Treatment of chronic suppurative otitis media is simply divided into observation, drug conservative treatment and surgery. The traditional classification and typing of otitis media divides purulent suppurative otitis media into three types: simple, osteochondritic (granulomatous) and cholesteatomatous, but currently cholesteatomatous otitis media (or middle ear cholesteatoma) is divided into separate types. Simple otitis media is usually treated with medication through antibacterial, pus drainage, swelling reduction, medication, and physical therapy, and small perforations can generally heal on their own after the inflammation is completely controlled. If the following problems remain after conservative treatment: large central perforations that have not healed for more than six months, surgery is usually performed after one month of dry ear; when conservative treatment for bone ulcer type is ineffective, surgery should be performed; when conductive deafness or mixed deafness remains and hearing needs to be improved; when cholesteatoma type must be operated in time because destruction of bone often leads to intracranial and extracranial complications, surgery, tympanoplasty + tympanoplasty, may be considered. The purpose of surgery is to remove the lesion and achieve dry ear; to improve hearing, and if necessary, to improve hearing by hearing chain exploration hearing reconstruction; to improve the quality of life to alleviate the recurrent middle ear infections after a cold or water in the ear, and to allow normal bathing or swimming. Middle ear cholesteatoma requires radical mastoid surgery and modified mastoid radical surgery: It is to eradicate the mastoid, the tympanic sinus and the lesion inside the tympanic chamber, and the tympanic membrane is perforated to connect the three to the external ear canal, forming a cavity with a compound epithelium. The purpose of the operation is to completely remove the papillae, tympanic sinus, tympanic chamber and tympanic bullae lesions, stop the flow of pus, obtain a dry ear and prevent intracranial and extracranial complications. It is suitable for osteoid otitis media and cholesteatoma otitis media with various otogenic complications. Tympanoplasty: This is an operation to eradicate middle ear lesions and reconstruct the sound-transmitting structures of the tympanic chamber. The aim is to remove the lesion and repair the tympanic membrane and reconstruct the auditory chain to improve hearing.
