OBJECTIVE: To describe the clinical and oculographic features in @entity1 with anterior semicircular canal benign paroxysmal positional @entity9468 and to determine the efficacy of a canalith repositioning procedure for its management. STUDY DESIGN: Case series with chart review of @entity1 presenting positional @entity9468 and positional downbeating @entity346 during a 2-year period. SETTING: Outpatients' tertiary referral center for balance disorders. SUBJECTS AND METHODS: Eighteen @entity1 suffering from positional @entity9468 and presenting positional downbeating @entity346 were treated with a maneuver based on a modification of the procedure proposed by Crevits. MEAN OUTCOME MEASURE: disappearance of positional downbeating @entity346 . RESULTS: Positional downbeating @entity346 was elicited unilaterally with the Dix-Hallpike maneuver in 6 cases. In 4 @entity1 , it was triggered by both left and right Dix-Hallpike tests. In 8 @entity1 , the positional @entity346 was elicited by a straight head-hanging maneuver. The positional @entity346 was purely downbeating in 12 @entity1 . In the remaining, a torsional component was detected. After the treatment, only 1 @entity1 showed positional @entity346 at 30 days. CONCLUSION: In anterior canal benign paroxysmal positional @entity9468 , the presence of a positional downbeating @entity346 in response to positional tests is key for diagnosis. In a significant number of @entity1 , the affected side may not be detected because of the inconstant presence of a torsional component. Treatment with a simplified maneuver based on Crevits's technique can be considered an effective method for the treatment of anterior canal @entity9279 , especially when the affected side cannot be detected clearly.
