![]() In this condition, also called idiopathic intracranial hypertension, you experience elevated pressure not from your blood but from the cerebrospinal fluid that bathes your brain and spine. It’s good to get your blood pressure tested as part of your routine physical. High blood pressure is very common, especially in people who are overweight or obese. Not only is the pressure of blood moving through your nearby blood vessels higher, but the increased pressure might lead to a turbulent flow, which causes it to make more noise. Sometimes, hearing your heartbeat in your ears might be related to having high blood pressure (hypertension). Other sources argue that it’s a “very rare” cause of pulsatile tinnitus. Some sources argue that it is a very common cause, accounting for up to 25% of all cases of pulsatile tinnitus (arguably the most common cause). There is disagreement about how common this is. This inefficient flow creates elevated pressure, which then translates into pulsatile tinnitus. Sometimes blood that is supposed to flow near the ear gets diverted so that it flows in certain ways. Talking to your Columbia otolaryngologist can help you distinguish the causes of hearing loss. Some of these causes are easily remedied, but others require surgery or other invasive procedures to treat. There are many potential causes of conductive hearing loss, including earwax buildup, infection, a foreign object in the ear canal, a noncancerous tumor, or fusing of the bones of the middle ear. In addition to hearing your heartbeat in your ears, you likely also experience magnification of breathing and chewing. As a result, the sounds from within your head sound louder. ![]() Conductive Hearing LossĬonductive hearing loss is when something blocks your hearing from outside your body. However, here are some of the most common causes of pulsatile tinnitus to consider as you make an appointment with your primary care physician and/or an otolaryngologist in Columbia. ![]() ![]() It can sometimes be hard to distinguish among these potential causes to get a good diagnosis. Since this is in general not a comfortable position to be in, this condition can be treated by placing a stent across the compression and thereby propping the sigmoid sinus open.As with other types of tinnitus ( commonly known as ringing in your ears), pulsatile tinnitus can have many potential causes. If that is the case, the person usually only gets pulsatile tinnitus on one side, and not in both ears, and if the head turns to the side of the noise, by turning the chin to the shoulder, the jugular vein gets compressed and the noise goes away. If there is a compression of that sinus, then the turbulence can cause pulsatile tinnitus. The sigmoid sinus is a large vein that runs behind the ear and connects to the jugular vein in the neck. Those veins are quite big and run in the bone hence doctors refer to them as sinus. ![]() Turbulent flow can also occur when there is a narrowing in one of the veins that are carrying blood from the head back to the heart. High blood pressure can worsen the noise, and an ultrasound of the neck can diagnose this condition. Those narrowings typically involve the carotid artery in the neck. This flow then becomes noisy in the same way that a smoothly running river will become noisier at a set of a waterfall. If the inside of a blood vessel becomes irregular due to atherosclerosis (hardening of the arteries) or other injury to the arteries such as a dissection, the blood flow will become turbulent rather than smooth when squeezing through that irregularity. ![]()
