Ossicular erosion from a posterior pars tensa retraction cholesteatoma

ABSTRACT

@#A 14-year old female with Down syndrome presented with a 3-year history of recurrent purulent left otorrhea. The discharge had become more frequently blood-tinged. Otologic examination revealed a stenotic ear canal with polypoid granulation obstructing the view of the tympanic membrane. High resolution computerized tomographic (HRCT) imaging of the temporal bone was performed to assess the status of the middle ear and mastoid. Particular attention was given to assess for bony erosion associated with cholesteatoma formation.
