鼻旁窦的年龄断面解剖学研究

目的：为影像学诊断和鼻旁窦手术的最佳年龄提供解剖学依据。方法：采用三组年龄的国人头部标本２９例，各组标本均按等比例分别切割为横切面、矢状切面和冠状切面。结果：各组标本均可见明显的上颌窦和筛窦；幼儿组未见显著的额窦和蝶窦。学龄组５０％未见明显的额窦和筛窦，余组标本可见额窦和蝶窦。成人上颌窦开口的长轴呈水平状，儿童上颌窦开口为向外下方的斜形管道。结论：鼻旁窦的形态有明显的年龄变化，窦额窦和蝶窦的最初气

SECTIONAL ANATOMY OF PARANASAL SINUSES RELATED TO AGE

Twenty-nine Chinese head specimens were used to explore the appropriate age for radiology and paranasal sinus surgery. The specimens were devided into three groups: the infant group, the school-age group and the adult group. The specimens were sawed into horizontal, sagittal and conoral sections. The results were as follows: The maxillary and ethmoid sinuses were found in the specimens of all three groups. The frontal and sphenoid sinuses were found in the adult group and in 50 percent of specimens in the school-age group, but not in the infant group, the maxillary ostium was found at the junction of the medial maxillary wall and the floor of the orbit, forming a tunned obliquely in adults. It is concluded that the shape of the paranasal sinuses change with age, and that the initial pneumatization of the frontal and sphenoid sinuses are formed later than the maxillary and ethmoid sinuses.
