Tympanic membrane perforation is a common pathology in otology and can be caused by trauma or by acute purulent otitis media or chronic purulent otitis media. The tympanic membrane is located in the inner wall of the external ear canal and is a thin membrane-like tissue that separates the external ear canal from the middle ear, preventing foreign objects such as bacteria and dirty water from entering the middle ear and causing purulent otitis media. Because of its thinness, the tympanic membrane is susceptible to various traumas that can lead to perforation of the tympanic membrane, while purulent inflammation of the middle ear can also cause perforation of the tympanic membrane. A perforated tympanic membrane can lead to varying degrees of hearing loss. If the tympanic membrane is perforated due to trauma, the perforation is small and there is no secondary bacterial infection, it will usually heal itself in 3-4 weeks. If the perforation is large and does not heal on its own in 3 months, it will require tympanoplasty treatment. In the case of acute suppurative otitis media, if the inflammation is completely controlled, the perforation is relatively small, and no more recurrent episodes occur, it will also slowly heal on its own. If chronic suppurative otitis media or acute suppurative otitis media recurs and the tympanic membrane perforation does not heal on its own, tympanoplasty, or tympanoplasty, depending on the tympanic membrane perforation, is the treatment of choice. After traumatic tympanic membrane perforation, water in the ear canal, any drops in the ear canal, nasal blowing and avoiding colds are prohibited. This is to avoid secondary bacterial infection of the middle ear and to promote self-healing of the perforated eardrum.
