TLDR The document concludes that accurate diagnosis is crucial for effectively treating various ear diseases in dogs and cats.
The document reviewed diseases affecting the pinna in dogs and cats, highlighting aural hematomas, eosinophilic pinnal folliculitis, ear margin seborrhea, fly strike, periodic alopecia, pinnal alopecia, and proliferative thrombovascular necrosis. Aural hematomas were noted as common in dogs with pendulous ears, with treatment options ranging from surgery to less invasive methods. Allergic diseases like atopy and food allergies were mentioned as causes of pinnal erythema, diagnosed through skin testing or diet trials. Other conditions such as dermatophytosis, actinic dermatitis, lichenoid dermatoses, granulomatous nodules, and immune-mediated vasculitides were discussed, each with specific diagnostic and treatment approaches. The document stressed the importance of accurate diagnosis, including the use of fungal cultures, allergy tests, and biopsies, to effectively treat pinnal diseases.
