蝶枕角与颅底诸结构至耳眼平面垂直距离的纵向比较

目的:为人颅底的生长发育研究提供正常的颅底结构测量数据和参照标准;初步分析颅底生长发育趋势和特点。方法:对人不同生长发育阶段颅底标本诸结构进行观察和测量,并对其进行相互比较和纵向分析。结果:颅底在不同发育阶段各有其趋势和特点,蝶枕角随着年龄的增长逐渐变小,但性别之间无差异,颅前窝诸结构变化幅度最大,颅中窝的变化相对最小,11项测量指标在不同生长发育阶段的变化各异。结论:观察测量数据可为人颅底生长发育进一步研究提供依据,蝶枕角、耳眼(FH)平面可作为颅底生长发育的观察测量指标和参照平面。

Comparison between perpendicular distances from spheno-occipital angle or cranial base structures to Frankfort horizontal plane

Objective:To provide normally measured database and reference standard of growth and developmental mechanism of cranial base in human being as well as to analyze the characteristics involved in growth and development of cranial base preliminarily.Methods:The specimen of skull bases in different ages was observed,and the intercom- parison between them was implemented.Results:The skull bases had their own diversity in various developmental stage.The spheno-occipital angle was shrinking with the increasing of age,yet there was no gender discrepancy;and great changes were found in the structures of anterior cranial fossa,while there were minimum changes in middle crani- al fossa.All these above could be observed by 11 measuring index.Conclusion:The measured data involved in the growth and developmental mechanism of skull base may be as reference for further study;and the spheno-occipital angle or frankfort horizontal plane may he as the measurement reference of growth and development of the skull base.
