| Research Abstract |
We investigated the clinical risk factors of Eosinophlic Otitis Media (EOM) and established the diagnostic criteria of EOM. Moreover, we investigated the localization of periostin, an extracellular matrix protein, in middle ear specimens of eosinophlic otitis media (EOM) patients accompanied and of a newly constructed animal model for EOM. Periostin-positive immunostaining was observed in the middle ear sections obtained from the EOM patients with/without asthma. In the animal model, immunoreactivity for periostin was also seen. These results suggested that periostin plays an important role in subepithelial fibrosis in the middle ear of EOM.
