Retrospective observation of computed tomographic images to describe an anatomical difference in the shape of the pterygoid bone in French bulldogs (FB) and determine its prevalence and effect on the cross-sectional area of the airway, in comparison with normal conformation in brachycephalic and mesocephalic dogs.
Computed tomographic studies of FB and cocker spaniels (CS) that underwent examination of the head were reviewed. The shape and cross-sectional area of the pterygoid bone was recorded and compared between groups.
Thirty-six CS and 34 FB were included. In 79.41% (27/34) of FB, there was an abnormal shape of the pterygoid bone in comparison with all 36 CS, which had a normal shape of the pterygoid bone. Only 20.58% (7/24) of FB had a normal shape. The cross-sectional area of the airway at the level of the pterygoid bone for FB was 88.78 mm. The area was larger in FB with normal shape (average: 95.70 mm, SD ± 15.98) than those with abnormal shape (average: 86.98 mm, SD ± 20.32), though this difference was not statistically significant ( > 0.05). Cocker spaniels had a larger airway cross-sectional area than dogs in both FB groups, with a mean of 142.28 mm (± 24.87) and < 0.05.
French bulldogs frequently have an abnormal conformation of the pterygoid bone. This study identified further anatomical factors that might contribute to upper-airway obstruction in brachycephalic dogs.
回顾性观察 CT 图像，描述法国斗牛犬（FB）翼状骨形状的解剖学差异，并与短头型和中头型犬的正常形态相比，确定其在 FB 中的流行程度及其对气道横截面积的影响。
对接受头部检查的 FB 和可卡犬（CS）的 CT 研究进行了回顾。记录翼状骨的形状和横截面积，并在组间进行比较。
共纳入 36 只 CS 和 34 只 FB。与所有 36 只 CS 相比，34 只 FB 中有 79.41%（27/34）存在翼状骨异常形状，而所有 36 只 CS 均具有正常的翼状骨形状。仅 20.58%（7/24）的 FB 具有正常形状。FB 翼状骨水平的气道横截面积为 88.78mm。具有正常形状的 FB（平均值：95.70mm，SD ± 15.98）的气道面积大于具有异常形状的 FB（平均值：86.98mm，SD ± 20.32），但差异无统计学意义（>0.05）。可卡犬的气道横截面积大于 FB 两组的犬，平均值分别为 142.28mm（±24.87），差异有统计学意义（<0.05）。
法国斗牛犬翼状骨常呈异常形态。本研究确定了可能导致短头型犬上呼吸道阻塞的其他解剖学因素。
