The main manifestation is middle ear injury, often dislocation or fracture of ossicles. When the tympanum is damaged and the eardrum is not broken, there is blood in the tympanum, the eardrum is blue, and blood can be contained in saliva. When the eardrum ruptures, blood flows out of the external channel. If the meninges rupture, there is cerebrospinal fluid otorrhea.

Long-term cerebrospinal fluid otorrhea can cause meningitis, and deafness can occur when the middle ear is injured. A small number of facial nerves are involved, and facial paralysis and loss of taste in the front 2/3 of the tongue may occur. Facial paralysis is mostly temporary.
