Etiology of adhesive otitis media

Adhesive otitis

media refers to the formation of fibrosis and adhesion between the acoustic structures of the middle ear and the tympanic wall, resulting in conductive deafness. Under normal circumstances, it is mainly the sequela of poor healing of various acute and chronic otitis media. The mechanism is that inflammation stimulation causes damage to middle ear mucosa. At the same time, if the patient does not receive timely treatment, it may lead to new fibrous tissue produced by fibroblasts in granulation tissue or effusion organization, and then adhesion between tympanic membrane inner wall mucosa and tympanic membrane, resulting in movement disorder of middle ear acoustic structure system and conductive deafness.
