Osteoma of the
temporal bone most commonly occurs in the
external ear.
Osteomas in the
middle ear are not common, and only 25 relevant cases (18
papers) have been reported in the English
literature. With only 5 cases reported to date,
osteoma of the promontory in the
middle ear is rare. This study
reports a case of asymptomatic
osteoma of the promontory in the
middle ear mimicking a
congenital cholesteatoma in a 4-year-old
girl.
