The buzzing in the ears caused by external force is considered to be caused by traumatic perforation of the eardrum, damage to the inner ear or damage to the auditory center. 1. Traumatic tympanic membrane perforation: When an external force acts on the outer ear, the shock wave generated can directly affect the tympanic membrane, resulting in tympanic membrane rupture and perforation. At this time, patients can often feel sudden ear pain, hearing loss, tinnitus, ear tightness and bleeding from the external auditory canal and other manifestations, so it can be seen that the external force caused by the buzzing of the ears. 2. Inner ear injury: when the head is subjected to severe external force, it can cause skull fracture, especially the transverse fracture of the fracture line through the temporal bone, which may damage the semicircular canal and cochlea. Damage to the cochlea can have tinnitus and hearing loss and other manifestations; while damage to the semicircular canals have vertigo and imbalance and other manifestations, so it can be seen that the external force leads to the buzzing of the ears. 3. Damage to the auditory center: If the central nervous system is damaged due to a great external force, the function of the auditory center may also be affected, which often causes tinnitus, hearing loss and other manifestations, so it can be seen that external forces lead to buzzing in the ears. Once the buzzing in the ears caused by external forces, often suggests that the condition is more serious, it is recommended to consult a hospital as soon as possible, active diagnosis and treatment.
