RESUMO
Bilateral congenital cholesteatomas are rare. We present the 8th and 9th case of this entity in the literature. One of these cases is especially unusual. In that patient an ear that had been documented as normal, both radiographically and clinically, was found to have a large cholesteatoma 18 months after the contralateral ear had been treated for the same disease. The theories of the pathogenesis of this entity are also reviewed. Our cases support several of these theories. In fact, in one of the patients, it is possible that a different etiology was involved in each ear. Incidental note is made of the fact that three of the nine reported cases of bilateral congenital cholesteatoma have occurred in the same geographic locale.

Bilateral congenital cholesteatoma in children is unusual, and our experience with a case arising in a 6-year-old boy is described. Various theories of the origin of this disease are briefly reviewed. The possibility that this entity may be more common than previously realized, and its relationship to eustachian tube obstruction and middle ear effusions, are also discussed.
