耳蜗导水管是连接鼓阶与蛛网膜下腔的导管。对此管的研究已有300年历史,首由Verney(1684年)发现,但至今仍有许多问题待解决。本研究取50只豚鼠将生理盐水、印度墨及金黄色葡萄球菌注入小脑延髓池,金黄色葡萄球菌也注入鼓阶。以生理盐水、2%戊二醛作心脏灌注,切除颞骨,用戊二醛和四氧化锇双重固定,制成断面标本,用光显微镜和扫描电镜观察耳蜗 The cochlear aqueduct is the conduit connecting the scaphoid to the subarachnoid space. The study of this tube has been 300 years, first discovered by Verney (1684), but there are still many problems to be solved. In this study, 50 guinea pigs were injected with normal saline, Indian ink and Staphylococcus aureus into cerebellar cistern, and Staphylococcus aureus was injected into the scala tympani. With saline, 2% glutaraldehyde for cardiac perfusion, resection of the temporal bone, with glutaraldehyde and osmium tetroxide dual fixation, made of cross-section specimens, light microscopy and scanning electron microscopy of the cochlea
