The effect of BMP-2, BMP-4 and BMP-6 on bone destruction of cholesteatoma presence

The expressions of BMPs, BMP-2 and BMP-6, were elevated in cholesteatoma tissue. Furthermore, the positivity of BMPs expression was statistically significant in patients with destruction of all the ossicles, and we think that this marker can be used for evaluation of the aggressiveness of cholesteatoma.
