ABSTRACT
Benign paroxysmal positional vertigo [BPPV] is classically described by positioning induced vertigo and nystagmus. In view of the conflicting published results comparing the success of different treatment modalities, the aim of those work was to evaluate the results of the most popular three methods, Epley maneuver with and without using mastoid virbator and the Brandt and Dar off exercises [BDE]. Also, to study the role of the mastoid vibrator in facilitating the diagnosis in cases with a positive history and negative initial Dix-Hallpike test who require repetition of the test on other occasions. Ninety-two patients with acute, untereated unilateral posterior canal benign paroxysmal positional vertigo [PC-BPPV] were recruited. The patients were randomly divided into three groups. The first [31 patients] were tested [Dx-Hallpike] and treated by Epley maneuver without using mastoid oscillator. The second [31patients] were tested and treated by Epley maneuver using the mastoid oscillator. While the third group [30 patients] was instructed to perform the Brandt and Dar off exercise. It was concluded that the Epley maneuver particularly with mastoid oscillation has become the first line treatment for PC-BPPV
