After the ear holes are closed, there are hard lumps in the ear canals, which are mainly seen in two cases: 1. The ear canals are blocked with hard cerumen, which is very common in children because the ear canals of children are relatively thin, and it is not easy to pull out the cerumen, and the cerumen is easily hardened and blocked in the ear canals because the cerumen is stored for a long time inside the external ear canals. In this case, it is recommended that the patient go to an ENT clinic, where the doctor can prescribe ear drops to soften the cerumen, and after 3-4 days of softening, go to the hospital where the doctor can rinse out the cerumen with saline. This approach is the least irritation, most patients can tolerate and the best results, no side damage. 2, some patients have osteoma in the ear canal, with the gradual growth of osteoma, osteoma may block most of the ear canal. In this case, it is generally recommended to consider surgical treatment, and there is no better way to treat it.
