Superior Canal Dehiscence Syndrome (SCDS)

Background

Superior Canal Dehiscence Syndrome (SCDS) occurs when from a small hole in the bone covering the superior semicircular canal in the inner ear. This leads to dizziness, sound-induced vertigo, and an increased sensitivity to internal noises such as heartbeat or eye movements (autophony). It is NOT dangerous, but can be frustrating.

Causes

SCDS is typically a congenital condition that may become symptomatic later in life due to head trauma, migraine or menopause.

Treatment

Mild cases may be managed with symptom adaptation and lifestyle modifications. Treating migraine can also help many reduce symptoms to a tolerable level. Severe cases may require surgical repair to close the dehiscence, but this is rarely needed.
