Flaccid tympanic membrane is usually associated with rupture of tympanic membrane, congenital developmental abnormality, ear inflammation, etc. Conservative or surgical treatment can be taken according to the condition. 1. Tympanic membrane rupture: Usually related to trauma, when the tympanic membrane is ruptured by violent attack or air pressure injury, the examination will find that the tension part of the tympanic membrane is in a flaccid state. After diagnosis, it is recommended to do tympanoplasty as soon as possible, which can restore the integrity of the tympanic membrane. 2. Congenital developmental anomalies: generally occurring in childhood, if not fully developed after the age of 8, hearing reconstruction should be done as soon as possible, or tympanoplasty. 3. Inflammation of the ear: for example, otitis media, otitis externa, etc., stimulated by inflammation, the tense part of the tympanic membrane will also be in a state of relaxation. If bacterial infection is confirmed, oral cephalosporin should be taken as prescribed by the doctor, and topical levofloxacin ear drops should be used for anti-inflammation. Tension of the tympanic membrane relaxation, if only transient, generally have little effect, but it is recommended to go to the hospital otorhinolaryngology, standardized diagnosis and treatment.
