Studies about the use of sheep in surgical training and experimental otologic surgery are rare. This study intends to contribute to the knowledge on this field.
To study sheep inner ear structures using computerized tomography and serial cross-sections to collect more accurate morphometric data to compare sheep and human ears.
This descriptive study compared the inner structures of sheep and human ears. Measurements were made using computerized tomography, and they were stored in a DICOM compact disc for later analysis and manipulation, with a program used for medical image analysis (Osíris 4.16).
Mean measures for sheep and human ears were found to be similar in this morphological study. Most structures (10 out of 15) maintained the 2/3 ratio of sheep to human ear.
The results of this morphometric study of sheep ear are an important contribution to the development of an animal model to be used for surgical training and experimental otologic surgeries.
关于在外科手术训练和实验性耳科手术中使用绵羊的研究很少。本研究旨在增进对该领域的了解。
利用计算机断层扫描和连续横断面研究绵羊内耳结构，以收集更准确的形态学数据，用于比较绵羊和人类的耳朵。
本描述性研究比较了绵羊和人类耳朵的内部结构。使用计算机断层扫描进行测量，并将其存储在DICOM光盘中，以便日后分析和处理，使用了一个用于医学图像分析的程序（Osíris 4.16）。
在这项形态学研究中，发现绵羊和人类耳朵的平均测量值相似。大多数结构（15个中的10个）保持了绵羊与人类耳朵2/3的比例。
这项绵羊耳朵形态学研究的结果对开发用于外科手术训练和实验性耳科手术的动物模型具有重要意义。
