Neurological tinnitus can be roughly divided into three categories according to different lesion sites, such as sensorineural tinnitus, peripheral neurological tinnitus, central neurological tinnitus, etc., the specific causes of tinnitus are as follows: 1. Sensorineural tinnitus: also known as cochlear tinnitus, mainly caused by abnormalities in the structure and function of the cochlea, and some patients are also accompanied by symptoms of hearing loss. There are various causes of abnormal cochlear structure and function, such as the use of ototoxic drugs, noise, senile deafness, cochlear membrane labyrinthine fluid, cochlear vascular lesions, otosclerosis and so on. 2. Peripheral neurogenic tinnitus: It is mainly caused by degeneration of auditory nerve fibers due to auditory neuropathy, which in turn leads to abnormal function. Auditory nerve lesions are commonly caused by tumors such as acoustic neuroma. 3. Central nervous tinnitus: mainly due to tumors, blood supply abnormalities, infections and other causes of central auditory pathway lesions or abnormal function, thus causing tinnitus symptoms. In addition, there may be other reasons that can cause tinnitus, it is recommended that patients go to the hospital in time, under the guidance of professional doctors to carry out the corresponding examination, in order to correspond to the treatment.
