Tomographic Examination of Cholesteatomas in the Middle Ear

A retrospective investigation of the diagnostic certainty in radiological examinations of cholesteatomas in the middle ear has been made. Through a period of six years the security has proved to be more than 90%. Small cholesteatomas which have not yet caused osseous destruction and cholesteatomas in earlier operated ears are barely accessible to radiologic evaluation. The oto-radiological experience of the describing radiologist must be emphasized.
