Tinnitus is the medical term for the perception of sound in one or both ears or in the head when no external sound is present. Although there have been tremendous advances through research, the exact physiological cause or causes of tinnitus are not known. Noise exposure – Exposure to loud noises can damage and even destroy hair cells, called cilia, in the inner ear.
Certain disorders, such as hypo- or hyperthyroidism, Meniere’s disease, Lyme disease, fibromyalgia, and thoracic outlet syndrome, can have tinnitus as a symptom. Ototoxicity – Some medications are ototoxic, that is, the medications are harmful or damaging to the ear. Although there presently is no cure, in some cases, tinnitus can be managed by treating the underlying cause or by altering reactions to it. The phrase “prevention is the best medicine” could have been coined specifically for tinnitus. When poor physical health is to blame for tinnitus, correct the underlying medical issue(s) are sometimes all it takes to get rid of the ringing in the ears. While it is not clear exactly why they work, certain antidepressant medications can correct or reduce tinnitus.
Benzodiazepines (most famously, Valium and Ativan) have been tried in tinnitus with mixed results. When tinnitus is a symptom on Meniere’s disease, surgical therapy might be able to correct the dizziness and ear fullness while at the same time eradicating tinnitus. While they have not yet been perfected, there are various types of electrical and mechanical devices that have been used to treat tinnitus. A tinnitus masking device is quite similar to a hearing aid in form but not necessarily in function. My foundation in faith and family has allowed me to face challenges and grow into an expert in hearing health care. If you feel that you would like to have your hearing tested, you can call us on 01494 733840 to make an appointment, with or without a medical referral. Before your appointment, if time allows, we will invite you to complete a short questionnaire to help us ascertain the areas of concern, in order for us to help you most effectively. Before undertaking the communication assessment, a thorough hearing test is completed, including medical history. In tinnitus associated with inner ear damage, and especially that due to noise, it seems reasonable to expect that deficits in inner ear function should be present at the same frequency as the tinnitus.
For the left ear (top), OAEs (the difference between the top and bottom trace) are excellent up to roughly 11,000 Hz.
There are, however, several likely sources, all of which are known to trigger or worsen tinnitus. When tinnitus is a symptom of another disorder, treating the disorder can help alleviate the tinnitus. This kind of tinnitus can be caused by abnormal blood flow in arteries or veins close to the inner ear, brain tumors or irregularities in brain structure. However it is important to note that these options do not work for everyone and do not work to the same degree for each individual patient. Balancing thyroid hormone, correcting anemia, and controlling cholesterol might be all that is required to reverse tinnitus. While some have argued that tinnitus and depression are linked, it is not so simple to think that depression alone leads to tinnitus. These medicines quiet electrical activity in the brain and can be helpful in quieting some of the signals that cause tinnitus. If there is a physical problem that is causing tinnitus and it can be reached and corrected surgically, surgery becomes the treatment of choice. In Meniere’s disease there is an excess of endolymph (fluid) in the vestibular system (the inner ear organ that helps us walk upright and maintain balance).
Since once of the root causes (or pathways, really) of tinnitus is abnormal electrical activity in the nerves going from the cochlea to the auditory cortex, scientists and doctors have tried to use electrical stimulation to override those signals.
Instead of stimulating the cochlea, a device is applied to the outside of the skull and stimulates brain tissue using strong magnetic oscillations. These tinnitus treatments include hearing aids, masking devices, and tinnitus feedback retraining.
While a hearing aid amplifies sounds that enter the ear, a tinnitus masking device creates noise of its own. This conjecture offers a possible for adding objective evidence to substantiate the existance of what would otherwise be an intrinsicially subjective phenomenon.
Most cases of tinnitus are subjective, but occasionally the tinnitus can be heard by an examiner. A person viewing it online may make one printout of the material and may use that printout only for his or her personal, non-commercial reference. Tinnitus can be intermittent or constant-with single or multiple tones-and its perceived volume can range from subtle to shattering.
Your Elkhart Audiologist, Sharon Hirstein, understands that tinnitus can negatively impact your life, family and work. Sure having tinnitus can be depressing, but only certain types of antidepressants work on tinnitus, specifically tricyclic antidepressants.


Sometimes these arteriovenous malformations, as they are called, are present at birth but more often they develop later in life.
In fact, the earliest reports of electrical stimulation of the ears for the treatment of tinnitus date back over a hundred years. The technology has been used to improve drug delivery and reduce auditory hallucinations, but may also be effective in treating tinnitus.
