In this first of a two-part series on demodectic otitis, Sue Paterson introduces the foundational concepts behind Otitis externa using the PPS system: Primary Causes, Predisposing Factors, Secondary Causes, and Perpetuating Factors. She focuses on demodectic otitis as a primary cause, explaining how certain breeds are predisposed and the distinction between localised and generalised demodicosis, with the latter often involving the ears. The video includes diagnostic tips, emphasising the importance of using lower magnification on cytology to avoid missing mites. Key takeaways highlight performing cytology in cases of generalised demodicosis—both unstained to detect mites and stained to identify secondary microbial infections.
