A hole in the eardrum is caused by trauma, i.e. perforation of the tympanic membrane. If the tympanic membrane is perforated in a small way and is not infected, the perforation usually heals on its own and does not require special treatment; if the perforation is large or infected or does not heal for a long period of time, it can be repaired surgically in the hospital. The eardrum is the deepest membrane in the external auditory canal, and is an important structure for conducting sound, usually with a certain degree of elasticity and toughness. When the eardrum is subjected to external forces, it may become perforated. Smaller perforations can have no noticeable symptoms, while larger perforations can cause ear pain, tinnitus, and hearing loss. It is recommended that you seek medical attention when a perforated eardrum occurs. 1. Remove foreign bodies, blood clots and pus from the external auditory canal. 2. Avoid catching colds and do not blow your nose too hard to prevent infection from the nasopharynx. If there are no signs of infection, antibiotics are not necessary. 3. If there is no secondary infection, do not use rinsing or medication drops in the external auditory canal. Before the perforation heals, swimming or any water in the ear is prohibited. Most traumatic perforations heal spontaneously within 3-4 weeks. For larger perforations, the remnants of the tympanic membrane can be repositioned into the tympanic chamber under aseptic microscopic manipulation, and the surface of aseptic paper can be used to promote tympanic membrane healing. If the perforation does not heal, tympanic membrane repair can be performed on an elective basis. When the tympanic membrane perforation occurs because of trauma, you should go to the hospital in time, complete the relevant examination, to clarify the scope and extent of the damage, and follow the doctor’s instructions for standardized treatment.
