Eardrum perforation in children generally has two causes: one is caused by acute trauma, such as ear pulling or slapping, and the perforation is usually in the flaccid part of the eardrum. On examination, a bloody discharge is seen in the external ear canal and a circular perforation is visible in the loose part of the tympanic membrane with fresh blood oozing out. The patient will experience symptoms associated with ear pain, hearing loss, and tinnitus. In terms of treatment, this traumatic tympanic membrane perforation requires oral anti-inflammatory medication to avoid local infection, as well as avoiding water in the external ear canal and not blowing the nose forcefully, which can heal itself in about a month. Another type of tympanic membrane perforation is caused by acute otitis media. Due to acute upper respiratory tract infection, when the inflammation is heavy, it causes fluid to accumulate in the eustachian tube, leading to perforation of the eardrum. This tympanic membrane perforation is usually in the tense part of the tympanic membrane, and the patient will experience symptoms related to pus flow from the external ear canal, ear pain, and hearing loss. In terms of treatment, this type of tympanic membrane perforation requires symptomatic anti-inflammatory treatment, which can be treated with fluids, which is more effective. At the same time, the patient needs to use nebulized inhalation to reduce edema as well as congestion in the eustachian tube, so that the pus can drain faster, and the treatment course is about one week.
