Histopathology of the Mucosa of Eustachian Tube Orifice at the Middle Ear in Chronic Otitis Media With Effusion: Possible Insight Into Tuboplasty Failure.

CONCLUSION: In ears affected by OME, the mucosa of the Eustachian tubal orifice at the middle ear is most often severely thickened. Normal mucosa, mucosa with severe polypoid changes, or a complete fixed obstruction are possible but uncommon. The majority of specimens studied had sufficiently diseased mucosa to raise questions regarding whether thickened mucosa in the tubal orifice may act as a barrier to middle ear ventilation that would not be directly addressed by cartilaginous Eustachian tube balloon dilation.
