2017 ACVIM Forum Research Abstract Program

The results revealed moderate hyperplasia equally developed throughout the epithelial layer surrounding the ME and neutrophil-rich mild inflammatory cell infiltration; more pronounced at one week obstruction compared to 2 days. Moreover, the majority of the ME cleft was filled with serous effusion. At 2weeks post-obstruction, hyperplasia, edema and hyper vascularization of the ME epithelial layer were severe and there was an increased number of inflammatory cells within the serous effusion. After 4 weeks, there was a transition of ME effusion from serous to mucoid with an increased infiltration of plasma and other mononuclear cells, as well as very severe epithelial hyperplasia. In addition, granulation tissue appeared to originate from the extracellular matrix in the ME cavity and round window niche. ME epithelial hyperplasia and characteristics of ME effusion were directly proportional to the duration of ETO. Therefore, patients presented with long-lasting complaints of ocular and nasal discharge, epistaxis, sneezing, otorrhea, ear itching, head tilt, facial nerve paralysis, and noisy and difficult breathing should be examined for dysfunction or blockage of the Eustachian tube by diagnostic techniques such as tympanometry. The purpose of this study was to assess the effects of age, body condition score (BCS) and muscle condition score (MCS) on indirect radial and coccygeal Doppler systolic arterial blood pressure (SAP) measurements in dogs.
