Results

One-hundred consecutive ED patients without vertigo, 100 ED patients with explained vertigo, and 100 ED patients with unexplained vertigo were enrolled. The SSC of each patient was examined and interpreted by fellowship trained neuroradiologists (Fig. 1).

Fig 1: Manual pöschl reformation creation and interpretation. Pöschl reformations were created from bone kernel, thin slice (0.5 or 0.63 mm) axial images of the temporal bone from high-resolution non-contrast CT head (NECTH) to evaluate the superior semicircular canal (SCC). A pöschl view of the SCC was created by creating a reformation of the canal in a sagittal, oblique plane that was perpendicular to the petrous ridge (Image A). The plane of reformation is demarcated by the red line in image A. Image B demonstrates a screenshot of the reformation that demonstrates a superior semicircular canal dehiscence. Image C demonstrates a screenshot of a coronal reformation that also demonstrates SSD (red arrow).
There was a statistically significant difference in prevalence of SSC abnormalities in ED patients without vertigo (5%, 95% CI [1.3%-10.7%]) compared to ED patients with explained vertigo (16%, 95% CI [8.8%-23.2%]) (P = 0.02) and ED patients with unexplained vertigo (25%, 95 CI [16.5%-33.5%]) (P = 0.0001). There was not a statistically significant difference in prevalence rates between ED patients with explained vertigo and ED patients with unexplained explained vertigo (P = 0.16). These results are summarized in Table 1.
