Cholesteatoma?
Answers: Cholesteatoma can be a birth malfunction (congenital), but it more commonly occurs as a complication of chronic ear infection.
Sometimes the chronic ear infections are cause by a poorly functioning Eustachian tube. I'm not sure about the genetic point, but I think things similar to small Eustachian tubes can be inherited. Thus cause more ear infections.
