Otitis media primarily refers to the acute and chronic inflammation of our middle ear tympanic membrane, tympanic cavity, and mastoid cavity. Clinically, when ear drops are needed for treatment, it mainly refers to acute otitis media, which is primarily caused by bacterial infection, such as Staphylococcus aureus, Streptococcus pneumoniae, etc., caused by bacterial infection. Therefore, the ear drops mainly used are antibiotic eye drops, such as ofloxacin eye drops, lomefloxacin eye drops, compound polymyxin B ear drops, penicillin, hydrocortisone eye drops, etc. It is important to note that some special ear drops, such as phenol ear drops, can be used when the patient is not in pain. However, if the patient has a tympanic membrane perforation, then phenol ear drops should not be used, as they have the effect of burning the mucous membrane of the middle ear, so they cannot be used. (Note: The above medications should be used under the guidance of a doctor.)
