Tinnitus is a subjective symptom that patients can hear by themselves, but there is no sound-emitting source present around the outside world. Tinnitus caused by car accidents is treated in different ways for different injury sites, as follows: 1. Blood crust in the external ear canal, adhering to the periosteum, is relatively simple to deal with, and the blood crust can be cleaned up; 2. Trauma injures the middle ear, resulting in perforation of the tympanic membrane or dislocation of the auditory fissure, and the middle ear needs to be explored for reconstruction of the auditory fissure and repair of the tympanic membrane, and tinnitus can disappear after restoring the structure and function of the middle ear. For single-factor causes, surgery is more effective. 3. If not only the outer and middle ears are injured, but also the inner ear is damaged, it should be eliminated as much as possible. For trauma-induced inner ear edema, short-term hormone therapy and enhanced venous return drug horse chestnut seed extract can be used for treatment, and nutritional drugs such as methylcobalamin and vitamin B12 should be given for nerve injury, and inner ear circulation should also be improved, such as treatment with ginkgo biloba preparations; 4. The tinnitus caused by car accidents is usually not just a single part, but often comprehensive, and tinnitus is sometimes closely related to psychological factors, and a serious car accident may cause mental trauma, which also requires psychological guidance treatment.
