Benign Paroxysmal Positional Vertigo After Surgical Drilling of the Temporal Bone

Abstract

The incidence of BPPV after surgical drilling of the temporal bone was around 1%, and the horizontal semicircular canal of the contralateral ear was predominantly involved. Head position during surgery (head restriction to contralateral ear down) as well as limitation of head movement due to compressive mastoid bandage after surgery seems to be responsible for such predominance.
