There are the following clinical possibilities for small black dots inside the ear: the first condition is some moles inside the ear canal, which may be caused by congenital factors or acquired local infection, or long-term physical factors or chemical stimulation, which may lead to moles inside the ear canal, and can generally be examined clinically, and if malignant melanoma, basal cell carcinoma, etc. are ruled out, they can be observed and can be left untreated for the time being. In the second case, there are patients who have external ear canal boils, which may be caused by the patient pulling out the ear or local infection, and the patient has pain and other obvious discomfort. In this case, anti-inflammatory treatment is required, and local antibiotic ear drops can be administered for anti-inflammatory treatment. Once the boil forms an abscess, the abscess can be removed and treated with a medication change to promote recovery.
