Eardrum perforation

Ear bleeding often occurs when the eardrum is perforated or the skull base is fractured. The tympanic membrane is a thin film with certain toughness, which is located in the deep part of the external auditory meatus. The tympanic membrane is susceptible to rupture due to direct injury or indirect impact. Direct damage is more common when you pull out your ears or take a foreign object, and forceps, hairpins, or matchsticks into the external ear canal too deeply, which punctures the eardrum. Indirect impacts are more often caused by sound waves breaking the tympanic membrane during blasting; it can also be caused by diving, boxing ears or sudden falls during skating. When a head injury causes a skull base fracture, the tympanic membrane can also be injured and ruptured. Once the tympanic membrane ruptures, the ear suddenly feels severe pain, followed by tinnitus and deafness, and a small amount of blood flows out of the external ear canal, accompanied by dizziness, nausea and vomiting in severe cases. During otoscopy, blood can be seen in the external ear canal and irregular perforations of the eardrum. Patients with suspected tympanic membrane rupture should be sent to the hospital for examination and treatment as soon as possible.
