If your ears are oily, mostly due to greasy ears, and there is no other discomfort, you can use a clean dry cotton swab to clean the ear canal. If oily ears are combined with itching, pain, ear blockage, tinnitus and other discomforts, it is recommended to go to the hospital as soon as possible for further treatment under the guidance of a doctor. In some people, earwax (earwax) is sticky and greasy, commonly known as “greasy ears”, and is genetically linked. For asymptomatic oily ears, you can gently wipe them with a dry cotton swab, keep the external ear canals clean and dry, and avoid repeated forceful digging with sharp objects. If the ear is watery and repeatedly digging hard, it is easy to cause bleeding in the external ear canal, otitis media, otitis externa and other diseases. If oily ear is more serious, or combined with itching, pain, ear blockage, tinnitus and other discomforts, you should go to the ENT department of the hospital as soon as possible, to clarify the cause of the disease and carry out the treatment. For example, if cerumen embolism, you can use sodium bicarbonate solution to rinse out the ear canal or endoscopy to clean up the cerumen; in case of otitis externa or otitis media, you need to have a hydrogen peroxide ear bath or order of ofloxacin drops to treat the disease, and the treatment of of ofloxacin is prohibited in the patients who are allergic to ofloxacin. Although oily ears will lead to increased oily secretions in the ear canal, patients should not frequently wipe the ear canal with cotton swabs, which may damage the ear canal and cause pain and bleeding, and in severe cases, may even lead to secondary infection. It is recommended that patients with oily ears should not frequently wipe their ear canals with cotton swabs, reduce the number of times they wear headphones, and avoid moist ear canals in their daily lives. Once there are uncomfortable symptoms, as soon as possible to the hospital ENT department for further examination and treatment.
