There is tympanic membrane invagination, so we should treat it symptomatically. If you have secretory otitis media, throat diseases or rhinitis, you should cure these diseases first. Secondly, the eustachian tube blowing method is used to dredge the eustachian tube. The specific method is: hold your nostrils and hold your breath to inflate outward, but the force must be appropriate and must be carried out under the guidance of an experienced doctor. If the force is too strong, it is easy to cause the eardrum to rupture. When using this method, we should pay attention to the possibility of nasopharyngeal infection spreading to the middle ear, especially when there are many inflammatory secretions in the nasopharynx. Don't pinch your nose or inflate it. In the acute stage of eustachian tube inflammation, obstruction and nasal congestion caused by cold, do not do patency check and blow your nose, and do not blow your nose too hard. At this time, some mucosal astringents such as ephedrine should be ordered in time to keep the nasal cavity unobstructed and prevent otitis media. I wish you health and happiness.
