Tinnitus can be caused by ear, nose and throat (ENT) disorders. Tinnitus can be caused by ear diseases, central nervous system diseases, and anxiety disorders, etc. Specific departments include ENT, Neurology, Neurosurgery, and Psychology Clinic. 1. Ear diseases: otitis media, tympanic membrane perforation, abnormalities of the auditory chain and other diseases can cause tinnitus, and can be further investigated in the Department of Otorhinolaryngology. 2. Central nervous system diseases: tinnitus caused by insufficient blood supply to the brain can be further investigated in the Department of Neurology; tumor lesions can also lead to tinnitus due to compression of the auditory nerve, which can be investigated in the Department of Neurosurgery. 3. Anxiety: Emotional tension and anxiety can easily cause tinnitus, which needs to go to the psychological clinic for further diagnosis and treatment. If there is obvious tinnitus, you can go to the ENT department first to find out the cause and then go to the corresponding department for diagnosis and treatment.
