leading deafness is hearing loss caused by a bug in the ear’s ability to perform sound waves. sounds are attenuated or distorted due to a physical obstruction in the outer, middle or inner ear. in some cases, this obstacle naturally or can be removed by processing, but some cases of conductive deafness is permanent.
perforation or rupture of the eardrum may also result in leading deafness. without a functioning eardrum, there is no mechanism to vibrate the ossicles and get the sound to the cochlea. Surgery is sometimes able to repair damage to the eardrum, but in other cases the damage is permanent.
obstruction of the middle ear often takes the form of fluid accumulation behind the eardrum, such as an infection or otitis media. pressure in the middle ear prevents the ossicles move freely. when the pressure can not be reduced by other means, such as curing an infection with antibiotic, a stent may be necessary to drain the fluid.
other conditions can create solid objects in the middle ear. otosclerosis causes spongy bone tissue to form on the ossicles, preventing movement. scope of growth determines the degree of hearing loss.
incorrect pressure in the cochlea can cause conductive deafness as well, a leak in the cochlea will drain away the liquid important in the transmission of vibrations overpressure, such as created by the inflammation of the inner ear, not allowing fluid to move freely again prevent vibration.
