Bleeding from a perforated eardrum for 2 days is usually caused by traumatic perforation of the eardrum. If the bleeding is small, it can usually be stopped on its own, but if the bleeding is large, it needs to be treated promptly, and if necessary, surgery should be performed to stop the bleeding. Traumatic tympanic membrane perforation is usually caused by indirect external forces (such as diving, airplane landing and takeoff, explosion, etc.) and direct external forces (such as cotton swabs, ear spoons, etc. directly pierced), when the tympanic membrane cracks or perforation, it can lead to bleeding, and may be accompanied by ear pain, hearing loss, tinnitus and other symptoms. The amount of bleeding is usually small and can stop on its own. During a traumatic tympanic membrane perforation, it is important to avoid water in the ear canal, keep the ear canal dry and clean, avoid blowing the nose too hard, and avoid infections. Medical attention is recommended to remove foreign bodies and blood clots from the ear, as well as to disinfect the ear canal with a 75% ethanol swab. Prohibit rinsing of the ear canal or dropping of medication, and the mouth of the external ear canal can be blocked with a sterilized cotton ball to reduce the chances of infection. If the bleeding cannot be stopped on its own, after first ruling out bleeding caused by skull base fracture, surgical treatments such as tympanic membrane patch and tympanoplasty can help the tympanic membrane heal or repair the tympanic membrane so as to stop bleeding. If there is a combination of infection, anti-infection treatment is needed. Patients with perforated tympanic membrane bleeding for 2 days are recommended to seek timely hospital consultation and standardized treatment.
