Objectives: The analysis of benign paroxysmal positional vertigo (BPPV) with videonistamography (VNG) is few.
Aim: My aim is to discuss the place of VNG in the accurate diagnosis and treatment of BPPV.
Subjects and Methods: A total of 124 patients diagnosed as BPPV were included in the study (2013-16). Visual images during diagnostic maneuvers were recorded and analyzed by VNG. The European Evaluation of vertigo scale (EEV) was administered before and after the treatment. The R Project for Statistical Computing was used for statistical analyses.
Results: The posterior canals (PC) were involved in 59.7%, the lateral canals (LC) in 26.6% and the anterior canals (AC) in 13.7%. 18.5% were cupulolithiasis, 72.6% were canalolithiasis. Among the canalolithiasis patients; 64.9% of PCs, 77.8% of the LCs, 93.3% of the ACs were rehabilitated with 1 maneuver, 35% of the PCs, 22.2% of the LCs, 6.7% of the ACs more than 1. Among the cupulolithiasis patients; 100% of the PCs, 81.8% of the LCs, 100% of the ACs were rehabilitated with 1 maneuver, 18.2% of the LCs more than 1 maneuver. The p values of EEV before and after treatment for PCs, LCs and ACs and in total were found meaningful as 2/(10^43) (<0.05), 1.006 / (10^22) (< 0.05) , 1.597/(10^12) (<0.05) and 2.756/(10^75) (< 0.05) .
Conclusion: With VNG we can easily differentiate the nystagmus and the positions of the debris in the exact canal and side. This gives accurate diagnosis and therapy with high success rate.
