  • Title: The effects of superior semicircular canal dehiscence on the labyrinth: does size matter?
    Author: Rajan GP, Leaper MR, Goggin L, Atlas MD, Boeddinghaus R, Eikelboom RK.
    Journal: Otol Neurotol; 2008 Oct; 29(7):972-5. PubMed ID: 18665008.
    Abstract:
    BACKGROUND: Superior semicircular canal dehiscence (SSCD) is characterized by lack of bony covering of the superior semicircular canal in the inner ear, resulting in a third mobile window with altered functioning of the superior semicircular canal. Vertigo in association with sound and pressure changes often occurs. This study examines the relationship between dehiscence size and frequency of sound-induced vertigo. METHOD: Retrospective review of 22 patients with SSCD, noting the auditory frequency producing the maximal electronystagmographic response. RESULTS: The study found a correlation between dehiscence size and stimulator frequency of r = 0.856, p < 0.001. The larger the dehiscence, the lower the frequency of stimuli required to provoke a vestibular response. CONCLUSION: The relationship found between the superior canal dehiscence size and the stimulator frequency has clinical implications in the diagnosis and management of patients with SSCD.
