What are the causes of pulsatile tinnitus?

Pulsatile tinnitus is caused by blood vessels or muscles in the head and neck, and is perceived by the transmission to the cochlea after passing through the bones, blood vessels, and blood flow. Vascular pulsatile tinnitus is more common, including jugular spheroid tumor, intracranial and extracranial vascular malformations, dural arteriovenous fistula, atherosclerosis, etc.; Nonvascular pulsatile tinnitus is associated with myoclonus in the head and neck,** including palatine myoclonus, stapedius muscle, or tensor tympanic myoclonus. In addition, strenuous exercise, emotional agitation, etc., may also cause pulsatile tinnitus.

Pulsatile tinnitus, because of tinnitus, it is also very much, there is subjective tinnitus, there is objective tinnitus, subjective tinnitus refers to the patient himself feels that he has tinnitus, this one or both ears, this is his own subjective symptoms. When we talk about objective tinnitus, we mean that not only the patient can hear it, but if you, the doctor or examiner, you can hear it if you get closer, for example, if you get closer to your ear or you can hear it with a stethoscope, it is talking about the objective tinnitus, and we are talking about the objective tinnitus. Then this pulsatile tinnitus belongs to one of the objective tinnitus, often because of the abnormality of the blood vessel, caused, we most often find the sigmoid sinus, such as the tympanic wall of the sigmoid sinus, this has this defect or has a weak place or the sigmoid sinus forms a diverticulum, then it can cause pulsatile tinnitus, and there is a high jugular venous ball, if the jugular venous ball is relatively high, it will also cause this pulsatile tinnitus, the so-called pulsatile tinnitus is that he feels this tinnitusIt is consistent with his pulse and heartbeat, that is, when the heart beats, it rings in his ears, which is called pulsatile tinnitus.

Pulsatile tinnitus, common clinical causes: 1. It is muscle-derived; Second, it is vascular-derived, that is, the pulse of the blood vessels in the neck around the ear, after excessive exaggerated conduction, causing a kind of pulsatile tinnitus subjectively, this kind of tinnitus is staged, and the rhythm of the tinnitus and the pulse and heartbeat are consistent. It can be improved by taking adequate rest, controlling blood pressure, and adjusting the work and rest routine.

Cervical angiography can also be done to rule out whether there is a small probability of events, such as vascular malformation, arteriovenous fistula, etc., and most vascular pulsatile tinnitus does not require special **. In addition, the middle ear cavity generally has two muscles, one is the branch of the stapedius muscle, and this is the tensor muscle of the tympanic semicircular canal, which are innervated by the branches of the facial nerve and the trigeminal nerve respectively. If the facial and trigeminal nerves undergo involuntary firing activity, it can cause involuntary twitching of the muscles.

It is a common facial and mouth twitching, and facial muscle spasm is not artificially controllable. This condition is divided into primary and secondary, and most of them do not require special treatment.

Pulsatile tinnitus is the sound of tinnitus in the ear that is basically the same as the pulse rate. The main cause of pulsatile tinnitus is vascular tinnitus, in which the pulse of the blood vessels in some parts of the ear, including bone defects in front of the sigmoid sinus, internal carotid artery body aneurysm, and lesions of blood vessels in the ear, blockage of blood vessels, bone weakness or defects between blood vessels and the inner ear, is transmitted to the inner ear, resulting in pulsatile tinnitus. When a patient has pulsatile tinnitus, the doctor can make a differential diagnosis and press the blood vessels in the corresponding area, if the tinnitus disappears, it may be pulsatile tinnitus.

Vascular pulsatile tinnitus is a condition secondary to vascular lesions, and arterial and venous disease is the main cause of vascular pulsatile tinnitus:

Arterial diseases: mainly include carotid atherosclerosis, internal carotid artery tortuosis, intracranial vascular malformation, vascular stenosis disease, arteriovenous fistula, anemia, carotid artery dissection, aneurysm, otosclerosis, hypertension, PAGOT disease, etc.

Venous diseases: mainly include benign intracranial hypertension syndrome, sigmoid diverticulum, tympanogloma, jugular globuloma, facial nerve hemangioma, etc.

Pathological tinnitus is generally related to the following factors: 1. Symptoms of high blood pressure, high blood pressure, arteriosclerosis, and stiff and twisted blood vessels will cause arterial vortex phenomenon, which will cause pulsatile tinnitus. 2. Caused by an aneurysm in an artery, or an arteriovenous fistula, most of the time caused by a high jugular spheroid aneurysm.

Among them, the mastoid process is often characterized by venous malformation, and the jugular bulb can cause obvious active tinnitus, which will be relieved when the jugular vein on the affected side is compressed. Therefore, if there is pulsatile tinnitus, we need to observe whether it is synchronized with the pulse, go to the hospital in time, ask a doctor to diagnose, and if necessary, we can perform imaging tests to clarify the cause of the tinnitus, so as to determine what kind of approach to take**.

Vascular disease.

Vascular disease most commonly causes pulsatile tinnitus. For example, the arteries near the temporal part of the ear may transmit the sound of turbulent blood, and the carotid artery system is also a common sound**. Patients with benign intracranial hypertension, sigmoid diverticulum, or significant jugular bulb may hear venous humming.

Tinnitus caused by hearing loss.

Hearing loss associated with ageing, known as presbycusis, usually begins around the age of 60.

Long-term exposure to high-decibel noise, or prolonged exposure to noisy environments, can also damage a person's auditory system and lead to hearing loss, such as at large entertainment events or violent chainsaws.

In the case of hearing loss, the brain is unable to accept certain frequencies of sound and the brain begins to adapt, and tinnitus may be a way for the brain to fill this gap.

There are many reasons for fighting tinnitus, some of them are caused by pathological reasons, and some are caused by physiological reasons, generally pathological reasons, such as high blood pressure, arteriosclerosis, and symptoms of stiff and twisted blood vessels, which will cause arterial vortex phenomenon, so it will cause fighting tinnitus.

Pulsatile tinnitus: Tinnitus is about the same frequency as the pulse sound. The main cause of pulsatile tinnitus is tubular tinnitus. Some parts of the ear include sigmoid anterior bone defect, internal carotid artery body aneurysm, intraauricular canal change, blockage between the canal and the inner ear, etc.
