It is possible that the most common cause of pulsatile tinnitus is sigmoid sinus diverticulum and dehiscence, which can be collectively referred to as sinus wall abnormalities or SSWA. The sigmoid sinus is a blood carrying channel on the side of the brain that receives blood from veins within the brain. The blood eventually exits through the internal jugular vein. Sigmoid sinus diverticulum refers to the formation of small sac-like pouches (diverticula) that protrude through the wall of the sigmoid sinus into the mastoid bone behind the ear. Dehiscence refers to absence of part of the bone that surrounds the sigmoid sinus in the mastoid. It is unknown whether these conditions represent different parts of one disease process or spectrum, or whether they are two distinct conditions. These abnormalities cause pressure, blood flow, and noise changes within the sigmoid sinus, which ultimately results in pulsatile tinnitus. Narrowing of the blood vessel that leads into the sigmoid sinus, known as the transverse sinus, has also been associated with pulsatile tinnitus.
Tinnitus can be extremely disturbing to people who have it. In many cases it is not a serious health problem, but rather a nuisance that may go away. However, some people with tinnitus may require medical or surgical treatment. Sixteen million Americans seek medical treatment each year for tinnitus, and about one-quarter of those experience it so severely it interferes with their daily activities.
Most people develop tinnitus as a symptom of hearing loss. When you lose hearing, your brain undergoes changes in the way it processes sound frequencies. A hearing aid is a small electronic device that uses a microphone, amplifier, and speaker to increase the volume of external noises. This can mollify neuroplastic changes in the brain’s ability to process sound.
A large, 2014 study of almost 14,000 people found obstructive sleep apnea was linked to significantly higher rates of hearing impairment and hearing loss. Scientists think one reason for this is changes to blood flow to the ear that result in inflammation. (We know that sleep apnea causes changes to circulation and weakens blood flow to some areas of the body, including the brain.) A related factor? People with sleep apnea are at greater risk for high blood pressure, and high blood pressure can exacerbate hearing loss, according to research.
With respect to incidence (the table above is about prevalence), Martinez et al (2015) reported that there were 5.4 new cases of tinnitus per 10,000 person-years in England. We don't find this statistic much use as tinnitus is highly prevalent in otherwise normal persons. It seems to us that their study is more about how many persons with tinnitus were detected by the health care system -- and that it is more a study of England's health care system than of tinnitus.
Seek out cognitive-behavioral therapy. Cognitive behavioral therapy, or CBT, involves working with a clinician (or independently, with a clinically-developed self-treatment program) to re-frame negative thoughts, emotions, and behaviors. CBT is effective with a wide range of physical and mental health conditions, including stress, anxiety, and depression. CBT is also highly effective in treating insomnia and other sleep problems. And research shows CBT can help improve the management of tinnitus.
If cerumen (more commonly known as ear wax) accumulates in your ear canal, it can diminish your ability to hear. Your auditory system may overcompensate for the loss, fabricating noises that do not exist. Your audiologist can safely remove the buildup, and in most cases, this will immediately alleviate your tinnitus. However, sometimes ear wax buildup causes permanent damage, resulting in chronic tinnitus.
Tinnitus is not a disease in and of itself, but rather a symptom of some other underlying health condition. In most cases, tinnitus is a sensorineural reaction in the brain to damage in the ear and auditory system. While tinnitus is often associated with hearing loss, there are roughly 200 different health disorders that can generate tinnitus as a symptom. Below is a list of some of the most commonly reported catalysts for tinnitus.
There's no known cure for tinnitus. Current treatments generally involve masking the sound or learning to ignore it. A research team led by Dr. Michael Kilgard at the University of Texas at Dallas and Dr. Navzer Engineer at MicroTransponder, Inc. set out to see if they could develop a way to reverse tinnitus by essentially resetting the brain's auditory system. Their work was funded in part by NIH’s National Institute on Deafness and Other Communication Disorders (NIDCD).
Tinnitus also could be the result of neural circuits thrown out of balance when damage in the inner ear changes signaling activity in the auditory cortex, the part of the brain that processes sound. Or it could be the result of abnormal interactions between neural circuits. The neural circuits involved in hearing aren’t solely dedicated to processing sound. They also communicate with other parts of the brain, such as the limbic region, which regulates mood and emotion.
