When a congenital cholesteatoma is diagnosed early as a localized circumscribed mass, it can be resected with a very low risk of recurrence.

External auditory canal cholesteatomas, which result from the deposition of squamous epithelium deep to the skin of the external canal, can be caused by postsurgical implantation, radiation, or trauma.

Abstract
A 10-year-old boy presented with a complaint of a left-sided nasal obstruction with an associated foul-smelling discharge. Physical examination and anterior rhinoscopy revealed that a whitish, friable mass had completely filled the left nasal cavity. On computed tomography, a soft-tissue mass was seen filling the cavity and extending to the paranasal sinuses with bone erosion. A biopsy of the mass suggested that it represented a cholesteatoma. The lesion was removed via nasal endoscopy, and histopathology confirmed the diagnosis of a cholesteatoma. No recurrence was noted during 6 months of follow-up. Cholesteatoma of the paranasal sinuses is a rare entity, as only a few dozen cases have been reported in the literature.

Abstract
The external auditory canal (EAC) is an unusual location for a cholesteatoma. We present the cases of 2 patients with EAC cholesteatoma who experienced extensive damage that extended from the inferior EAC wall to the infratemporal area; there was no mastoid involvement. In both cases, the cholesteatomas were removed under local anesthesia and the inferior canal wall was reconstructed with a technique that involved the placement of a pedicled musculoperiosteal flap, a cartilage graft, and a full-thickness skin graft. This simple procedure preserves a normal EAC contour, middle ear space, and mastoid cavity.

Abstract
Spontaneous cholesteatoma of the external auditory canal (EAC) is an uncommon condition that is difficult to diagnose. In a patient with such a possibility, serious clinical investigation along with radiologic and histologic exploration should be performed early on because a delay in treatment can lead to severe complications. Given the rarity of EAC cholesteatoma, no therapeutic consensus has emerged. The type of management depends on the extensiveness of invasion and bone erosion and the status of the neighboring structures. The primary therapeutic objectives are to eradicate the cholesteatoma and then to fill in the residual cavity, which in our opinion can be best accomplished with a muscle flap and EAC reconstruction. Postoperative follow-up should be carried out to look for infections, stenosis, and recurrence. We report a new case of spontaneous EAC cholesteatoma, and we review its diagnostic and therapeutic challenges.
