To undergo ear cleaning treatment, patients need to see an otolaryngologist. Ear cleaning treatment should not be done blindly either, but needs to be done selectively for the needs of the patient’s condition. Patients whose ear canal itself is relatively unobstructed and clean and does not have excessive cerumen masses or abnormal secretions do not need special cleaning of the ear canal. If there are large soft cerumen masses or mucopurulent secretions in the ear canal, the ear canal can be cleaned with cerumen hooks, tweezers, suction devices, etc. If hard cerumen is present, it should be softened with 4% soda drops for about 3 days and then re-cleaned in the hospital. When cleaning, it is important to ensure safety and avoid damaging the skin of the ear canal and the eardrum.
