  • Title: [Cholesteatoma formation in an ear fistula--model of the development of genuine cholesteatoma?].
    Author: Stammberger H.
    Journal: Laryngol Rhinol Otol (Stuttg); 1983 Oct; 62(10):471-3. PubMed ID: 6645748.
    Abstract:
    A 20-year-old patient had developed a cholesteatoma in the depth of an ear fistula. Fistula and cholesteatoma had formed a canal in the mastoid bone running parallel to the outer ear canal and behind it, being of almost the same size. This canal ended in a "blind alley" merely fractions of a millimeter lateral of the attic without establishing contact to the middle ear. Histologically, ceruminal glands could be demonstrated in the tissue layer of the fistula. A possible interpretation is that this fistula represents remnants of a duplication of the outer ear canal. The development of "genuine" cholesteatomas out of cases similar to this one is discussed--when the cholesteatoma reaches the middle ear behind an intact drum.
