Chronic suppurative otitis media is a chronic purulent inflammation of the middle ear mucosa, periosteum or deep into the bone. Chronic otitis media is a common disease whose main symptoms are hearing loss and pus flowing from the external ear canal, accompanied by tinnitus, vertigo, and even facial paralysis, and can cause serious intracranial and extracranial complications. In the general mind, chronic suppurative otitis media can only cause hearing loss and pus flowing from the external ear canal, so people think that it can be controlled by using only anti-inflammatory drugs and local application of ear drops. The middle ear includes the tympanic chamber, sinus, eustachian tube and mastoid, and is adjacent to the facial nerve, inner ear and posterior cranial fossa. As a result, inflammation of the middle ear can cause damage to these structures, resulting in tinnitus, facial paralysis, and even serious intracranial and extracranial complications. Since the middle ear is not only an organ of hearing but also an organ of balance, inflammation of the middle ear can cause not only hearing loss but also symptoms of balance disorders such as dizziness with rotating vision. Otitis media can be extremely dangerous to our health, and to avoid these risks and maintain a healthy ear, we must understand how to get the best treatment. Chronic suppurative otitis media is divided into simple, osteochondritic and cholesteatomatous types. Surgical treatment is the best option. Early diagnosis and surgery is the best way to get better hearing and keep the middle ear free from the disease and avoid further damage. What tests should be done before surgery for chronic suppurative otitis media 1. Local specialist examination. 2.Hearing examination. 3. Eustachian tube function examination. 4.CT examination of temporal bone, etc. Sequelae and complications of chronic suppurative otitis media 1. Adhesive otitis media. 2.Sclerosis of the tympanic chamber are all treated mainly by surgery. Complications of chronic suppurative otitis media include extracranial complications, namely, subperiosteal abscess behind the ear, labyrinthitis, and Bezold’s abscess in the neck, and intracranial complications include dural abscess, sigmoid sinus thrombophlebitis, suppurative meningitis, and brain abscess. The surgical treatment of chronic suppurative otitis media mainly includes tympanoplasty, tympanoplasty plus open mastoid radical surgery, tympanoplasty plus complete mastoid radical surgery, and otolaryngology of our hospital adopts the treatment and surgical methods of the House Ear Institute of the United States with international advanced standards, which can expose the lesion in all directions and from multiple angles, thus removing the lesion while maximizing The Department of Otolaryngology adopts the international advanced House Ear Institute’s treatment and surgical methods to expose the lesions in all directions and from multiple angles, so as to remove the lesions while preserving the functions and anatomical structures to the maximum extent and achieve satisfactory treatment results. The main surgical methods used are: fascial implant tympanoplasty, fascial implant tympanoplasty with open or complete mastoid radical treatment, etc.
