Chronic suppurative otitis media is a common and frequent disease in otolaryngology. Patients suffer from long-term pus in the ear canal and hearing loss, and some patients even suffer from serious intracranial and extracranial complications, which seriously affect people’s daily life. Then how to treat this disease? Wang Zhanyong, Department of Otolaryngology and Head and Neck Surgery, The Fourth Hospital of Hebei Medical University First of all, medication is the principle of local medication and systemic medication under the condition of keeping the drainage unobstructed. It should be emphasized that local medication is prohibited or cautiously used as powder or cream because it violates the principle of unobstructed drainage and is a common mistake made by some medical personnel at the grassroots level. For patients who cannot be cured by medication for more than six months, we recommend surgical treatment to reduce pain and avoid complications. Otomicrosurgery was born in the 1940s and 1950s as a subdiscipline of otolaryngology-head and neck surgery, marked by the use of the operating microscope and the otologic electric drill. The use of this technology has greatly improved the cure rate of chronic suppurative otitis media and reduced the risk of complications such as surgical damage to the facial nerve, thus better benefiting the people.
