Hint: A rupture eardrum, like a clap of thunder, can happen suddenly. You may feel a sharp pain in your ear, or an earache that you have had for a while suddenly goes away.it may also appear to have no sign of ear damage at all. The tympanic membrane perforation can lead to complications such as middle ear infections and hearing loss.
Complete answer: First we will understand what an eardrum is. Our eardrum is a really important part of the ear. Sound waves, which are collected by pinna from outside, travel through the ear canal to reach a structure called an eardrum or tympanic membrane. It is a thin flap of skin that is stretching tight like a drum and vibrates when sound hits it. These vibrations move the tiny bones of the idle ear, which send vibration to the inner ear. From the inner ear the message is sent to the brain.
The reason for this rupturing eardrum could be; having an ear infection. When the middle ear is infected, pressure builds up and pushes s against the eardrum. When the pressure gets too great, it can cause the eardrum to perforate.it can be noticed that the pain and pressure which existed because of infection, is not felt anymore and suddenly pus drains from the ear. Another common cause is poking the eardrum with foreign objects, like cotton buds, a bobby pin, or any other stuff which is used to swap the wax out.
Note: Otoscope is an instrument with a light used by doctors to look inside the ear. In most cases, there is a hole or tear in the eardrum, which could be seen using this device. Sometimes there may be too much wax or drainage for the doctors to clearly see the eardrum.
