The causes of tinnitus and dizziness are commonly found in sudden deafness, Meniere’s disease and acoustic neuroma. 1. Sudden deafness: the cause of the disease is unknown, and may be related to circulatory disorders, viral infections and other pathogenic factors. Patients often have unilateral deafness, tinnitus, dizziness, nausea, vomiting and ear stuffiness. Among them, tinnitus can be seen before deafness, and dizziness often occurs with deafness, so it can be seen that some patients may have tinnitus, dizziness and other manifestations. 2. Ménière’s disease: this disease is mostly caused by membrane labyrinthine fluid. Patients may have sudden onset of dizziness, hearing loss, tinnitus and ear stuffiness and other typical manifestations, so it can be seen that some patients have tinnitus, dizziness and other manifestations. 3. Auditory neuroma: when the tumor originates from the inner ear canal of the Ⅷ cerebral nerve, the small size of the tumor in the early stage may cause unilateral tinnitus, hearing loss and dizziness, and deafness may occur in a long time. With the increase in size, facial sensory loss, hemiplegia and dysphagia gradually appear, so some patients may have tinnitus, dizziness and other manifestations. When tinnitus, dizziness, alert to the possibility of the above diseases, it is recommended to consult the hospital as soon as possible, identify the cause of the disease, and be actively treated.
