Patient: I have had a piece of earwax in my right ear since I was a child, and it is hard and painful when I touch it. I wanted to go to the hospital, but I was worried about the effect of the treatment on my eardrum, so I didn’t dare to go. When I was younger, I saw it in a small clinic, and it was painful, but I could not hear anything for a few days, so I didn’t dare to see it again. The results of the tests and examinations: Last year’s physical examination at your hospital said it was earwax. A: Cerumen is a minor problem, and some of it does not form ear canal embolism and does not require treatment; some of the patients with cerumen embolism can be removed on the spot in an outpatient clinic. But occasionally cerumen is a tricky problem that requires cooperation with the doctor, several follow-up visits, and application of ear drops to soften the cerumen. Because of cerumen embolism, softening and removal fails, requiring inpatient microscopic surgery, which is, after all, an isolated case.
