Understanding pinna diseases is essential for veterinarians, pet owners, and anyone caring for dogs. The pinna, or external ear, plays a vital role in a dog's health and well-being, serving as a protective barrier for the sensitive inner ear, aiding in sound localization, and enhancing auditory perception. However, its anatomical features make it susceptible to various diseases, including infections, parasites, allergic reactions, traumatic injuries, and neoplastic conditions. Bacterial and fungal infections can cause inflammation, pain, and discharge in the pinna, necessitating proper diagnosis and treatment with antibiotics or antifungal medications. Parasitic infestations, such as ear mites and ticks, also target the pinna and require specific antiparasitic treatment. Allergic and immunologic disorders manifest as redness, swelling, and itching on the pinna, demanding accurate diagnosis and management strategies such as allergen avoidance, medications, or immunotherapy. Traumatic injuries, like hematomas, lacerations, and avulsion injuries, may affect the pinna, necessitating immediate attention to prevent infections and promote healing. Neoplastic diseases, both benign and malignant, require precise diagnosis and treatment planning. Understanding congenital and developmental disorders of the pinna is vital, as certain breeds may be predisposed to specific malformations leading to chronic ear problems. Genetic disorders affecting the pinna can contribute to hearing impairment or structural abnormalities, emphasizing the need for thorough assessment and management strategies. Recognizing the significance of pinna diseases enables early detection, intervention, and prevention strategies, emphasizing the importance of regular ear care and veterinary attention. By comprehending the anatomy and function of the pinna in dogs, optimal ear health and overall well-being for canine companions can be ensured.
