Pathomorphological investigations of the cholesterol crystals were carried out in the middle ear effusions and cholesterol granulomas of experimented animals and humans. The shape and size of the cholesterol crystals were variable, depending upon the surrounding substances. In the middle ear effusions, the crystals formed rather large rectangular structures, which tended to become smaller and thinner, as the granulomas developed. In the compact granulomas, the crystals appeared smaller, thinner and deformed, suggesting that they may possible be dissolved by a phagocytosis of active giant cells.
对实验动物和人类的中耳积液及胆固醇肉芽肿中的胆固醇晶体进行了病理形态学研究。胆固醇晶体的形状和大小各不相同，这取决于周围的物质。在中耳积液中，晶体形成相当大的矩形结构，随着肉芽肿的发展，这些结构往往会变得更小、更薄。在致密的肉芽肿中，晶体显得更小、更薄且变形，这表明它们可能会被活跃的巨噬细胞吞噬而溶解。
