作者们对生前无耳石损害的颞骨进行水平连续组织切片以了解耳石及其死后变化和人为变化,从而对耳石病变提出了若干见解。共观察76例117耳,年龄由0～81岁。标本先用10％的福尔马林固定后,经三氯醋酸脱钙,酒精脱水后用火棉胶包埋切成20μm厚,再经苏木精曙红染色后切片。组织学观察:耳石经苏木精蓝染,呈粒状或 The authors made horizontal and continuous histological sections of the temporal bone without otolith damage in order to understand the changes in otoliths and their postnatal changes and anthropogenic changes. A total of 76 cases were observed in 117 ears, aged from 0 to 81 years old. The specimens were fixed with 10% formalin, decalcified with trichloroacetic acid, dehydrated with alcohol, and then cut into 20 μm thick with collodion and stained with hematoxylin eosin. Histological observation: otolith blue stained with hematoxylin, was granular or
