Expression of periostin in the epithelium of cholesteatoma with different degrees of ossicular chain destruction and its clinical value in predicting postoperative hearing recovery

The expressions of periostin, Interleukin 6, and tumor necrosis factor-alpha were markedly increased in the epithelium of middle ear cholesteatoma patients, which were gradually increased with the aggravation of the ossicular chain destruction. Periostin, Interleukin 6, and tumor necrosis factor-alpha could be used as important indicators to predict postoperative hearing recovery.
