Ear diseases External ear diseases such as cerumen embolism, foreign bodies, tumors, fungal diseases and inflammatory swelling; middle ear diseases such as middle ear inflammation, negative pressure in the tympanic chamber, adhesion or fixation of the auditory chain, abnormal opening of the eustachian tube; inner ear diseases such as sudden deafness, senile deafness, noise deafness, Meniere’s disease, and auditory neuroma can cause tinnitus. Cardiovascular diseases Tinnitus is pulsatile and often coincides with the heartbeat or pulse. Hypertension, anemia, and abnormalities of the blood vessels in the head and neck or skull base can all produce pulsatile tinnitus. Myogenic disorders Tinnitus is mostly a “click, click” sound. It is associated with spasmodic contraction of the palatopharyngeal muscle, tympanic membrane tensor muscle, and stapedius muscle. Other conditions such as mental stress, overexertion, drug reactions, hyperthyroidism, hyperlipidemia, head trauma, meningitis, etc. can cause tinnitus.
