. The vertical dianseter was (3.5±0.9) torn and the horizontal diameter was (2.9±0.5) mm.

The marginal division was a flat fan-shaped structure with a volume of (0.48±0.02) mm3, a maximum rostral-caudate axis of 1.6 mm, a maximum dorsal-ventral axis of 2.158 mm, and a widest axis (the diameter at lateral-medial coronal brain section) of 0.17 mm. The marginal division also moved progressively externally from the rostral section to the caudate section, but its scope was larger than that of others. The whole marginal division changed evenly from the rostral section to the caudate one. Its flat structure widened progressively and its dorsal-ventral diameter narrowed gradually and became plate-shaped.

The distances between inferior margin of 12th rib and the 3 above-mentioned nerves were all measured. Results: The superior lumbar triangle was quadrilateral (55%), triangular (35%) or irregular (5%). If the 12th rib was too short, the upper border of the triangle would be the 11th rib (5%). Four grouping patterns of the 3 nerves were found in front of the triangle, and the average distance between inferior margin of 12th rib and the 3 nerves was (16.92±6.32)mm,(59.49±14.97)mm and (112.49±17.15)mm, respectively.
