Pathophysiology of Chronic Otitis Media
Generally, otitis media from the nasopharynx and the middle ear, except in relatively rare cases, which have a bacterial infection that leaked the tympanic membrane.
Early stages of this complication begins with hyperemia and edema on the mucosa of the pharynx eusthacius tuba, which is then narrowed by hyperplasia of lymphoid lumennya the submucosa.
Disruption of the middle ear ventilation is accompanied by accumulation of fluid exudate and transudate in the middle ear, middle ear as a result become very susceptible to bacterial infections that come directly from the nasopharynx. Further factors of host resistance and bacterial virulence body will determine the progression of the disease.
