Ear drum ringing may be related to tympanic ventricular somatotoma, intracranial vascular dysplasia or anatomical abnormalities, atherosclerosis and other diseases.
1. tympanic ventricular somatotumor: a kind of nonophilic paraganglioma, the lesion originates from the tympanic ventricle, the early stage is unilateral tinnitus, the tinnitus is consistent with the pulse.
2. Craniocervical intravascular arterial dysplasia or anatomical abnormality: if the internal carotid artery is dysplasia in embryonic period, and the intersection of vertical and horizontal segments adjacent to the base of the skull is dislocated, and the blood vessel is narrowed, tinnitus can be caused by blood flow disorder in this place, or blood flow of pharyngeal artery is increased, which will cause tinnitus of pulsatile ear. Jugular vein ball high, can also cause pulsatile tinnitus.
3. Atherosclerosis: hypertension, hyperlipidemia, diabetes mellitus, cerebrovascular accident or transient cerebral ischemia can be caused by localized ischemia, arterial stenosis caused by blood flow disorders produced by the ringing through the cochlea bone conduction to the cochlea, and synchronized with the pulse tinnitus pulsatile tinnitus, the ears were drums ringing characteristics.
When the ear drum ringing, can actively seek medical systematic examination, clear diagnosis and cause.
