Tinnitus is the annoying sensation of phantom sounds in one or both ears. It is characterized by hearing a buzzing, clicking, ringing, swishing, roaring, hissing or whistling in one or both ears and the sound can vary in pitch from a high squeal to a low roar. At times the sounds are so loud that they interfere with being able to hear real sounds as well as your ability to concentrate; it can also come and go or it can be present all the time. There are two types of tinnitus, Subjective, which is tinnitus that only you can hear and is the most common and Objective, which your doctor can hear when doing an examination.
Subjective tinnitus is caused by problems of the middle, outer or inner ear or it can involve the auditory nerves, which is the part of the brain that interprets sounds. Objective tinnitus is rare and be caused by the blood vessels of the inner ear, muscle contractions or a bone condition of the inner ear. Tinnitus seems to originate in the ear or head and is usually not a serious problem but only a nuisance that in some cases resolves itself but in rare cases, tinnitus can be a symptom of serious underlying health condition.
What causes tinnitus?
The causes are many and vary from person to person. Nearly all people have normal body sounds that can be heard but we never pay any attention to these noises due to outside noise that mask them. Things like foreign objects in the ear, blockages by ear wax, infection, fluid or diseases of the tympanic membrane and middle ear bones are some causes of tinnitus. Other causes of tinnitus involve the microscopic endings of the nerves in the inner ear, advanced age, ear cell damage that causes a release of electrical signals that your brain interprets as sound, if the hairs in your inner ear or broken or bent, this can cause a “leak” of random electrical impulses to your brain.
More common causes of tinnitus are loud noises of any kind, stress or depression, TMJ, head or neck injuries, atherosclerosis, high blood pressure, and certain medications like antibiotics, cancer medications, diuretics, malaria medication, quinine, and aspirin taken in high doses. Everyone is at risk of getting tinnitus but some more than others including those with PTSD, and those who are subjected to daily loud noises. Tinnitus affects different people differently but some of the side effects include, fatigue, stress, problems concentrating, problems sleeping, depression, memory problems, anxiety and irritability.
Some treatments and relief remedies for tinnitus that your doctor may prescribe include a hearing aid, wearable sound generators, tabletop sound generators, acoustic neural stimulation, and or cochlear implants. To determine which treatment is best for you, your doctor will do an examination with a series of test that will tell the doctor if the tinnitus represents an underlying health concern. The most common test is an audiogram, other test include an auditory brainstem response (ABR), computer tomography scan (CT scan) or magnetic resonance imaging (MRI scan). It is time to see your doctor if tinnitus comes on suddenly and unexplained and accompanied by hearing loss or dizziness.
