Patient: Description of condition (onset, main symptoms, hospital visited, etc.): Dad is 58 years old, his ears were a little backed up before, no examination. 10 days ago, he went swimming, got into the water, and two days later, the eardrum was perforated by endoscopy and chronic otitis media. The doctor prescribed lomefloxacin hydrochloride ear drops, which have been on for more than a week with no effect, and they stung inside the ear when they were on, and now the ear feels stuffy all day. I don’t know what to do. Should I continue to take the medicine? Or should I change the medication? Should I have a tympanic membrane repair after the inflammation has subsided? Wang Zhiqiang, Department of Otolaryngology, The First Hospital of Dalian Medical University: If the diagnosis of chronic otitis media is confirmed and there are no other complications, local treatment is sufficient: first, dab the ear with hydrogen peroxide and wipe it clean (repeatedly dab the ear with hydrogen peroxide and wipe it dry until there is no foam in the ear with hydrogen peroxide), then put in lomefloxacin ear drops (or oxyfloxacin ear drops) in an ear bath for 10 minutes, and do this procedure three times a day, and it should soon be Dry ear. You can do tympanic membrane repair after 1 – 3 months of dry ears (see the clinic again at that time to see if the surgery is done).
