The results of the examination of the eardrum can cause deafness?

The ear is a very important part of our body. If we can’t hear the sound in our ears, then we will lose a lot of fun in life and our life will become difficult. We will not hear every little spring and summer. The sound of the birds, we walked to the sea to hear the sound of the sea, and our communication with others became very troublesome. Then what would we cause deafness besides the natural deafness? Does the perforation of the eardrum cause the perforation of the eardrum?


Tympanic membrane perforation is a kind of middle ear trauma caused by violence, traffic accidents, or changes in air pressure. The motherland medicine belongs to the category of “ear leaking tube”. Tympanic membrane perforation is often encountered in forensic clinical identification, and there are many reasons for the perforation of the tympanic membrane. It is mainly divided into traumatic(Direct or indirect external force)Tympanic membrane perforation and inflammatory tympanic membrane perforation, the former such as blunt tools(Including palm, boxing, etc.)Strike, skull base fracture, explosion, ear accident, acupuncture, burns and even insects can be caused. The traumatic tympanic membrane perforation discussed here mainly refers to traumatic tympanic membrane perforation caused by indirect external force. Inflammatory tympanic membrane perforation is mainly Found in acute otitis media and chronic otitis media.

The eardrum, also known as the tympanic membrane, is deep in the external auditory canal, only0.1mmThick, like a layer of “window paper”, is very susceptible to direct or indirect external force and rupture, more common in the external auditory canal excavation, not standardizing the ear, flushing excessive force or bursting, diving and other sudden vibrations.

Although the eardrum is small, it can drive the vibration of the small bone in the middle ear, and plays an important role in the auditory conduction function. It can also separate the outer ear from the inner ear to protect the middle ear cavity. For this reason, once the eardrum is perforated, there are two disadvantages: the protection of the middle ear is impaired. The eardrum is the side portal of the middle ear, which separates the outer ear from the middle ear to protect the middle ear cavity. After perforation, external bacteria, sewage, and foreign matter can be perforated into the middle ear, which induces infection and pus in otitis media, and the risk of forming cholesteatoma. The second is perforation, which reduces hearing. When the sound is transmitted to the ear, the eardrum is first vibrated and then transmitted to the cochlea through the middle ear ossicular chain, which causes the nerve to form a hearing. After perforation of the eardrum, the effective vibration area of ​​the eardrum is reduced, and the external sound wave energy is transmitted to the inner ear, which will directly lead to hearing loss.

Trauma caused by trauma to the eardrum, if there is no infection, can be2~3Weekly self-healing, but if accompanied by suppurative otitis media or ear infections, you should choose surgery under the microscope as soon as possible, both to remove the lesions, but also to repair the perforation, and restore hearing in time, which is what we usually call tympanic molding Surgery not only eliminates inflammation of the middle ear, but also repairs the damaged eardrum, ossicular chain and other sound transmission systems to improve and restore hearing.

Deafness is a thing that we can’t even think about for normal people. So we are more afraid of deafness. When there is something wrong with our ears, we always worry about whether we will cause our ears to lick, eardrum. Perforation is a great deal of damage to our ears but it does not cause complete deafness.
