Congenital cholesteatomata with other anomalies.
Congenital (primary) cholesteatomata may arise in the petrous apex, mastoid, middle ear, or external auditory canal. Histological studies of the temporal bones of a 20-year old man with bilateral combined deafness show bilateral congenital cholesteatomata of the middle ears associated with dalivary choristomata and other anomalies of the middle and inner ears.