Since hearing and tinnitus are intimately related, it makes sense that treating deafness also helps treat tinnitus. Because tinnitus can be a single tone, at nearly any pitch, one really needs to quantify inner ear function at all frequencies.
This suggests that there was outer hair cell damage at the same location using an objective test as had already been localized using a subjective test (audiometry).
Otologic problems, especially hearing loss, are the most common causes of subjective tinnitus.

Before taking any medication, make sure that your prescribing physician is aware of your tinnitus, and discuss alternative medications that may be available. The best way to prevent tinnitus are to avoid those things that assault the ears namely prolonged exposure to loud noise, short exposures to extremely loud noise, and drugs that can hurt the ears.
A full medical checkup is a good place to start because a great number of potential causes will be checked and addressed if needed.
If depression was the sole cause, one would expect that better depression medicines like selective serotonin reuptake inhibitors (SSRIs) would also be the better tinnitus medicines. Also, this class of drugs can be habit-forming, which is why they are used with caution and weighed against their usefulness.
An acoustic neuroma is a benign growth around the nerve that carries electrical signals from the inner ear to the brain. While directly stimulating the auditory system has been reported to help 4 out of 5 patients, the tinnitus returns soon after the stimulation has stopped. Early research indicates that transcranial magnetic stimulation may reduce the symptom of tinnitus for up to six months at a time.
Improving hearing with a hearing aid does not always correct tinnitus, but it can be quite helpful to a number of patients with both hearing loss and tinnitus (about half).
Unfortanately, it is impractical to test hearing in a continuous fashion because each single frequency takes roughly a minute to test.
This technique might be useful for medico-legal situations where there is noise trauma and tinnitus. Common causes of conductive hearing loss include external ear infection, cerumen impaction, and middle ear effusion.
Epidemiologic data reveal that approximately one fourth of persons with tinnitus are discomforted by it, whereas the remaining three fourths experience the condition without significant symptoms.3Tinnitus takes different forms and has different classification proposals.
The area is certainly murky, scientifically, but antidepressant medications may be a tool to treat tinnitus in certain patients. Newer strategies for treating abnormal blood vessels include burning them or injecting them with sclerosing agents which causes the vessel to shrink and to die. Meniere’s surgery is not 100% effective at treating the primary disease or tinnitus, but it may be an option for some people.
It is not practical to use current methods of stimulation constantly—there would be no time for living life. Sensorineural hearing loss may be caused by exposure to excessive loud noise, presbycusis, ototoxic medications, or Meniere's disease. One classification system stresses distinctions between vibratory and nonvibratory types, while another system groups the different forms of tinnitus into subjective or objective classes.Vibratory tinnitus is caused by transmission to the cochlea of vibrations from adjacent tissues or organs.
Regular checkups can catch hormonal and metabolic problems in the early stages before they result in tinnitus. If the blood vessel that is causing the problem is an important one (like the jugular vein) destroying it is not a viable option.
Nonvibratory tinnitus is produced by biochemical changes in the nerve mechanism of hearing.Subjective tinnitus, which is more common, is heard only by the patient. Similar tissue growths at various places in and around the ear can cause tinnitus and can be cured surgically.
While these devices are primarily used to give the sense of hearing to the deaf, they do so by directly stimulating the cochlea.
Objective tinnitus can be heard through a stethoscope placed over head and neck structures near the patient's ear.The mechanism that produces tinnitus remains poorly understood. While it would be considered a rather bold clinical move, cochlear implants may be used to treat tinnitus in the future.
Objective tinnitus usually is caused by vascular abnormalities of the carotid artery or jugular venous systems. Tinnitus may originate at any location along the auditory pathway from the cochlear nucleus to the auditory cortex. Initial evaluation of tinnitus should include a thorough history, head and neck examination, and audiometric testing to identify an underlying etiology. Some leading theories include injured cochlear hair cells that discharge repetitively and stimulate auditory nerve fibers in a continuous cycle, spontaneous activity in individual auditory nerve fibers, hyperactivity of the auditory nuclei in the brain stem, or a reduction in the usual suppressive activity of the central auditory cortex on peripheral auditory nerve activity.4This article discusses the causes of subjective and objective tinnitus, and techniques used for evaluating tinnitus.


Unilateral or pulsatile tinnitus may be caused by more serious pathology and typically merits specialized audiometric testing and radiologic studies.
In patients who are discomforted by tinnitus and have no remediable cause, auditory masking may provide some relief. A thorough history and physical examination should be directed at ruling out serious disorders.
