The tympanic membrane is a tough membrane located deep in the external ear canal and is an important part of the body’s sound conduction system and the first line of defense for the middle ear. It is often ruptured by palm strikes or explosive air wave impact, ear digging, forceful nose blowing, violent pharyngeal tube blowing, and temporal bone rock fracture. Don’t be nervous about a ruptured eardrum, first go to the hospital and check the size of the eardrum perforation and hearing loss to see if there is any hearing loss. A ruptured tympanic membrane may be accompanied by sudden and severe pain in the ear, followed by tinnitus, mild vertigo, nausea, vomiting, and bleeding in the external ear canal. Once the tympanic membrane is clearly broken, the following measures should be taken to avoid aggravation of the condition: 1. It is strictly forbidden to put medication into the ear or flush the external ear canal or blow powdered medication into the ear canal without the doctor’s consent to cover up the tympanic membrane perforation and to avoid causing middle ear infection. 2. If there are foreign bodies or mud in the ear, gently wipe the outer ear canal opening with a cotton swab dipped in 75% alcohol or 60 degree white wine, and then plug the outer ear canal opening with a sterilized cotton ball. 3. Be careful not to let water enter the ear when washing the face or bathing. 4. Do not block the external ear canal if the tympanic membrane is ruptured due to temporal bone fracture, and go to the hospital for timely treatment.
