Causes of Deafness:
The Deafness can be genetic or acquired. There are numerous causes that can impair hearing. Some are transient and easy to resolve, such as ear canal wax accumulation with the feeling of ear plugging and malaise that is among the main causes of the transient condition.
Another cause of this condition is otitis, which in most cases can be treated with antibiotics, and resolution is total.
In some situations, otitis can cause permanent structural changes (destruction of the eardrum) where treatment already involves surgery and the prospect of rehabilitation of hearing capacity is lower.
The symptoms are quite variable. Some patients with sudden deafness reported hearing an explosive sound in the affected ear when the injury first occurred. In these cases the sudden condition was accompanied by persistent tinnitus and vertigo that usually subsides within a few days.
But in general, the sudden condition is a clear perception of decreased hearing, ringing and dizziness , and a feeling of pressure in the ears , as if the ear is clogged or plugged.
Treatment for deafness depends on its cause, such as cleaning or draining the ear when there is accumulation of wax or discharge, or performing surgery in cases of perforated eardrum or to correct any deformity, for example.
However, hearing recovery may require the use of hearing aids or electronic device implants. Learn more when hearing aid is required and major types. After indicating the hearing aid, the audiologist will be the professional responsible for guiding the use, the type of hearing aid, and adapting and monitoring the hearing aid for the user.
