Left ear inside like pulse beating may be related to ear pressure, jugular vein bulboma, jugular vein bulb elevation, intracranial and extracranial vascular malformation, arteriovenous fistula and other reasons.
1. Ear pressure: sometimes when lying on the side of the left ear pressure, there will be left ear inside the feeling like a pulse, adjust the position can be improved.
2. Jugular vein bulboma: this disease is a kind of hemangioma-like tumor originated from chemoreceptors, most of the jugular vein bulboma originated from the top of jugular vein bulb, and a few of them occurred in the tympanic chamber. It is characterized by unilateral pulsatile tinnitus, mild conductive deafness and a feeling of stuffiness in the ear, and the tinnitus is consistent with the pulse.
3. High jugular venous bulb: some patients’ left jugular venous bulb is deformed and mutated, protruding into the tympanic chamber, when it is higher than the bottom of the external auditory canal, or even higher than the bottom of the cochlea, and the condition of the surface of the bone is thin or lack of, the vascular pulsation sound can be transmitted to the inner ear, and the feeling of the inside of the left ear is like the sound of pulsation.
4. left intracranial and extracranial vascular malformations, arteriovenous fistula: congenital vascular malformations such as embryonic hypoplasia of the internal carotid artery, or acquired vascular malformations such as diverticulum of the ethmoid sinus or bone wall defects; the formation of arteriovenous fistula, which will lead to tinnitus in the left ear pulsation, feeling like a pulse in the left ear.
When the left ear inside like a pulse beat happens, you can actively seek medical treatment, systematic examination to clarify the diagnosis and cause of the disease.
