Abstract:Dog ear itch acariasis is a skin parasitic disease caused by dog ear itch mites (Otodeces cymotis) parasitizing in the ear canal. Dog ear hematoma is a swelling formed between ear cartilage and the inner skin of auricle due to the external force that causes the blood vessels of dog ears to rupture and bleed. Ear itch acariasis is an important cause of ear hematoma. Once it occurs, it needs to be treated in time, and surgery is used in severe cases. A case of ear hematoma caused by ear itch acariasis was diagnosed and treated. The diagnosis and treatment process and related analysis were specifically introduced for clinical reference.
