Whether purulent otitis media is serious or not is related to the specific condition and whether it is effectively treated. Suppurative otitis media can be cured by timely and standardized treatment; if the treatment is not timely or thorough, it can be prolonged to chronic, and may also lead to tympanic membrane perforation, suppurative meningitis, peripheral facial paralysis and other complications, with serious consequences. 1. Perforation of tympanic membrane: If patients have purulent otitis media, if not treated in time, it may lead to perforation of tympanic membrane due to bacterial infection of the tympanic membrane, causing hearing impairment. 2. Suppurative meningitis: If patients with suppurative otitis media are not treated in time, the bacteria inside the middle ear may enter the brain tissue along with the venous valve, causing suppurative meningitis, which is fatal. 3. Peripheral facial paralysis: If not treated in time, purulent otitis media may lead to bacterial attack on the peripheral facial nerve, causing peripheral facial paralysis. It may be manifested by symptoms such as distorted eyes and mouth and inability to close the eyes. It is recommended that once a patient finds out that he or she has suppurative otitis media, he or she should consult a doctor in a timely manner and receive standardized treatment after completing the relevant examinations.
