A review of the radiological anatomy of the round window.
Experimental studies on dried temporal bones in various projections combined with studies of the anatomical details marked with metal wires and/or barium paste have been performed to define the round window and its anatomical relation to surrounding structures. The exact plane of the round window was not found to be tomographically demonstrable and the term to describe the dehiscence in the lateral wall of the promontory below and posterior to that of the oval window should be the niche of the round window. Previous radiologically described pathological changes at the round window should be reviewed.
