The time it takes for a patient to heal from a slap to a perforated eardrum varies from person to person and cannot be generalized. Trauma can lead to perforated eardrums, which can be characterized by tinnitus, ear pain, hearing loss, and bleeding from the ear. In the event of an eardrum perforation, patients should actively prevent infection by prohibiting water in the ear and not taking any drops, and taking oral cephalosporins as an anti-inflammatory. If the perforation is small and not complicated by infection, it will usually heal on its own in a month without special treatment and will be reviewed by the ENT department in three months. If the eardrum does not heal, or if the area of the perforation does not shrink, then tympanic membrane repair surgery is required. If the area of the perforation is large, repair surgery should usually be performed directly, and the healing time is relatively longer. In addition, patients should avoid the occurrence of colds, as secondary infections can lead to a gradual increase in the size of the perforation. In addition, patients should pay attention to rest, a light diet, less spicy and stimulating food, and avoid noise stimulation and cold to promote the healing of the eardrum after eardrum perforation.
