Canalith Repositioning Procedure (Epley Maneuver)

The anticipated movements of canaliths in the left posterior canal are shown during the Canalith Repositioning Procedure, resulting in deposition of canaliths in the utricle at the macula and at the base of the posterior canal ampulla. The membranous labyrinths have been positioned with a horizontal canals/ Reids plane angle of +22° and a posterior canal /posterior canal angle of 82°.
