Abstract

Objective: 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.

Animals and procedure: 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.

Results: 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 mm². The area was larger in FB with normal shape (average: 95.70 mm², SD ± 15.98) than those with abnormal shape (average: 86.98 mm², SD ± 20.32), though this difference was not statistically significant (P > 0.05). Cocker spaniels had a larger airway cross-sectional area than dogs in both FB groups, with a mean of 142.28 mm² (± 24.87) and P < 0.05.

Conclusion and clinical relevance: 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.

法国斗牛犬翼状骨形状异常：发病率及其对横截面积的影响。

目的：对计算机断层扫描图像进行回顾性观察，以描述法国斗牛犬（FB）翼状骨形状的解剖差异，并确定其发生率及其对呼吸道横截面的影响：回顾性观察计算机断层扫描图像，描述法国斗牛犬（FB）翼状骨形状的解剖学差异，并确定其发生率及其对气道横截面积的影响，与正常畸形犬和中脑犬进行比较：对接受头部检查的 FB 和可卡猎犬（CS）进行计算机断层扫描研究。记录翼状骨的形状和横截面积，并进行组间比较：结果：共纳入 36 只 CS 和 34 只 FB。在 79.41%（27/34）的 FB 中，翼骨形状异常，而在所有 36 例 CS 中，翼骨形状正常。只有 20.58%（7/24）的 FB 形状正常。FB 翼骨水平的气道横截面积为 88.78 平方毫米。形状正常的 FB 的横截面积（平均：95.70 平方毫米，标准差 ± 15.98）大于形状异常的 FB 的横截面积（平均：86.98 平方毫米，标准差 ± 20.32），但差异无统计学意义（P > 0.05）。可卡猎犬的气道横截面积比两个 FB 组的犬都大，平均为 142.28 平方毫米（± 24.87），P < 0.05：法国斗牛犬的翼状骨经常会出现异常。本研究发现了可能导致肱骨发育不良犬上呼吸道阻塞的更多解剖因素。

期刊介绍： The Canadian Veterinary Journal (CVJ) provides a forum for the discussion of all matters relevant to the veterinary profession. The mission of the Journal is to educate by informing readers of progress in clinical veterinary medicine, clinical veterinary research, and related fields of endeavor. The key objective of The CVJ is to promote the art and science of veterinary medicine and the betterment of animal health. A report suggesting that animals have been unnecessarily subjected to adverse, stressful, or harsh conditions or treatments will not be processed for publication. Experimental studies using animals will only be considered for publication if the studies have been approved by an institutional animal care committee, or equivalent, and the guidelines of the Canadian Council on Animal Care, or equivalent, have been followed by the author(s).
