It is important to know the morphometry of the auditory ossicles for middle ear surgical applications. The present study aims to investigate the morphometric measurements of sheep auditory ossicles and the relationship between these ossicles. In this study, 100 malleus, incus and stapes of 50 Akkaraman sheep were examined using at trinocular stereo microscope and a total of 19 morphometric measurements were taken. The mean values of the morphometric measurements were obtained, and correlation analysis was performed between each part of each auditory ossicle. Similarities were found between the measurements of the lengths of the malleus, manubrium mallei and incus, and the width of the base of the stapes with morphometric measurements in human auditory ossicles. A significant positive correlation was found between the length of the malleus with the length of the manubrium mallei, between the length of the incus with the lengths of the long crus and corpus incudis, between the length of the stapes with the lengths of the rostral crus, caudal crus, caput stapedis, and the length and width of the intercrural foramen. Due to the anatomic similarities between sheep and human auditory ossicles, it was concluded that the auditory ossicles of sheep are suitable for use in the training of human ear surgery applications.
了解中耳外科应用中听小骨的形态学非常重要。本研究旨在研究绵羊听小骨的形态学测量值及其各部分之间的关系。在这项研究中，使用三目立体显微镜检查了 50 只阿克卡曼羊的 100 个锤骨、砧骨和镫骨，共进行了 19 项形态学测量。获得了形态学测量值的平均值，并对每个听小骨的各部分之间进行了相关分析。在绵羊听小骨的测量值与人类听小骨的锤骨、锤骨柄和砧骨长度，以及镫骨底宽之间发现了相似之处。在锤骨的长度与锤骨柄的长度之间、砧骨的长度与长脚和体部的长度之间、镫骨的长度与前脚、后脚、镫骨顶和两脚之间的孔的长度和宽度之间发现了显著的正相关。由于绵羊和人类听小骨的解剖结构相似，因此可以得出结论，绵羊的听小骨适合用于人类耳部手术应用的培训。
