The morphology of the minor fissure, i.e., the shape of the upper surface of the middle lobe, was studied in 10 specimens and in 60 thoracic CT's. In 8 specimens and 54 CT's there was the arrangement typical for the right lung consisting of 3 distinct lobes. The upper surface of the middle lobe had a convex upward shape against the base of the upper lobe in all anatomical preparations and in 52 of the CT's. The position and shape of the convexity was, however, quite variable. In 2 cases the upper surface of the middle lobe was flat. In 78% the minor fissure was incomplete and in 2 cases it was absent.
在10个标本和60例胸部CT中研究了小裂的形态，即中叶上表面的形状。在8个标本和54例CT中，呈现典型的右肺由3个不同叶组成的形态。在所有解剖标本以及52例CT中，中叶上表面相对于上叶基部呈向上凸起形状。然而，凸起的位置和形状变化很大。有2例中叶上表面是平的。78%的小裂不完整，2例不存在小裂。
