Plain-English summary
In this study, four horses with ear infections (otitis media/interna) were examined using a procedure called endoscopy, which lets vets look inside the ear without needing to do surgery. One horse was having trouble with persistent head shaking, while the other three showed sudden problems with their face and balance. During the examination, all four horses had abnormal growths found in the bones near their ears. This endoscopic method is safer than traditional imaging techniques and avoids the risks that come with putting the horses under general anesthesia. Overall, the endoscopy helped in diagnosing the ear infections effectively.
Abstract
Endoscopic examination of the auditory tube diverticula was a diagnostic aid in the evaluation of 4 horses with otitis media/interna and associated osseous changes of the stylohyoid and petrous temporal. One of the horses was examined because of persistent head shaking; the other 3 were examined because of an acute onset of facial and vestibulocochlear nerve dysfunction. Proliferative lesions involving the petrous temporal bone and proximal portion of the stylohyoid bone were identified endoscopically in all 4 horses. Endoscopy is a noninvasive procedure that provides an alternative to skull radiography and tympanocentesis in the diagnosis of otitis media/interna in horses. In addition, risks associated with general anesthesia are avoided.
