External auditory canal cholesteatoma involving the zygomatic arch root is rare. A 15-year-old youth with aural stenosis had a history of right temporomandibular joint trauma and right external auditory canal cholesteatoma surgery. Computed tomography (CT) showed soft tissue density from the attic to the root of the zygomatic arch. The lesion showed high signal intensity in diffusion-weighted magnetic resonance imaging (MRI) and the case was diagnosed as external auditory canal cholesteatoma, subsequently resected combining retro auricular and pre auricular approaches.
