日本从1955年以后,临床开始报告耳硬化症,但直到1968年中村才首次报告经病理组织学证实的与白人相同的日本人耳硬化症病变,1971年坂井初次发现1例生前无听力下降的57岁女尸的颞骨为组织学的耳硬化症,以后有关报告即逐渐增加。耳硬化症的病理变化仅特异地发生于骨迷路囊内,因而为了充分理解其病理改变,应复习骨迷路囊的胚胎学及组织学特点。
Japan began to report otosclerosis clinically after 1955. However, it was not until 1968 that Nakamura first reported the same pathological changes of otosclerosis in Japanese as that of whites in 1968. In 1971, Sakai first discovered that one case had no hearing loss before birth 57-year-old female corpse temporal bone histological otosclerosis, the relevant reports that is gradually increased. Pathological changes in otosclerosis occur only specifically in the bony labyrinth, so in order to fully understand the pathological changes, we should review the embryonic and histological characteristics of bony labyrinth.
