Abstract:
The classic presentation of congenital cholesteatoma is a pearl behind the anterior-superior quadrant of an intact tympanic membrane. Idiopathic hemotympanum is characterized by a dark blue eardrum, the most prominent feature of which is the presence of cholesterol granulomas. Blue eardrum is associated with eustachian tube dysfunction. Despite the well-established relationship between eustachian tube dysfunction and the development of pediatric cholesteatoma, little has been written concerning the appropriate timing of tympanostomy tube placement. To date, there are no reports of congenital cholesteatoma associated with blue eardrum. A recent case of advanced congenital cholesteatoma (stage IV) associated with blue eardrum was treated using preoperative tympanostomy tube insertion. Tympanostomy tubes were helpful in preventing recurrence of the cholesteatoma after surgery. The case is presented along with a review of the literature.
