摘　　要：目的：研究人出生后前庭小管的发育，并探讨其临床意义。方法：对足月胎儿和正常成人前庭小管（各６块颞骨）行连续切片并进行计算机辅助的三维结构重建。结果：足月胎儿和正常成人前庭小管有明显的解剖差异。足月胎儿呈一近似直管形，成人呈倒“Ｊ”形。足月胎儿前庭小管外口径、内表面积、长度、容积明显较成人小，而二者的内口径相差不显著。足月胎儿前庭小管明显较成人小。前庭小管外口径可充分反映前庭小管的发育程度。结论：胎儿在出生后其前庭小管要经过充分发育方可达到正常成人的形状。如果前庭小管发育障碍则引起狭窄或阻塞。Objective:To study the postnatal development of human vestibular aqueduct(VA),and explore its clinic value.Methods:Computer assisted 3 dimensional image reconstruction was conducted on the serial section of human VA both neonate and normal adult(each 6 temporal bones).Results:There was significant difference in the anatomy of VA between neonate and normal adult.The VA of neonate was just like a straight tube while the adults′was similar to an inverted 'J' in shape.The diameter of external aperture,inner surface area,length and volume of VA of neonate was significantly smaller than that of adult.There was no significant difference in the diameter of inner aperture of VA between neonate and adult.The VA of neonate was significantly smaller than that of adult in size.The external aperture may reflect the development of VA.Conclusions:The full development changed VA from the shape of neonate to that of adult.VA will be narrowed or obliterated if it was maldevelopment
