There are two aspects to treatment, dealing with the haematoma itself and dealing with the underlying cause of the ear irritation. Firstly, surgery will be performed to remove the blood clot and the space left between the skin and cartilage using special sutures. This will prevent another haematoma forming. Secondly the cause of the ear irritation must be diagnosed and treated otherwise the problem may reoccur. The most common cause of ear irritation is an ear mite infestation. Other causes include:- ectoparasites, allergic diseases, masses, polyps or foreign bodies in the ear canal.
