A computed tomographic scan of the region was performed (Figure).Denouement and Discussion

    Computed tomographic scan demonstrating narrowing of the left external auditory canal caused by an expansile bone lesion of the temporal bone (curved arrow). The regional bone was characterized by a "ground-glass" appearance. A small cholesteatoma is located between the tympanic membrane and the bony lesion (black arrow).The patient underwent surgical exploration of the ear. The nearly obliterated lumen was widened, and the canal was cleaned
