Use of cattles with cervical tumors as an experimental model of oropharyngeal neuropathies in equines

Abstract

In order to better understand the pathophysiology of diseases of the oropharynx in horses, endoscopy was performed in the oropharyngeal region of dairy and meat producing cattle, with the presence of tumors in the eyes, infra-auricular region or both regions (experimental model), analyzing what these tumors could cause in the innervation of their oropharynx and problems were observed in cattle very similar to those found in equine athletes such as epiglottic entrapment, collapse of the palatine arch, chondritis of the cuneiform recess, loss of palatal tone, but without respiratory symptoms, which we conclude that this model deserves more attention and can help us understand the nervous segments involved as well as the anatomical structures affected.