Physical exam: Physical examination will focus on the head and neck, and especially the ears, including the auditory canals and tympanic membranes. Since the sense of hearing is conducted through one of the cranial nerves (the short nerves that lead directly from the brain to the face, head and neck), a careful neurologic exam also may be performed. Weakness or numbness in the face, mouth, and neck may be associated with a tumor or other structural abnormality pressing on a nerve. The healthcare professional may listen to the flow in the carotid arteries in the neck for an abnormal sound (bruit), since carotid artery stenosis (narrowing of the artery) can transmit a sound to the ear that may cause tinnitus.
Psychological research has looked at the tinnitus distress reaction (TDR) to account for differences in tinnitus severity. These findings suggest that at the initial perception of tinnitus, conditioning links tinnitus with negative emotions, such as fear and anxiety from unpleasant stimuli at the time. This enhances activity in the limbic system and autonomic nervous system, thus increasing tinnitus awareness and annoyance.
Repetitive transcranial magnetic stimulation (rTMS). This technique, which uses a small device placed on the scalp to generate short magnetic pulses, is already being used to normalize electrical activity in the brains of people with epilepsy. Preliminary trials of rTMS in humans, funded by the NIDCD, are helping researchers pinpoint the best places in the brain to stimulate in order to suppress tinnitus. Researchers are also looking for ways to identify which people are most likely to respond well to stimulation devices.
Tinnitus – a sound in the head with no external source – is not a disease; it is a symptom that can be triggered by a variety of different health conditions. So what causes tinnitus? Common sources include hearing loss, ear wax buildup, ototoxic medications, and ear bone changes. No matter what the cause, the condition interrupts the transmission of sound from the ear to the brain. Some part of the hearing system is involved as well, whether the outer, middle, or inner ear.
Schecklmann et al (2014) suggested that tinnitus is associated with alterations in motor cortex excitability, by pooling several studies, and reported that there are differences in intracortical inhibition, intra-cortical facilitation, and cortical silent period. We doubt that this means that motor cortex excitability causes tinnitus, but rather we suspect that these findings reflect features of brain organization that may predispose certain persons to develop tinnitus over someone else.
Tinnitus patients with a TMJ disorder will experience pain in the face and/or jaw, limited ability to move the jaw, and regular popping sounds while chewing or talking. A dentist, craniofacial surgeon, or other oral health professional can appropriately diagnose and often fix TMJ issues. In many scenarios, fixing the TMJ disorder will alleviate tinnitus symptoms.
Over the last 40 years of treating patients suffering from tinnitus, there’s been one over the counter medication that has shown the greatest promise. While it doesn’t provide relief for everyone, I continue to see an 87% efficacy rate in my patients. The treatment, which does not require a prescription, is known as Tinnitus Control and is available online at http://www.tinnituscontrol.com
Microvascular compression may sometimes cause tinnitus. According to Levine (2006) the quality is similar to a "typewriter", and it is fully suppressed by carbamazepine. It seems to us that response to carbamazepine is not a reliable indicator of microvascular compression as this drug stabilizes nerves and lowers serum sodium. Nevertheless, this quality of tinnitus probably justifies a trial of oxcarbamazine (a less toxic version of carbamazepine).
Tinnitus is associated with a high level of emotional stress. Depression, anxiety, and insomnia are not uncommon in people with tinnitus. Cognitive behavioral therapy (CBT) is a type of talk therapy that helps people with tinnitus learn to live with their condition. Rather than reducing the sound itself, CBT teaches you how to accept it. The goal is to improve your quality of life and prevent tinnitus from driving you crazy.
Ringing in your ears, hissing, buzzing, roaring - tinnitus can take many forms. The bothersome and uncomfortable noise in your ear varies from one tinnitus sufferer to another. So does the impact of tinnitus on people's lives. Some get used to the never-ending noise in the ear with relative ease, while others are driven to despair. Many ask can tinnitus be cured? Is there a tinnitus remedy?
Ear protection can mitigate the negative effects of loud noises and prevent the exacerbation of tinnitus. This is especially important if you work in a loud environment or regularly visit loud places, like shooting ranges, concerts, and clubs. Wearing custom earplugs or special earmuffs can go a long way toward preventing your tinnitus from worsening.
The degree of loudness or annoyance caused by tinnitus varies greatly from one individual to another. Loudness and annoyance do not always covary. An individual with loud tinnitus may not be troubled, while an individual with soft tinnitus may be debilitated. Most individuals with subjective tinnitus have hearing loss that shows up in a standard clinical audiogram. Tinnitus can sometimes worsen or sometimes improve over time.
