The aims of this study were to assess the impact of epidemiological variables, severity of presurgical respiratory signs, diagnostic findings from pharyngeal and laryngeal examination using a new grading scheme and CT scan images, on postsurgical outcome in dogs undergoing surgery for brachycephalic obstruction airway syndrome (BOAS).
An owner-based questionnaire was used to grade dogs based on their respiratory signs before surgery and at least six weeks after surgery. Epidemiological data and results from presurgical pharyngeal and laryngeal examination and CT scan findings for 75 dogs undergoing airway surgery were collected from the medical records.
70.7 per cent of dogs showed an improvement in respiratory signs following rhinoplasty and palatoplasty. This improvement was associated with the severity of inspiratory efforts and the Poncet score on presentation, but not with any other clinical sign or anatomical abnormality found during BOAS assessment, nor by the degree of craniofacial shortening as determined by CT-scan. Presurgical snoring was positively associated with the degree of narrowing of pharyngeal dimensions.
Dogs presenting with clinical signs of BOAS benefit from rhinoplasty and palatoplasty alone. The degree of narrowing of pharyngeal dimensions appears to be associated with severity of snoring while soft palate length alone was not.
本研究旨在评估流行病学变量、术前呼吸征象严重程度、使用新分级方案进行的咽和喉检查的诊断结果以及 CT 扫描图像对接受短头气道阻塞综合征（BOAS）手术的犬手术后结果的影响。
使用基于主人的问卷，根据犬术前和至少术后 6 周的呼吸征象对犬进行分级。从病历中收集了 75 只接受气道手术的犬的流行病学数据和术前咽喉检查结果以及 CT 扫描结果。
70.7%的犬在接受鼻整形术和腭成形术后呼吸征象得到改善。这种改善与吸气努力的严重程度和入院时的 Poncet 评分相关，但与 BOAS 评估期间发现的任何其他临床征象或解剖异常无关，也与 CT 扫描确定的颅面缩短程度无关。术前打鼾与咽径狭窄程度呈正相关。
患有 BOAS 临床症状的犬仅接受鼻整形术和腭成形术即可获益。咽径狭窄程度似乎与打鼾严重程度相关，而单纯软腭长度与之无关。
