![]() The Epley maneuver is specifically for posterior canal BPPV and would not help BPPV of the horizontal canal. There are other forms of BPPV where the otoconia enter the horizontal canal, and very rarely the anterior canal. Numerous studies put the success rate for BPPV of the posterior canal in the high 90% range. In fact, success rate is so high that if the treatment fails, it is more likely that the diagnosis is wrong than it is that the repositioning procedure failed to move otoconia out of the posterior canal. First, no treatment works on everybody, but repositioning for BPPV has a very high success rate. Some patients continue to complain of positional vertigo after undergoing treatment with the Epley maneuver. Residual Dizziness: Repositioning Failure? So let’s revisit that and explore some related newer reports, as well as talk about people that do not improve after repositioning for BPPV type of vertigo. A few years ago, I did a post here discussing patients that continued to complain of imbalance and “fleeting disorientation” after successful treatment using the Epley maneuver or some other form of canalith repositioning.
