Elegibilidade das manobras de reposicionamento de partículas no tratamento da vertigem posicional paroxística benigna do canal semicircular lateral: revisão sistemática

Abstract

Introduction: LC-BPPV is a labyrinthine condition that, despite being benign, impairs the patient's quality of life. It is an incapacitating condition both socially and professionally. An adequate approach allows the precise identification of the problem and a clear direction for the resolution, not only of the symptoms, but also of the cause. There are therapeutic options capable of controlling the symptoms; therefore, repositioning maneuvers stand out as being resolutive and with extremely low risks for the patient. Objective: investigate which maneuvers have been most elected among researchers to treat patients diagnosed with LC-BPPV, caused by canalolithiasis or cupulolithiasis. Method: Systematic literature review using the combined descriptors in Portuguese and English, “vertigem posicional paroxística benigna”, “vertigem”, “canais semicirculares”, “reabilitação”, "benign paroxysmal positional vertigo", "vertigo", "rehabilitation", "therapeutics", "semicircular canals", "lateral semicircular canal" in the databases Biblioteca Virtual em Saúde (BVS), United States National Library of Medicine (PubMED). Results: Eight studies were selected for the review. It was observed that Gufoni's maneuver was elected in six studies, being used to treat both canalolithiasis and cupulolithiasis, geotropic and apogeotropic. Conclusion: The most elected repositioning maneuver for the management of benign paroxysmal positional vertigo of the lateral semicircular canal is Gufoni's maneuver, followed by Barbecue's maneuver.
