Benign positional vertigo: recognition and treatment
An editorial error occurred in this Fortnightly Review by Thomas Lempert and colleagues (19 August, pp 489-91). In figure 3 the second and third photographs were rotated. The correct version of the figure is published here.
Canalolithiasis theory of benign positional vertigo. From left to right: Orientation of posterior canal in head upright position with debris shown resting in bottom canal (arrow). When head is moved to dependent position the debris sinks in the canal under the influence of gravity to cause flow of endolymph. Treatment by positional manoeuvres aims at orienting canal so that debris is directed towards canal opening into utricle