Tinnitus remains a symptom that affects the lives of millions of people. Research is directed not only at its treatment, but also at understanding why it occurs. Research by doctors at the University at Buffalo, The State University of New York, Dalhousie University (Canada), and Southeast China University have published research using electrophysiology and functional MRI to better understand what parts of the brain are involved in hearing and the production of tinnitus. Their research has found that much larger areas of the brain are involved with the process of hearing than previously believed, which may help direct future diagnostic and therapeutic options.
White Noise Machines. These devices do a great job of simulating the sound of everything from ocean waves, to rain, to a thunder storm, to a crackling fire to an oscillating fan to just plain old static. The result is that your brain focuses on the sounds around you instead of the ringing in your head. You can even download apps on your iPhone that do the same thing so that you can always have a noise machine with you wherever you go. The constant background noise can not only bring back nostalgic feelings of joy, if you used to site around a crackling fire on holidays with your family, but also allow you to forget about your tinnitus.
Some people experience a sound that beats in time with their pulse, known as pulsatile tinnitus or vascular tinnitus. Pulsatile tinnitus is usually objective in nature, resulting from altered blood flow, increased blood turbulence near the ear, such as from atherosclerosis or venous hum, but it can also arise as a subjective phenomenon from an increased awareness of blood flow in the ear. Rarely, pulsatile tinnitus may be a symptom of potentially life-threatening conditions such as carotid artery aneurysm or carotid artery dissection. Pulsatile tinnitus may also indicate vasculitis, or more specifically, giant cell arteritis. Pulsatile tinnitus may also be an indication of idiopathic intracranial hypertension. Pulsatile tinnitus can be a symptom of intracranial vascular abnormalities and should be evaluated for irregular noises of blood flow (bruits).
Vitamin Supplements. Vitamin supplements, like Lipo-Flavonoid Plus, contain the vitamins that some studies have shown to be beneficial to inner ear health. These include Vitamin C, B-1, B-2, B-6, B-12, zinc, niacin and calcium. And while I am a proponent of vitamins, I advise my patients to take a regular OTC multivitamin that costs $15, versus Lipo-Flavonoid Plus, which has the same ingredients, but costs up to $90 for the same number of pills, just because it’s packaged and marketed to people that suffer from tinnitus.
FACT: Many people with tinnitus will also have a hearing loss. In fact, a recent French study showed that of 123 people with tinnitus surveyed only one did not have hearing loss. The British Tinnitus Association estimates that 90 percent of people with tinnitus also have a hearing loss. Moreover, research says that those who don’t may have a “hidden hearing loss.”
As their name suggests, maskers conceal tinnitus through other sounds. They look similar to hearing aids, but they won’t enhance your hearing. In this way, they’re like band-aids, covering up the problem instead of actually solving it. In addition, some people find maskers frustrating, because they can soften important sounds, like speech. We do not recommend maskers for long-term use as they do not work in re-wiring the brain.
Masking. Masking devices, worn like hearing aids, generate low-level white noise (a high-pitched hiss, for example) that can reduce the perception of tinnitus and sometimes also produce residual inhibition — less noticeable tinnitus for a short time after the masker is turned off. A specialized device isn't always necessary for masking; often, playing music or having a radio, fan, or white-noise machine on in the background is enough. Although there's not enough evidence from randomized trials to draw any conclusions about the effectiveness of masking, hearing experts often recommend a trial of simple masking strategies (such as setting a radio at low volume between stations) before they turn to more expensive options.
At Sound Relief Hearing Center, we utilize a variety of evidence-based tinnitus treatment options. Most audiologists only offer one solution, hearing aids, which are ineffective in many cases. To treat each unique case of tinnitus, we utilize a variety of innovative technologies and therapies, including Tinnitus Retraining Therapy (TRT).

If you’re worried that you won’t ever escape the ringing in your ears, check out our page Tinnitus Success Stories. Finally, follow our Tips from Tinnitus Experts to avoid exacerbating the problem.
Widex employs fractal tone technology, so that the sounds you hear are predictable but not repeating. Your audiologist can choose between an assortment of “musical tones” known as “Zen styles,” which are random and chime-like. Your audiologist can adjust the tones’ pitch, tempo, and volume. If employed correctly, Widex Zen Therapy can help re-wire your brain and make your tinnitus less noticeable.
Meniere’s disease isn’t directly connected to tinnitus, but people with Meniere’s often experience it, at least temporarily. Meniere's disease is an inner ear disease that typically only affects one ear. This disease can cause pressure or pain in the ear, severe cases of dizziness or vertigo and a ringing or roaring tinnitus. While Meniere’s isn’t fully understood, it appears that several relief options for tinnitus can also help with this disease. Patients are often advised to reduce stress and lower their consumption of caffeine and sodium.
