An evidenced-based diagnostic tool for superior semicircular canal dehiscence syndrome.
Journal of otology
PURPOSE: To construct a symptoms-based prediction tool to assess the likelihood of superior canal dehiscence (SSCD) on high-resolution CT.
MATERIALS AND METHODS: Mathematical modeling was employed to predict radiologic evidence of SSCD at a tertiary neurotology referral center.
RESULTS: A total of 168 patients were included, of which 118 had imaging-confirmed SSCD. On univariate analysis significant predictors of SSCD presence were: sound/pressure-induced vertigo (
CONCLUSIONS: The likelihood of SSCD on CT scan can be determined with a high degree of certainty based on symptoms recorded at presentation. Using the evidenced-based diagnostic tool validated herein, a score ≥6 with any symptom combination justifies ordering a CT scan.
