What is a conductive deafness?
conductive deafness is the loss of hearing caused by a certain defect in the ability of the ear to perform sound waves. The sounds are muted or distorted due to a physical obstacle in an outer, middle or inner ear. In some cases, these obstacles pass naturally or can be removed by treatment, but some cases of conductive deafness are permanent. Sounds cause the ear drum to vibrate and these vibrations are transmitted in a number of bones called osicles to Cochle. The fluid inside the cochlea carries vibration and this movement is detected by small hair. The movement of these hair triggers signals into the brain and the signals are perceived as sound.
In the case of conductive deafness, the vibration string is interrupted somewhere along the road. Vibrations can be interrupted in any part of the ear, causing partial hearing loss or overall deafness. Any disruption along the nerve Pathway into the brain or in the brain's ability to translate an neural signal into a meaningful sound, is not classified as a conductive deafness, but instead it is called“Sensorineural deafness”. When the ear channel is blocked, the sounds reach the ear drum with less intensity, resulting in a muted sound. Foreign objects in the ear canal bring similar results. This is one of the easiest healing forms of conductive deafness.
perforation or rupture of the ear drum can also lead to a conductive deafness. Without a properly functioning ear drum, there is no mechanism that vibrates Osicles and transmit the sound to the cochle. Surgery is sometimes able to repair the damage to the ear drum, but in other cases the damage is permanent.
Obstruction in the middle ear often takes the form of fluid collection behind the ears, such as the medium of infection or otitis. The pressure in the middle ear prevents freely moves Osicles. If the pressure cannot be reduced by other means, such as the curing of antibiotics infection, stent may be required to drain fluid.
other conditionsThey can create solid obstacles in the middle ear. Otosclerosis causes mushroom bone tissue on the aspen, which hinders movement. The growth range determines the degree of hearing loss.
Incorrect pressure in Kochlea can also cause conductive deafness. Kochlea leaks during vibration transmission. Excess pressure, such as the pressure generated by inflammation of the inner ear, does not allow the liquid to move freely, which will again prevent vibration.
