Osteomas in the
middle ear are very rare. To date, there are 23 cases of
osteomas of the
middle ear reported in the English
literature. Of these, five
osteomas arose from the ossicles, but those accompanied by
cholesteatoma is extremly rare. There are only two cases that are all
congenital cholesteatoma. Ossicular
osteoma with primary acquired
cholesteatoma has not been reported previously. We present a case of
osteoma of the
incus accompanied by primary acquired
cholesteatoma, which was diagnosed incidentally in the
middle ear.
