Changes of intratympanic pressure in secretory otitis media.
A thick, gluey effusion was observed to out of the middle ear after myringotomy only in some cases of secretory otitis media. Cytologic analysis of intratympanic transudate in 321 cases of secretory otitis media in children showed the cellular infiltration to result in increased viscosity of the middle ear content. It caused gradual change in the middle ear pressure, from the initially negative to positive pressure in the advanced stages of the disease.
