鼓室颈静脉壁的胚胎发育及其临床解剖学的研究

DEVELOPMENT OF THE TYMPANIC JUGULAR AND ITS CLINICAL ANATOMY

本文取正常胎儿和生后颞骨210个,用组织切片方法,光镜观察鼓室颈静脉壁的胚胎发育及颈静脉球位置。颈静脉壁在胚胎24周形成。生后颈静脉窝高于鼓环者占64.8%,其中55.2%颈静脉窝向内侧高拱到鼓室底内侧,9.6%凸入下鼓室外侧。鼓室颈静脉骨壁骨质缺损者占25.6%。

The relationship between the bottom of the hypotympanon and the jugular bulb has been investigated on the basis of a histological analysis of 210 temporal bones ranging from 12-week-old to adult.According to the growth and the position of the tympanic jugular wall,the development law of tympanic jugular wall and dehiscent bone wall and its clinical significance are discussed.
