Two cases of cholesteatoma behind intact tympanic membrane with embryogenetic anomalies.
Two new interesting cases of cholesteatoma of the middle ear behind an intact tympanic membrane are presented in this report. In both cases, which would fulfill Derlacki's criteria for a congenital cholesteatoma, the presence of an embryogenetic anomaly in the affected ear was noted. This association is suggestive of the congenital hypothesis of the observed cases.
