Structural characteristics of human incudostapedial articulation (ISA) have been studied on a series of histological sections from temporal bone decalcified pyramids in three planes and by means of macro-micropreparation of tympanal structural elements from 96 human fetuses at various terms of gestation. It was established that the surface of the lenticular process has a spherical form. Its length surpasses its width. The articular surface on the head of the stapes presents a dome-shaped lacuna. The capsule is usually thicker in its posterior part than in the anterior one. It can endure deviation of the long lenticular process up to 3 mm without rupture. When the deviation overruns 3.5 mm, the articular bursa and round ligament of the base of the stapes break. This property of the capsule should be kept in mind when operating on the stapes.
通过对96例不同孕周人类胎儿颞骨脱钙锥体的三个平面的一系列组织学切片以及通过对鼓室结构元件进行宏观 - 微观制备,研究了人类砧镫关节(ISA)的结构特征。结果表明,豆状突的表面呈球形。其长度超过宽度。镫骨头的关节面有一个穹顶状的腔隙。关节囊通常后部比前部厚。它能够承受豆状突长达3毫米的偏移而不破裂。当偏移超过3.5毫米时,镫骨底的关节囊和圆韧带会断裂。在进行镫骨手术时应牢记关节囊的这一特性。
