Loss of hearing ability or deafness can occur genetically (congenital), due to accidents, or due to the aging process which reduces all the ability of the senses, including the ear. However, not only that, deafness can arise due to certain diseases. Do you know what diseases cause deafness? Check it out below.
1. Otosclerosis
Otosclerosis is a condition of abnormal ear bone growth. Otosclerosis is the most common cause of deafness.
This abnormal growth of the inner ear bone will interfere with the sound capture process so that sound waves cannot be picked up properly by the ear.
One of the symptoms in otosclerosis is that the head feels dizzy, the ear feels ringing in one ear or both, and the hearing gradually diminishes until it completely disappears.
2. Meniere's disease
Meniere's is an ear disease that interferes with the flow of inner ear fluid. This inner ear is the part that functions to regulate hearing and balance.
Meniere's condition will cause vertigo and a sensation of kliyengan. This disease can also lead to loss of hearing ability.
This loss of hearing ability is due to the buildup of excess fluid in the ear in the labyrinth. As a result, there is a balance disturbance in it and sound waves cannot be picked up. Reported on the Healthline page, this disease often disturbs one side of the ear.
The cause of this disease is still unknown. However, scientists believe that this is due to changes in fluid in the inner ear tube. In addition, it is also thought to be due to autoimmune diseases.
3. Acoustic neuroma
Acoustic neuroma is a benign tumor that affects the nerves that connect the ear to the brain. This disease is a rare condition. The growth of these tumors will occur at a very slow pace for years which is often not realized.
The larger the tumor, the more problems it will cause, one of which grows pinching the cranial nerves associated with the auditory nerve. Therefore, this disease can be a cause of deafness or hearing loss.
Symptoms of this condition are usually hearing loss, a feeling of fullness in one ear, loss of balance, headaches, and facial numbness or tingling.
4. German measles
German measles is caused by the rubella virus which can interfere with fetal growth. This virus attacks the developing fetus. There are various disorders that can arise due to the rubella virus attack, one of which is attacking the hearing nerve. That way, babies can be born deaf.
Symptoms of the occurrence of German measles are not really that obvious. However, there are some symptoms that you need to pay attention to such as the appearance of a pink rash, fever, painful joints, swollen glands during pregnancy. Therefore, pregnant women should be very careful with this condition.
5. Presbycusis
Presbycusis is an ear disorder that affects the inner as well as the middle ear. Presbycusis is caused by a change in the blood supply to the ear, thus causing sensorineural hearing loss.
Sensorineural disorders occur as a result of damage to the hearing organs or hearing nerves. Hearing loss that occurs is often associated with age. About 30-35 percent of hearing loss occurs in people aged 65 years and over, while 40-45 percent occurs in seniors over 75 years.
6. Mumps
Mumps is a viral infection that occurs mainly in children. This disease causes the salivary glands to become inflamed, resulting in swollen cheeks or jaw. In addition to swollen cheeks, usually accompanied by fever, headache.
The mumps virus if not handled properly can also be dangerous. The mumps virus can damage the cochlea (cochlea) or the cochlear part of the inner ear. This part of the ear contains hair cells that convert sound vibrations into nerve impulses that the brain reads as sound. Although mumps can cause deafness, it is not the most common case.
