The eardrum, also known as the tympanic membrane, is an elastic, grayish translucent membrane that separates the outer ear canal from the middle ear. It acts as a protective membrane for the ear, and the presence of outside viruses or bacteria means that a perforation has occurred. The onset of a perforated eardrum can result in some damage to the protective role of the middle ear, which is the gateway to the middle ear, separating the outer ear from the middle ear and protecting the middle tympanic membrane. Eardrum perforations are usually caused by violent cases, traffic accidents, or trauma to the middle ear caused by changes in air pressure, and are classified as “ear door leakage” in Chinese medicine. Eardrum perforation is often encountered in forensic clinical identification, and can be caused by many factors, mainly traumatic (direct or indirect external force) eardrum perforation and inflammatory eardrum perforation, the former such as blunt tool (including palm, fist, etc.) blow, skull base fracture, explosion, ear digging, needle prick, scalding and even insects into the ear can be caused, here we introduce traumatic eardrum perforation mainly refers to indirect The traumatic eardrum perforation we are going to introduce here mainly refers to the traumatic eardrum perforation caused by indirect external force, while the inflammatory eardrum perforation is mainly caused by acute otitis media and chronic otitis media. Eardrum perforation is very dangerous and patients should receive timely treatment as it is the key to protect their health. A perforated eardrum can not only infect adjacent organs and tissues, but also affect the patient’s hearing. This can cause even more damage and complications. Therefore, it is important to go to a regular hospital for treatment and examination after the eardrum is perforated, so as not to delay the best time for treatment and persecution of the patient’s health. The above is a brief introduction to perforated eardrums, which should not be ignored because of lack of understanding of the treatment of perforated eardrums.
