[Adhesive otitis media with cholesteatoma]
Objective:
To explore the mechanism of cholesteatoma formation in adhesive otitis media with cholesteartoma.
Method:
Three cases of this kind of disease were reported and literatures were also reviewed.
Result And Conclusion:
1. It is a acquired primary cholesteatoma. 2. The eustachian tube and tympanic isthmus block are the direct cause of these cholesteatoma. 3. CT examination of the temporal bone is more valuable in diagnosis than that of normal X-ray. 4. If the cholesteatoma lesions can be removed completly, tympanoplasty may be performed in first stage or separate stage.
