RT Journal Article SR Electronic T1 Fenestration Surgery for Otosclerosis: CT Findings of an Old Surgical Procedure JF American Journal of Neuroradiology JO Am. J. Neuroradiol.

We report a case with unique CT findings of a patient who underwent fenestration surgery for otosclerosis in the early 1940s. Recognition of this old surgical procedure on the imaging scans may avoid misdiagnosis of labyrinthine fistulae or middle and inner ear malformations.
