High-resolution temporal bone CT without contrast (Table 1, Group 1 Patient 2). (A) Traditional axial CT images are shown. (B) Inverted axial CT images. (C) Cochlea (blue) and facial nerve (yellow) have been colorized and superimposed over inverted images in the axial plane for both the left and right ears. Note that a cochlea-facial nerve dehiscence (CFD) is seen on the right and a cochlea-facial partition between the cochlea and the facial nerve is seen on the left. The patient had left-sided third window syndrome (TWS) symptoms due to a CT negative TWS, with resolution of his TWS symptoms after round window reinforcement on the right and left.
