The early manifestations of explosive deafness are severe earache, persistent tinnitus, hearing loss, and sometimes symptoms such as dizziness, nausea, and vomiting. In severe cases, transient coma, concussion, and total deafness may occur in both ears.Otology examination shows congestion, bleeding or perforation of the tympanic membrane, blood crusts on the surface, and sometimes dislocation of the ossicles.Audiological examinations show that the hearing curve is mostly horizontal or high-frequency steep drop, which may be accompanied by balance dysfunction, spontaneous nystagmus and so on.Therefore, once the ear suffers a blast injury, remember to go to the otolaryngology department or hearing specialist for diagnosis and treatment in time.Generally speaking, the earlier the treatment, the greater the chance of hearing rehabilitation.In mild cases, hearing can be restored or partially recovered after treatment; in severe cases, lifelong deafness and tinnitus can be caused, which is very annoying and painful.
