胎儿听骨的应用解剖学及骨化进程的研究

THE RESEARCH ON THE ANATOMY OF EMBRYONIC AUDITORY OSSICLES AND THE OSSICIFICATION PROCESS

本研究解剖3～9个月流产死胎儿105具,自210耳取完整听骨615块,做了18项测量,并观察了鼓环的发生及形成,听骨各月龄的形态大小、长度、鼓室内变化及听骨骨化进程。

The rsearch on genesis of tympanic ring and tympanums and eardrums of embryos are made in this thesis. We have observed shapes and sizes of auditory ossicles with various months and the oisification from the experiment of having dissected 105 abortion embryos, which are 3-9 month old, and 18 item surveys of 61.5 pieces auditory ossicles from 210 side-ears. And the new discovery of tympanums variation is made. We have defined the ossification process of auditory ossicles by the detailed observation on evacuation in tympanums as well as the forming time and the changes of tympanic ring. This would be a reference to the hearing theory of embryos and new-born babies.
