Recovery (healing) phase of acute secretory otitis media,showing the presence of bubbles. Minor tympanosclerosis,the presence of white,chalky plaques on the eardrum,the tympanic membrane,is also apparent. Otitis media occurs as a sequel to bacterial or viral infections in the upper respiratory tract,which spreads up via the eustachian tube. Fluid & pus accumulate due to a blocked,inflamed tube; the pressure increase may perforate the eardrum & damage the tiny bones within. The resulting degree of deafness ranges from slight transient to total | |