Conductive hearing loss is caused by the inhibition of sound transmission to the inner ear. The most common etiologic factors are noise-induced hearing loss (NIHL), or the progressive loss of acuity that occurs with advancing age (presbycusis).NIHL is the most common type of acquired hearing loss.
Screening for exposure to excessive or loud noises can be performed during routine health maintenance visits.11 Continued counseling about the risk of hearing loss is warranted if the patient is exposed to damaging sounds. Patients should be encouraged to avoid long-term exposure to hazardous noises and to use hearing protection when necessary.
It is continuous and less disturbing than the tinnitus of Meniere's disease.14Ototoxic medications or substances are another common cause of bilateral tinnitus. Currently, almost every major group of medication includes one or more compounds with ototoxic properties (Table 2).2,10,15 Ototoxicity may affect hair cells, the eighth cranial nerve, or their central nervous connections. Temporomandibular joint disorder has been associated with vertigo and tinnitus, although the exact mechanism is unclear.Various metabolic abnormalities may be associated with tinnitus. These abnormalities include hypothyroidism, hyperthyroidism, hyperlipidemia, anemia, and vitamin B12 or zinc deficiency.Many patients with tinnitus exhibit signs of psychologic disorders.
Although tinnitus may be a contributing factor to the development of depression, the common association of tinnitus and depression may be the result when depressed patients, particularly those with sleep disturbances, focus and dwell on their tinnitus more than patients who are without an underlying psychologic disorder.OBJECTIVE TINNITUSObjective tinnitus is rare.
Patients with objective tinnitus typically have a vascular abnormality, neurologic disease, or eustachian tube dysfunction.4Patients with vascular abnormalities complain of pulsatile tinnitus.
Arterial bruits may be transmitted to the ear from arterial vessels near the temporal bone. The petrous carotid system is the most common source.2 Patients experience worsening of symptoms at night and usually do not have other otologic complaints.
Venous hums may be heard in patients with hypertension or abnormally high placement of the jugular bulb. This type of tinnitus is a soft, low-pitched venous hum, which can be altered by head position, activity, or pressure over the jugular vein.4Congenital arteriovenous shunts are usually asymptomatic, while the acquired type often are associated with pulsatile tinnitus.
Glomus tumor is a vascular neoplasm arising from the paraganglia around the carotid bifurcation, the jugular bulb, or the tympanic arteries. The symptoms may disappear with Valsalva's maneuver or when the patient lies down with the head in a dependent position.Evaluation of TinnitusHISTORYThe evaluation of a patient with tinnitus begins by taking a thorough history. Precipitous onset can be linked to excessive or loud noise exposure or head trauma.LocationUnilateral tinnitus can be caused by cerumen impaction, otitis externa, and otitis media. Tinnitus associated with unilateral sensorineural hearing loss is the hallmark of acoustic neuroma.PatternContinuous tinnitus accompanies hearing loss. The external canal and tympanic membrane should be inspected for signs of cerumen impaction, perforation, or infection.
The cranial nerves should be examined for evidence of brain-stem damage or hearing loss.9 Auscultation over the neck, periauricular area, orbits, and mastoid should be performed. Tinnitus of venous origin can be suppressed by compression of the ipsilateral jugular vein.Specific testing for sensorineural or conductive hearing loss is the next part of the examination. In the Weber test, the tuning fork is struck and placed on the midline of the forehead, the nasal bridge, or the chin. The sound lateralizes to the opposite ear in patients with a sensorineural hearing loss, but to the same side in those with a conductive hearing loss.
Patients with normal hearing or equal deafness in both ears hear the sound at the same level in both ears.In the Rinne test, the tuning fork is placed against the mastoid process to measure the conduction of sound by bone. When the sound can no longer be heard, the tuning fork is placed in front of the auditory canal to test air conduction. If air conduction is greater than bone conduction, hearing is normal or sensorineural hearing loss is present. A formal audiogram establishes a base from which to pursue more advanced diagnostic testing. Pure tone testing primarily tests the function of the peripheral portion of the hearing apparatus. Sound must be interpreted in the central nervous system before it can be useful to the patient. Further investigation should be dictated by the index of suspicion created by the history, physical examination, and audiometric profile (Figure 1).
Patients with unilateral or pulsatile tinnitus are more likely to have serious underlying disease and typically merit referral to an otolaryngologist.2,5 A full clinical evaluation should precede radiologic studies.
Because pulsatile tinnitus suggests a vascular abnormality, the preferred imaging study is contrast-enhanced computed tomography (CT) or magnetic resonance imaging (MRI) of the brain21 (Figure 2).
