What is an ear drum?
The ear drum is a part of the ear anatomy, which is designed to separate the outer parts of the ear from the middle ear. It protects medium air from damage and also serves other function and performs sound in the middle ear to allow hearing. Ear drums begin to appear very soon in the development of the fetus and errors during development can lead to hearing loss.
This structure is also known as the tympanic membrane. It consists of a very thin layer of skin that stretches through the ear canal. Roughly oval in the shape, the ear drum is slightly concave from the outside. The tissue is stretched on the bone rings that keeps it tense. The narrow opening in a circle near the upper part of the ear drum allows part of the tissue to be less tight and create a small area known as the pars flaccida.
When the sound is present in the environment, it creates vibrations in the ear. These vibrations cause that the tightly stretched skin to the ear vibrates and transmits movement on the small bones inside the ear known as the auditory osicles. This allows the brain to interact with sound waves andinterpret them as sounds. The auditory processing is very fast and provides immediate feedback when people interact with things in their environment that produce sounds.
Sometimes perforation may occur in the eardrum. This can be a congenital nature or caused by an infection that eats into the tissue. It is also possible for traumas such as head injuries to result in ear drum perforation. This causes a condition known as conductive hearing loss, where people cannot hear clearly because their ears are no longer able to vibrate sound waves.
perforations in some cases can naturally recover. Like other tissues in the body, the ear drum is designed to regenerate. During the therapeutic phases, it is very important to maintain the dry ear channel to prevent the middle ušaries and the patient may need to take drugs to treat infections. If perforation does not heal or deteriorate, P can be pRO treatment consider options such as surgery so that the patient can hear again.
symptoms of perforation may include ear pain, thick discharges, tinnitus and hearing problems. People who notice problems with the decent of experiencing trauma on their heads should consult a doctor to treat.
