The most common thing that is pulled out of the ear is cerumen, also known as earwax and earworms. Cerumen is secreted by the cerumen glands in the skin of the outer ear canal. There are more and less cerumen, and crumbly or small pieces are more common. Most of it can come out from the ear on its own, and some of it can be pulled out with an ear spoon, but if it is not cleaned for a long time, it will accumulate more and more. The cerumen secreted by the cerumen gland is sticky and more abundant, forming large and hard masses that seriously cause hearing impairment. After getting into the water while swimming or bathing, the cerumen is swollen by the water blisters, causing ear stuffiness and inability to hear, and if combined with infection, there will be obvious ear pain. It may also be a cholesteatoma of the external ear canal, where a large amount of cholesteatoma epithelium is generated and blocks the external ear canal, combined with a small amount of cerumen. Cholesteatoma of the external ear canal requires surgical treatment.
