Bloated external ear canal

External ear canal bloat is an acute localized purulent lesion of the external ear canal skin, also known as local external ear canal inflammation. Occurs in the cartilage of the external ear canal, which is one of the common diseases of the ear. Frequent in summer. The cause is mostly ear-cutting damage to the skin of the external auditory canal or water accumulation in the external auditory canal during bathing and swimming, which softens the local epidermis and is easily infected by bacteria. In addition, the impregnation of purulent otitis media with pus, and certain systemic diseases such as diabetes can also induce edema of the external ear canal.
