This study, which involved 868 patients, focused on size-dependent features (body size, pinna formation, brachycephaly, overweight) and their associations with the occurrence of canine Otitis externa. Breed, sex, and neuter status were also included. Canine patients diagnosed with Otitis externa presented between 1 January 2019 and 31 July 2022 in a referral small animal hospital were included, while dogs with matching categories presented at the Unit for Reproductive Medicine in the same time period functioned as a randomized control group. Statistical analyses included Pearson-Chi test, Fisher's exact test, and Bonferroni correction. -values of <0.05 were considered statistically significant. Rhodesian Ridgebacks, non-brachycephalic breeds, intact female dogs, dogs with semi-erect ears, and large-sized breeds had a significantly reduced risk of developing Otitis externa. Conversely, Pugs, French Bulldogs, Cocker Spaniels, medium-sized breeds, dogs with erect ears, brachycephalic breeds, neutered female, and neutered male patients were more frequently diagnosed with Otitis externa. The study concluded that large breed dogs showed a reduced risk of developing Otitis externa in our data set as well as meso- and doliocephalic breeds and dogs with semi-erect pinna formation. Particularly, the Rhodesian Ridgeback and intact female dogs showed a significantly low risk of suffering from Otitis in the current study.
这项研究涉及868只犬类患者，重点关注体型相关特征（体型大小、耳廓形态、短头畸形、超重）及其与犬外耳炎发生的关联。研究还纳入了品种、性别和绝育状态等因素。纳入了2019年1月1日至2022年7月31日期间在一家转诊小型动物医院被诊断为外耳炎的犬类患者，而同期在生殖医学科就诊的具有匹配分类的犬类作为随机对照组。统计分析包括Pearson卡方检验、Fisher精确检验和Bonferroni校正。P值<0.05被认为具有统计学意义。罗得西亚脊背犬、非短头品种、未绝育雌性犬、耳朵半直立的犬以及大型品种患外耳炎的风险显著降低。相反，哈巴狗、法国斗牛犬、可卡犬、中型品种、耳朵直立的犬、短头品种、绝育雌性犬和绝育雄性患者更常被诊断为外耳炎。研究得出结论，在我们的数据集中，大型犬以及中头型和长头型品种以及耳廓半直立的犬患外耳炎的风险降低。特别是，罗得西亚脊背犬和未绝育雌性犬在本研究中患外耳炎的风险显著较低。
