![]() ResultsĬochlear nerve activity in patients with tinnitus was increased with a shorter latency (p = 0.016) and stronger ECD strength (p = 0.028) compared with patients without tinnitus. We compared the difference in the latency and the ratio of the equivalent current dipole (ECD) strength between the ipsilateral and contralateral sides of the spasm and tinnitus. We used magnetoencephalography (MEG) to estimate the activity of the cochlear nerve in patients with and without tinnitus on the ipsilateral side. Participants were 29 subjects who presented with hemifacial spasm and neuroradiological evidence of vascular compression of the cranial (facial/cochlear) nerve. If it doesn't go away on its own after a few weeks or becomes really bothersome, talk with your doctor about it.Traditionally, tinnitus accompanied by hemifacial spasm has been considered a type of hyperactive neurovascular compression syndrome that is similar to hemifacial spasm alone because of the anatomically close relationship between the facial nerve and cochlear nerve as well as the hyperactive clinical nature. Most of the time, pulsatile tinnitus is nothing to worry about. If I heard a bruit (BROO-ee) - the unusual sound that blood makes when it rushes past an obstruction - in one or both carotid arteries, I would suggest you have a test to look for a narrowing in the carotid arteries or other malformations. If I did not find any obvious cause for your symptoms, I would likely recommend some additional testing, including a hearing test. I would also use a stethoscope to listen to the blood flow through the arteries in your neck. If you were my patient, I would take a careful history (a patient's story often holds important clues), and then examine your ears. These include a blood vessel with a weakened, bulging patch (aneurysm), an abnormal connection between an artery and vein (arteriovenous malformation), twisted arteries, or a benign blood vessel tumor (glomus tumor) behind the eardrum. High blood pressure. When blood pressure is high, blood flow through the carotid artery is more likely to be turbulent and thus cause a pulsating sound.īlood vessel disorders. A variety of malformations and disorders are occasionally the source of pulsatile tinnitus. A conductive hearing loss also makes it easier to hear blood flowing through two large vessels that travel through each ear, the carotid artery and the jugular vein, which circulate blood to and from the brain.Ĭarotid artery disease. The accumulation of fatty plaque inside the carotid arteries can create the kind of turbulent blood flow that resounds as pulsatile tinnitus. This type of hearing loss intensifies internal head noises - sounds like breathing, chewing, and blood flowing through the ear. Sometimes it is caused by problems with the ossicles (small bones involved in hearing). The most common causes of pulsatile tinnitus include the following:Ĭonductive hearing loss. This is usually caused by an infection or inflammation of the middle ear or the accumulation of fluid there. The sound is the result of turbulent flow in blood vessels in the neck or head. Most people with pulsatile tinnitus hear the sound in one ear, though some hear it in both. It is a type of rhythmic thumping, pulsing, throbbing, or whooshing only you can hear that is often in time with the heartbeat. My health is good, and I was told after a recent cardiac workup that my heart was "perfect." Should I be worried that I can hear the rhythmic pattern of my heart from inside my left ear?Ī. What you describe sounds like pulsatile tinnitus (pronounced TIN-nih-tus or tin-NITE-us). ![]() I hear it most clearly when I am in bed or sitting quietly. ![]() Q. One morning last week I woke up hearing my heartbeat in my left ear. If you hear "heartbeat" thumping in your ear, it may be pulsatile tinnitus ![]()

![]() This query can run slowly if you have a large number of deadlocks, it also is hard to get an overall of what is going on if you have a large number of deadlocks.
