Superior Semicircular Canal Dehiscence: a Potential Cause of Vestibular and Auditory Impairment Following Head Trauma

This article is aimed at reviewing the pathophysiology, assessment methods, etiologies, treatment options, and correlation with head trauma for this unique entity.Recent FindingsCommon SSCD symptoms include chronic disequilibrium, abnormal eye movements, and auditory disturbances. The pathologic opening into the bony labyrinth by SSCD can lead to irregular fluid flow and pressure gradients, disrupting inner ear function. Most patients with incidentally discovered SSCD on imaging are asymptomatic; a secondary injury event is believed to trigger onset of symptoms via acute intravestibular and/or intracranial pressure changes. Multiple treatment options exist for SSCD, ranging from conservative measures to invasive surgeries.SummaryAbnormal vestibular and auditory functions are common symptoms of SSCD, which may be precipitated by head trauma. SSCD management should match the severity of symptoms to maximize benefits while minimizing morbidity.
