Buzzing inability to hear after being hit in the ear is a common clinical manifestation of ear trauma. Mostly due to the following reasons: First, traumatic perforation of the tympanic membrane, that is, after trauma, due to the sudden increase in the air pressure of the sound waves in the ear canal, especially palm strike injuries, can lead to perforation of the tympanic membrane, manifesting itself as an irregular wedge-shaped perforation of the tympanic membrane tension part, with bruising at the edge. Second, the tympanic membrane soft tissue contusion, although the tympanic membrane does not have obvious perforation performance, but the surface epithelium of the tympanic membrane obvious bruising, congestion. Third, damage to the auditory-sensory sound system of the inner ear, light can be restored, serious permanent hearing loss.
