| 中文描述 | 環狀軟骨紊亂由於持續的嚥下困難在年輕狗是罕見的，有直到斷奶經常未被注意的徵兆。可能起因於咽部收縮肌跟在食道上面的括約肌不協調所致，或者在吞嚥期間由於環狀軟骨不能鬆弛造成弛緩不能。 可能有次發性咽頭炎，扁桃腺炎，鼻涕排出或者吸入型肺炎。 |
| 英文描述 | Cricopharyngeal disorders are rare causes of persistent dysphagia in young dogs, with signs often unnoticed until weaning. Can be caused by incoordination between the pharyngeal contractor muscles and relaxation of the upper esophageal sphincter, or be due to achalasia, which is the lack of relaxation of the cricopharyngeal muscles during swallowing. There can be secondary pharyngitis, tonsillitis, nasal discharge, or aspiration pneumonia. |
