The purpose of this study was to evaluate the prevalence of intranasal mucosal contact points in brachycephalic and normocephalic dogs. In total, 82 brachycephalic dogs (42 pugs and 40 French bulldogs) were evaluated by rhinoscopy for their intranasal mucosal contact and 25 normocephalic dogs were evaluated as a control group. Of those, 162 brachycephalic nasal cavities were evaluable and 140 had contact between intranasal structures (87%). Intraconchal and septoconchal mucosal contact points were the most commonly detected sites of contact. French bulldogs had a significantly higher prevalence of mucosal contact and had 3 mean contact points compared with 1.7 mean contact points per nasal cavity in pugs. Septal deviations were present in 62% of brachycephalic dogs. In the control group, mucosal contact points were present in only 7 of 50 nasal cavities (14%), and septal deviations occurred in 16% of those cases. Contact point average was 0.1 in large and 0.3 in small normocephalic dogs. Intranasal mucosal contact was identified as a common and previously unreported problem in brachycephalic dogs. Numerous contact points reduce the lumen of the intranasal passageways and indicate potential intranasal obstruction. Affected dogs might benefit from removal of obstructing conchae, potentially using laser-assisted turbinectomy.
本研究的目的是评估短头犬和标准头型犬鼻内粘膜接触点的患病率。总共对82只短头犬（42只哈巴狗和40只法国斗牛犬）进行了鼻镜检查，以评估其鼻内粘膜接触情况，并将25只标准头型犬作为对照组进行评估。其中，162个短头犬鼻腔可进行评估，140个鼻腔存在鼻内结构间的接触（87%）。鼻甲内和鼻中隔与鼻甲间的粘膜接触点是最常检测到的接触部位。法国斗牛犬的粘膜接触患病率显著更高，平均每个鼻腔有3个接触点，而哈巴狗每个鼻腔平均有1.7个接触点。62%的短头犬存在鼻中隔偏曲。在对照组中，50个鼻腔中只有7个（14%）存在粘膜接触点，其中16%的病例出现鼻中隔偏曲。标准头型大型犬的接触点平均为0.1，小型犬为0.3。鼻内粘膜接触被确定为短头犬中一个常见且此前未报道的问题。大量的接触点会减小鼻内通道的管腔，并提示可能存在鼻内阻塞。受影响的犬只可能受益于切除阻塞性鼻甲，可能采用激光辅助鼻甲切除术。
