Abstract
|
|
|
Fibrous dysplasia of temporal bone is a rare disease that may lead to progressive stenosis of external auditory canal. This stenosis leads to trapping of skin and development of cholesteatoma. Most cases with fibrous dysplasia of temporal bone
are
monostotic, and the polyostotic type is far more rare. We have experienced a recurred polyostotic fibrous dysplasia with cholesteatoma on the external auditory canal and the mastoid. Our purpose of this paper is to discuss properties and
management
of
this rare disease. A twenty-one-year-old woman who had undergone canaloplasty for polyostotic fibrous dysplasia of right temporal bone and occipital bone 5 years age returned complaining of intermittent right-sided otorrhea for one year. She
underwent
canal down mastoidectomy with tympanoplasty type 3 for recurred canal obstruction and developing cholesteatoma. The patient has been followed up regularly for one year. There is no evidence of the recurrence of the disease or associated symptoms.
We
emphasize the need for a long term follow-up of patients with this disease as cholesteatoma or restenosis may develop insidiously.
