Otitis media can be broadly divided into four categories: 1. secretory otitis media. 2. 2.Purulent otitis media. 3. Cholesteatoma of the middle ear. 4. Special types of otitis media, (tuberculosis, syphilis, AIDS, fungal, necrotizing, radioactive, pneumatic otitis media, etc.). In fact, due to the complex anatomical relationship between the middle ear mastoid, the large blood vessels, the facial nerve across the tympanic cavity, the terminal cells of the auditory nerve, and the semicircular canal that keeps the body in balance, sometimes the conservative treatment of acute and chronic middle ear mastoid controls the symptoms but still leaves the hearing impairment, and even after surgery, the hearing Even after surgery, it is difficult to restore the hearing to the level before the onset of the disease, causing lifelong regrets, and in more serious cases, it can lead to intracranial and extracranial complications, causing damage to the corresponding anatomical structures and functions, and even endangering life. The common extracranial complications of otogenic complications are: subperiosteal abscess behind the ear, labyrinthitis, and apoplexy, leading to otogenic facial palsy, vertigo, hearing loss, and even total deafness. Intracranial complications: meningitis, brain abscess, brain hernia, etc. cause high fever, headache, confusion and coma. With the improvement of people’s health awareness and the application of antibiotics, the incidence of intracranial and extracranial complications of otitis media has been decreasing year by year, but this potential hazard of otitis media still exists, and otitis media is also one of the common causes of deafness. In summary, when you have otitis media, you must pay enough attention to it, and it is recommended that those who suffer from otitis media should receive early treatment, regular review and specialist consultation to prevent complications. Protecting our hearing and caring for our lives is a matter of urgency.
