ABSTRACT
BACKGROUND AND OBJECTIVES:
This study aimed to analyze the prevalence of superior semicircular canal dehiscence (SSCD) in the coronal images of high-resolution temporal bone computed tomography (TBCT) and to evaluate the diagnostic accuracy of coronal images for SSCD syndrome. SUBJECTS ANDMETHOD:
We retrospectively reviewed high-resolution TBCT scans of 217 patients (434 ears) with SSCD due to various causes. The dehiscence ratio (slices showing dehiscence/total slices showing the superior semicircular canal) in the coronal images of TBCT was calculated, and the optimal cutoff value for the diagnosis of SSCD syndrome was determined using the receiver operating characteristics (ROC) curve.RESULTS:
Of the 434 ears, 64 (14.7%) presented SSCD in more than one slice of the coronal images of TBCT, but only three patients (0.7%) were confirmed with SSCD syndrome. Based on the ROC curve analysis for the dehiscence ratio of 64 ears, the optimal cutoff value for the diagnosis of SSCD syndrome was 0.67 with 100% sensitivity and 90.2% specificity.CONCLUSION:
The majority of cases diagnosed with SSCD syndrome using the coronal images of TBCT were asymptomatic or false-positive. The dehiscence ratio in the coronal images of TBCT combined with a typical symptom can be a highly sensitive and specific diagnostic tool for SSCD syndrome.
