Efficacy Positional Vertigo of Particle Repositioning Manoeuvres in Benign Paroxysmal

<bold>Background:</bold>The canalith repositioning procedure (CRP), developed by Epley, was designed to use gravity to treat canalithiasisof the PC. The clinician moves the patient through a series of 4 positions. With each position, the otoconia settle to the lowest part of the canal, move around the arc of the PC, and finally deposit in the vestibule. <bold> </bold>Aim: To determine the efficacy of particle repositioning manoeuvres in benign paroxysmal positional vertigo. <bold> </bold>Study design: Cross Sectional Validation Study <bold> </bold>Settings: Department of ENT, Shaikh Zayed Hospital, Lahore <bold> </bold>Study duration: 20thAugust 2018 to 19th February 2019 <bold> </bold>Methods: A total of 94 patients with benign paroxysmal positional vertigo, 20 to 60 years of age of either gender were included. Patients with cervical spondylosis, ongoing CNS disease (stroke or TIA), and cardiovascular disease and pregnant women were excluded. After this, the Epley manoeuvre (patient was placed in a sitting position with the head turned 45 degrees towards the affected side and then reclined past the supine position) was used to treat the posterior and superior canals, and Lempert manoeuvre (patient lied supine with affected ear down, then quickly turn the head 90 degrees towards the unaffected side, facing up and wait 15-20 seconds between each head turn) was used to treat the horizontal canal. <bold> </bold>Results: Age range in this study was from 20 to 60 years with mean age of 41.78 +/- 9.55 years. Out of 94 patients, 49 (52.13%) were male and 45 (47.87%) were females with male to female ratio 1.1:1. In our study, efficacy of particle repositioning manoeuvres in benign positional paroxysmal vertigo was found in 60 (63.83%) patients. <bold> </bold>Conclusion: This study concluded that efficacy of particle repositioning manoeuvres in benign positional paroxysmal vertigo is quite high.
