Sažetak
In our experiments we used human fetal skulls from collection called “Mini skull collection”. Recent measurements were performed to determinate the fetal development dynamic of auditory ossicles and bony part of visual system. Anatomy of ossicles in adults was described in different studies, but there are only few data available about ear bones dimensions during fetal life. The orbital apex is a congested area and surgeons should have an exact concept of the relations and sizes of each structure, as well as possible variations. For a better understanding of those structures in adults, it is crucial to investigate their fetal evolution. We used previously macerated 30 ossicles, 12 frontal and sphenoid bones. Bones were scanned by microCT and bone volume analysis was performed by CTAn software. Bones were in both experiments divided in three groups based on fetus length: 300, 400, and 500mm. Average incus and malleus bone volume in all groups was increased in accordance with the fetal linear growth. Average stapes bone volume in 500mm fetus showed a dynamic growth, while in other two groups was no significant change. The development of both optic canal and orbit varies during fetal period. The ratio of those diameters in different time periods is significant and shows that the orbit grows faster in the earlier fetal period, while the optic canal enlarges later. Both diameters are in better correlation with fetus length than its weight.
