Common causes of bleeding from the ear can be injury to the external auditory canal, acute inflammation of the external auditory canal, injury to the eardrum, inflammation of the middle ear, and benign or malignant tumors of the inner and middle ear, and other related conditions. The most common cause of ear canal bleeding due to injury to the external auditory canal is a break in the skin of the ear canal caused by pulling out the ear with a hard object. If the damage is not very serious, generally keep the ear canal clean and dry, most of them can heal by themselves; if the damage to the ear canal is more serious, there is inflammation of the external auditory canal, we need to use medication to treat it, the ear canal can be used locally to soak with ofloxacin ear drops, and at the same time, we also need to take antibiotics orally to prevent infections, commonly used antibiotics are amoxicillin clavulanate potassium, cefuroxime, and so on. Bleeding from the ear canal caused by tympanic membrane injury is usually less bleeding, and most of it is due to perforation of the tympanic membrane caused by trauma. For the treatment of this condition, first of all, we should keep the outer ear canal to avoid water pollution, and secondly, we should try to avoid cold and flu, you can take some oral antibiotics to prevent infection, and if there are symptoms of tinnitus, you can take methylcobalamin and ginkgo biloba orally. Generally, small tympanic membrane perforations can heal on their own within three months, but if they don’t heal in more than three months, surgery is needed. The vast majority of ear bleeds caused by inflammation of the middle ear or benign or malignant tumors in the inner ear require surgical treatment in order to recover. Therefore, if the ear bleeds only a small amount, there is usually no need to be overly nervous. If the ear canal bleeds frequently, repeatedly and in large quantities, it is best to go to the hospital for an endoscopic examination of the ear canal and a high-resolution CT examination of the temporal bone to identify the specific cause of the bleeding and then target treatment.
