The clinical findings in 37 children with congenital cholesteatoma of the middle ear were detailed in their presentation. The authors hypothesized that congenital cholesteatoma originates from an epidermoid formation that has been identified histologically in the anterior/superior lateral tympanic cavity adjacent to the anterior anulus during fetal development, which, if it fails to involute by 33 weeks' gestation, results in a congenital cholesteatoma and continues to grow.
