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,额窦和蝶窦的最初气化时间要迟于上颌窦和筛窦.
Objective: To provide anatomical basis for the best age of imaging diagnosis and paranasal sinus surgery.Methods: 29 Chinese nationals from three age groups were divided into three groups according to equal proportions: sagittal section And coronal section.Results: The maxillary sinus and ethmoid sinus were obvious in each group.No obvious frontal sinus and sphenoid sinus were found in the infant group, and there was no obvious frontal sinus and ethmoid sinus in 50% of the age group Sinus and sphenoid sinus.The long axis of adult maxillary sinus was horizontal and the opening of maxillary sinus in children was obliquely downward-oriented.Conclusion: The morphology of paranasal sinuses has obvious age change, the initial gas of frontal sinus and sphenoid sinus The time is later than the maxillary sinus and ethmoid sinus.
