Tinnitus and deafness may be caused by cerumen impaction, ear inflammation, trauma, neurogenic tinnitus, high blood pressure and so on. 1. Cerumen impaction: some people’s ears secrete more cerumen, which clumps together and presses on the ears, causing tinnitus and deafness. 2. Inflammation of the ear: such as acute otitis externa, boils of the external auditory canal, purulent otitis media, etc. The inflammation stimulates the local tissues to become swollen and painful, resulting in tinnitus, deafness and ear pain. 3. Trauma: the impact of external force leads to fracture of the temporal bone and damage to the nerve or blasting sound leads to perforation of the eardrum, which can induce tinnitus and deafness. 4. Neurogenic tinnitus: poor circulation in the inner ear can lead to neurogenic tinnitus and deafness. 5. High blood pressure: blood pressure fluctuates greatly, and tinnitus and deafness can occur if the blood pressure is not well controlled. Tinnitus and deafness involves more reasons, it is recommended to consult a doctor in time to identify the cause of the disease and follow the doctor’s instructions for treatment.
