title: Two cases of cholesteatoma behind intact tympanic membrane with embryogenetic anomalies.
abstract: 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.
