The causes of tinnitus after a fall may be caused by trauma, such as tympanic membrane perforation and ear canal injury, which need to be diagnosed by head CT and otoscopy, etc., and the treatments are different for different causes. 1. Perforated eardrum:The external force of a fall causes a sudden rise in pressure in the external ear canal, leading to perforation of the eardrum, which can cause tinnitus, and may be accompanied by pain, hearing loss, etc. Smaller perforated eardrums can occur over a period of time. Smaller perforations of the eardrum may heal on their own after a period of time; larger perforations may be treated with tympanoplasty. 2. Ear canal damage: The external force of a fall may cause damage to the ear canal, resulting in bleeding and edema, which may lead to reduced conduction function or even damage to the auditory nerve, resulting in tinnitus. At this time, you should consult a doctor in time, and can be under the guidance of the doctor to treat the symptoms. It is recommended to go to the hospital in time to complete the relevant examination, to clarify the cause of symptomatic treatment.
