What Are The Causes Of A Ruptured Ear Drum?
Many people have suffered a ruptured ear drum at some time in their lives; if you haven’t you may we know someone who has. This leads us on to the question; what causes a ruptured ear drum? There are many causes, here are a few of the more common ones. Infection. A middle ear infection can lead to a ruptured eardrum because the air space of the middle ear becomes full of pus which expands in volume, stretching and eventually perforating the eardrum in some cases. The stretching is painful; the main cause of the gradually increasing pain associated with otitis media. The pain is eventually relieved when the eardrum bursts. The tiny hole which forms allows air to enter the middle ear space, ventilating it and preventing fluid from reaccumulating. It also kills most of the germs that will cause the infection. Barotrauma. This means trauma to the drum from outside pressure. This can occur during scuba-diving, in an aeroplane or if the ear is exposed to a blast wave such as that which occurs during an explosion or when a huge lorry tire bursts near the ear. Ascending or descending in an aeroplane can cause the eardrum to burst if the individual suffers Eustachian tube dysfunction. Having this disorder means that the tube does not equalise the pressure outside with that of the middle ear due to blockage. Scuba-diving can cause rupture in the same way. Normally a diver will equalise the pressure on ascent by allowing it to travel through the Eustachian tube, again if this blocked then rupture is far more likely.
