Whether or not an indented eardrum will heal on its own needs to be determined by the cause of the indentation. If it is caused by a change in air pressure, it usually heals on its own. If it is caused by pathological reasons, such as cerumen impaction, secretory otitis media, etc., it usually does not heal on its own. 1. Environmental air pressure changes: such as air travel, diving, etc. caused by the internal and external pressure changes in the eardrum can cause disease. If there is no localized inflammation and persistent tympanic membrane invagination, the condition usually resolves itself after the air pressure environment is stabilized. 2. Cerumen impaction: Cerumen impaction can compress the tympanic membrane, thus causing tympanic membrane invagination. This is not self-healing, and the symptoms of tympanic membrane impaction can only be relieved when the foreign body or cerumen is removed. 3. Secretory otitis media: bacterial infection, Eustachian tube dysfunction occurs when there is negative pressure in the middle ear, resulting in congestion and edema of the mucous membrane of the tympanic chamber, which causes an imbalance of atmospheric pressure inside and outside the tympanic membrane, resulting in tympanic membrane depression. If left untreated, it may aggravate the tympanic membrane invagination, which requires active treatment and is usually not self-healing. Ear tympanic membrane invagination may also be caused by other reasons, you should actively go to the hospital to do the relevant examination, after a clear diagnosis, under the guidance of the doctor for targeted treatment.
