What was done
This is a narrative review describing the clinical presentation, diagnostic evaluation, and differential diagnosis of semicircular canal dehiscence (SCD) syndrome, focusing on high-resolution thin-slice computed tomography (CT) and magnetic resonance imaging (MRI).
What was found
The abstract reports no numerical data. It notes that clinical SCD syndrome typically presents with sound- or pressure-induced rotational vertigo with nystagmus, autophony, bone-conducted hyperacusis, and pseudo-conductive hearing loss. It emphasizes that high-resolution thin-slice CT combined with MRI forms the diagnostic cornerstone, but a substantial proportion of individuals with radiologic dehiscence remain asymptomatic, necessitating careful differential diagnosis.
Why it matters
The review outlines the imaging approach for semicircular canal dehiscence and reminds clinicians that radiological dehiscence is often incidental and asymptomatic.
Limits
As a narrative review, the paper provides no original human data, sample size, systematic search strategy, or quantitative metrics of diagnostic accuracy.
