Permanent hearing loss does not occur suddenly in most cases, but rather the result of health accumulations, environmental or even genetic factors that gradually affect the ability of the ear to capture sounds or transfer them to the brain, and some of these reasons can be avoided or reduced their effects if they are identified early, while there are other reasons that lead to damage that cannot be treated and the result is a permanent loss of hearing, and we monitor them.
Continuous exposure to high noise
Listening to high -end sounds without protection that causes permanent damage to the micro -hair cells inside the inner ear, and these cells are not renewed in humans, which means that any damage that affects it always remains, and the use of ear headphones is loudly or working in places that contain continuous industrial noise such as factories and airports is one of the most reasons that lead to this type of damage.
Severe or chronic infection in the ear
Some types of infection, such as otitis, if not properly treated, may extend to the inner ear and affect the auditory nerves, and the repetition of infection or the presence of fluids behind the eardrum for long periods of time causes gradual harm in the auditory structure, especially in children who are exposed to these cases frequently without paying attention to their future danger.
Genetic and moral factors
Some people are born with hearing problems as a result of a defect in the genes or defects in the formation of the ear, and these problems may not appear at birth directly but rather develop with time, and the presence of a family history of hearing loss makes the possibility of infection higher, especially if they are associated with other genetic diseases that affect the nerves or bones inside the ear.
Take some medications with a toxic effect on the ear
There are drugs known for their negative effect on auditory nerves or inner ear, and are known as Ottoxian medications such as some types of antibiotics, urine drugs and cancer medications, and these medications may cause a gradual loss of hearing that cannot be retracted, so their use requires accurate supervision and periodic assessment of hearing throughout the treatment period.
Head or ear injuries
Strong strikes on the head or direct bumps to the ear can lead to torn eardrum, auditory nerve damage, or even shattering the fine bones inside the ear, and these injuries may lead to immediate or gradual loss of hearing, and often it is always if the injury is severe or not treated urgently.
Chronic diseases and their effect on hearing
Some chronic diseases such as diabetes and vascular diseases may indirectly affect hearing, as they lead to poor blood circulation that nourish the inner ear, which reduces its efficiency and increases the chances of damage to it, and that autoimmune diseases may cause infections inside the ear lead to permanent hearing loss if they are not diagnosed in time.
