Middle ear lipoma mimicking a congenital cholesteatoma: A case report and review of the literature.

OBJECTIVE

To describe a case of middle ear lipoma, review the current literature, and discuss the surgical approach.

METHODS

Published case reports in the English literature of lipomas restricted to the middle ear were reviewed. The presentation, location, and management of the middle ear lipomas were analyzed.

RESULTS

Histological examination of the resected middle ear lesion was compatible with lipoma. Review of the literature suggests middle ear lipomas are rare and involve the epitympanum.

CONCLUSION

Lipomas should be included in the differential diagnosis for middle ear lesions. Adequate surgical exposure can be achieved through a transcanal approach, with particular attention to carefully elevate the tympanic membrane off the malleus, preserving the integrity of the ossicular chain.
