Superior semicircular canal dehiscence causes many symptoms depending on how large the hole in the canal becomes.  The best-known type is vertigo caused by loud sounds.  Normally the sound wave passes harmlessly by the semicircular canals and enters the cochlea, the hearing part of the ear.  However, when there is a hole in the canal,Continue reading “SSCD:  Vertigo from sound and pulsing vertigo  “
