Tympanic membrane invagination can be secondary to primary diseases such as secretory otitis media, rhinitis, nasal polyps, pharyngitis or pneumatic pressure injury, and common symptoms include: ear stuffiness, tinnitus, hearing loss and self-hearing enhancement. Tympanic membrane invagination is mostly caused by the abnormal function of the Eustachian tube and the negative pressure state of the middle ear, which causes the tympanic membrane to retract and invaginate. Patients will suffer from edema of the mucous membrane of the tympanic chamber, restricted movement of the tympanic membrane, and decreased sound conduction, resulting in ear stuffiness, tinnitus, hearing loss, and increased self-hearing. Due to individual differences between patients, the symptoms of ear discomfort may vary when the tympanic membrane is inverted. It is recommended that patients actively go to a regular hospital for consultation, and should analyze the cause of tympanic membrane entrapment based on past medical history, other accompanying clinical symptoms, and relevant examination results, and then follow the doctor’s instructions for treatment.
