Surgery ofthe problematic semicircular canal

Inner ear hasthree semicircular canals, and it is the rear canal that is the mostcommon cause of vertigo. Office exam for vertigo includes moving ofthe person being examined in different positions, including lyingdown, and monitoring of a specific form of involuntary, rapid motionof the eye, as it is an indicator of problem in one of the canals,which causes vertigo. Surgery typically lasts for an hour and a half.The inner ear is opened by an incision made behind the ear. Thechannel that causes problems is then sealed off.

There is minimal risk ofinfection or loss of hearing, and results are noticeable within twoweeks after surgery.
