The angle between the annulus fibrocartilaginous and the superior crest of the petrous bone was measured with 14 (10 to 19) degrees. The height of the annulus was in our material 10.04 mm, the width 9.45 mm. Measured were also the length of the plicae malleares and the height of the recessus membrane tympani anterior, posterior et superior with (2.5, 3.0 and 1.5 mm). In about 74%, the chorda tympani was imbedded in different zones of the plicae malleares. Its entrance and exit areas, the length of its intratympanal course and its width were measured. Included are also values of the ligaments of the otic ossicles, measurements of the ostium tympanicum tubae auditivae, of the epitympanic recess, the aditus ad antrum, and the antrum mastoideum. The eminentia pyramidalis, the sinus posterior and the sinus tympani, ponticuli and subicula, the fossula fenestrae cochleae and the fenestra cochleae, the fenestra vestibuli and prominences of the facial canal in the lateral semicircular canal have been researched and measured. Also the tympanic nerve and its course on the promontorium have been estimated.
纤维环与颞骨岩部上嵴之间的夹角经测量为14（10至19）度。在我们的材料中，纤维环的高度为10.04毫米，宽度为9.45毫米。还测量了锤襞的长度以及鼓膜前、后和上隐窝的高度（分别为2.5、3.0和1.5毫米）。约74%的情况下，鼓索嵌入锤襞的不同区域。测量了其进出区域、鼓室内行程的长度及其宽度。还包括听小骨韧带的值、咽鼓管鼓口、上鼓室隐窝、鼓窦入口和乳突窦的测量值。对锥隆起、后窦和鼓室窦、小丘和下丘、蜗窗凹和蜗窗、前庭窗以及外侧半规管内面神经管的隆起进行了研究和测量。还评估了鼓室神经及其在岬部的行程。
