This report outlines two cases of ptyalism that were not associated with oral conditions or primary dysphagia. The first, a 9‐year‐old Thoroughbred gelding, was associated with left‐sided peripheral vestibular disease and bone modelling around the left tympanic bulla. The second, a 7‐year‐old Dutch Warmblood mare, was associated with progressive bilateral laryngeal paralysis and a mediastinal T‐cell lymphoma. In Case 1, a neurological pathophysiology was proposed involving altered autonomic innervation of the salivary glands; whilst in Case 2, the mechanism remains unclear but may have involved mechanical compression of the intrathoracic oesophagus or stimulation of afferents within the vagus nerve. This case series highlights rare causes of ptyalism that have not been previously reported in the literature.

两匹马中的人格主义的异常病理生理机制

该报告概述了两例与口腔疾病或原发性吞咽困难无关的精神分裂症病例。第一次是9岁的纯血胶，与左侧外周前庭疾病和左侧鼓膜周围的骨骼建模有关。第二例是7岁的荷兰Warmblood母马，与进行性双侧喉瘫痪和纵隔T细胞淋巴瘤有关。在案例1中，提出了神经病理生理学，涉及唾液腺自主神经的改变。在案例2中，机制尚不清楚，但可能涉及对胸腔内食管的机械压迫或对迷走神经内传入神经的刺激。该案例系列突出了以前没有文献报道过的导致ptyalism的罕见原因。
