Tinnitus and tinnitus are two different diseases, and the impact of these two diseases on patients is also different. 1. Tinnitus: Tinnitus can be caused by intracranial lesions, such as: intracerebral space-occupying lesions, intracranial vascular malformations, cerebrovascular disease, etc.; it can also be caused by mental stress, such as: overexertion, high-pressure state, mental overstress, etc.. 2. Tinnitus: Tinnitus can usually be clearly felt as an abnormal ringing sound in the ears. Tinnitus is mostly caused by ear diseases, such as otitis media, arterial pulsation near the ear, blockage of the ear canal, abuse of ototoxic drugs, etc. A few of them may also be related to neurological diseases. Whether it is tinnitus of the brain or tinnitus of the ear, patients may experience improvement of their symptoms after active treatment, and in some cases, the symptoms may persist for a long time, but they will not affect their life expectancy as a result. It is recommended that patients with these symptoms seek medical attention in a timely manner and standardize their treatment.
