The sound of blood flow can be heard in the ear mostly refers to pulsatile tinnitus, which may be related to jugular vein globe tumor or tympanic bulboma, dural arteriovenous fistula, congenital vascular malformation and other diseases.
1. Jugular vein bulboma or tympanic bulboma: it is the most common tumor in jugular venous foramen region, originating from paraganglionic cells of chemoreceptors in jugular vein bulb, the tumor is rich in blood vessels and grows slowly, but it is invasive, and it grows from jugular vein bulb to the periphery to invade the middle ear and mastoid process. One side of pulsatile tinnitus, the rhythm is consistent with the heart rhythm.
2. Dural arteriovenous fistula: may be secondary to the dural venous sinus thrombosis or sinus cavity closure, fistula tract by the sinus wall of the rich network of small arteries and venous sinus or small veins between the formation of many tiny traffic branch. Because of the lesion of the venous sinus directly accept arterial blood flow, and cause pulsatile tinnitus.
3. Congenital vascular malformation: such as embryonic internal carotid artery dysplasia, its vertical and horizontal segments adjacent to the base of the skull at the intersection of the displacement, vascular stenosis, can be due to blood flow disorders in this place, or pharyngeal ascending artery blood flow increases, causing pulsatile tinnitus.
The ear can hear the sound of blood flow may also be related to myoclonus, neuritis and other diseases, it is recommended to actively consult a doctor for a systematic examination, in order to clarify the cause of the disease and diagnosis, and cooperate with the doctor for active treatment.
