Abstract

Objective

To determine the accuracy of 1.5 Tesla magnetic resonance imaging in identifying the bony defect in superior semi-circular canal dehiscence syndrome.

Methods

A retrospective case–control study was conducted in tertiary university settings. The study included 12 patients with a definite diagnosis of superior semi-circular canal dehiscence syndrome and a control group comprising 12 non-superior semi-circular canal dehiscence syndrome patients, all with available magnetic resonance imaging data. The imaging scans were anonymised, and reviewed blindly and independently by three experienced radiologists.

Results

There was low sensitivity and specificity, with average values of 47 per cent (range, 16.7–66.7 per cent) and 69 per cent (range, 66.7–75 per cent) respectively. Cohen's kappa was 0.75, indicating substantial inter-rater reliability.

Conclusion

Given the low accuracy of 1.5T magnetic resonance imaging in identifying the bony defect in superior semi-circular canal dehiscence syndrome, despite its value in inner-ear imaging, computed tomography or equivalent should be used when superior semi-circular canal dehiscence syndrome is suspected.
