Otitis media requires careful attention to avoid water entering the ear and patients digging into their ears, as well as keeping warm to reduce the chances of catching colds and coughing. Otherwise, otitis media may recur and fail to heal. Otitis media is a common disease in otolaryngology and can be divided into several types, including acute otitis media and chronic suppurative otitis media. For acute otitis media, it usually follows a cold or cough, and patients often exhibit clear symptoms of bacterial infection. Treatment typically involves antibiotics and ear drops, and patients' otitis media can usually be cured. The causative factors for chronic suppurative otitis media mainly include infection of the middle ear cavity and cholesteatoma. Treatment often requires a radical mastoidectomy to achieve cure.
