Pulsatile tinnitus worse when lying down, tinnitus help - For You

Tinnitus (pronounced ti-ni-tis), or ringing in the ears, is the sensation of hearing ringing, buzzing, hissing, chirping, whistling, or other sounds. Although tinnitus is often associated with hearing loss, it does not cause the loss, nor does a hearing loss cause tinnitus. Some instances of tinnitus are caused by infections or blockages in the ear, and the tinnitus can disappear once the underlying cause is treated. Certain drugs -- most notably aspirin, several types of antibiotics, anti-inflammatories, sedatives, and antidepressants, as well as quinine medications; tinnitus is cited as a potential side effect for about 200 prescription and nonprescription drugs.
Tinnitus can worsen in some people if they drink alcohol, smoke cigarettes, drink caffeinated beverages, or eat certain foods.
Tinnitus, (pronounced tih-NIGHT-us or TIN-ih-tus) is a ringing, swishing, or other type of noise that seems to originate in the ear or head. Trust me, very many artists have tinnitus and hearing loss, just majority of them would rather not talk about it.

Most cases of tinnitus are subjective, but occasionally the tinnitus can be heard by an examiner.
In fact, some people with tinnitus experience no difficulty hearing, and in a few cases they even become so acutely sensitive to sound (hyperacusis) that they must take steps to muffle or mask external noises.
For reasons not yet entirely clear to researchers, stress and fatigue seem to worsen tinnitus. But ringing in the ears that does not get better or go away is an ear condition called tinnitus.
Tinnitus is a condition that occurs when there is a malfunction in the inner ear that hinders its connection to the brain.
Tinnitus is any kind of persistent noise that doesn’t have any external source, and seems to originate in the ear or head. Tinnitus is a term that describes any sound a person can hear from inside their body rather than from an outside source. Otologic problems, especially hearing loss, are the most common causes of subjective tinnitus.

It is often worse when background noise is low, so you may be most aware of it at night when you're trying to fall asleep in a quiet room. In severe cases, however, tinnitus can cause people to have difficulty concentrating and sleeping. It may eventually interfere with work and personal relationships, resulting in psychological distress. Carpenters, pilots, rock musicians, street-repair workers, and landscapers are among those whose jobs put them at risk, as are people who work with chain saws, guns, or other loud devices or who repeatedly listen to loud music. The most common cause of tinnitus is hearing loss that occurs with aging, but it can also be caused by living or working around loud noises.
Objective tinnitus usually is caused by vascular abnormalities of the carotid artery or jugular venous systems. Initial evaluation of tinnitus should include a thorough history, head and neck examination, and audiometric testing to identify an underlying etiology.
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.
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. 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.
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. 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.
Tinnitus may originate at any location along the auditory pathway from the cochlear nucleus to the auditory cortex. 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. 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.


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. 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. 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. 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. 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. When the sound can no longer be heard, the tuning fork is placed in front of the auditory canal to test air conduction. 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).
