喉骨架的几何测量是喉研究，特别是生物力学建模的基础。传统上，犬喉被用作人类喉的模型，因为它们在大小和总体结构上的相似性，但由于在美国用于研究的犬物种的可用性越来越少，因此继续寻找替代模型。在这份报告中，提出了一种定义和标记喉框架参数的修订方法。测量了绵羊的喉软骨，并将测量结果与文献中先前报道的人类和犬软骨的测量结果进行比较。绵羊环状软骨、甲状腺软骨和杓状软骨与人和犬软骨有显著差异。此外，真假声带之间缺乏明确的边界，这表明绵羊模型可能并不总是适合与人类喉的发音进行直接比较。
Geometric measurement of the laryngeal skeleton is a fundamental step in laryngeal studies, especially in biomechanical modeling. Traditionally, canine larynges have been used as models of the human larynx because of their similarity in size and gross structure, but the search continues for an alternative model because of the diminishing availability of the canine species for research in the United States. In this report, a revised method for defining and labeling laryngeal framework parameters is proposed. Ovine laryngeal cartilages were measured, and the measurements were compared to those of human and canine cartilages previously reported in the literature. The ovine cricoid, thyroid, and arytenoid cartilages were significantly different from the human and canine cartilages. Also, the lack of a definite border between the true and false vocal folds revealed that the ovine model may not always be suitable for a direct comparison to the human larynx in phonation.
