Otic cholesteatoma in the sand rat (Psammomys obesus).
To improve treatment of otic cholesteatoma, a model is needed for conduction of experiments. In the search for such a model, we have found cholesteatoma to occur naturally in Psammomys obesus. We present these findings and suggest the fat sand rat as a model for investigating cholesteatoma.
