Performa Vestibular Evoked Myogenic Potential dalam Diagnosis Benign Paroxysmal Positional Vertigo

Abstract

Background Benign Paroxysmal Positional Vertigo (BPPV) is the most common peripheral vestibular disorder.Vestibular Evoked Myogenic Potentials (VEMP) is a non-invasive procedure that assesses vestibular function consisting of oVEMP and cVEMP. Based on previous studies, VEMP showed a positive correlation with the Dix-Hallpike test in the diagnose of BPPV. Objective This study aims to assess the performance of VEMP in the diagnose of BPPV. Methods This research is a diagnostic study with a cross-sectional design. The study sample consisted of 22 BPPV patients. The Dix-Hallpike examination was performed in the acute phase of BPPV and then a VEMP examination was performed. Diagnostic performance is assessed based on the Area Under The Receiver-Operator Curve (AUC) on the Receiver Operating Characteristic (ROC) curve. Results Of the 22 subjects, the average age was 41,56±10,78 years and the majority was female (59,1%). The Area Under Curve (AUC) value on the Receiver Operating Characteristic (ROC) curve where in this study the AUC value of oVEMP was 0.864 which have a good performance and cVEMP was 0.545 which have a very weak performance. In the oVEMP diagnostic test, a sensitivity value 90.9% and a specificity 81.8% were obtained, where high sensitivity results can be used as screening. While the cVEMP diagnostic test obtained a sensitivity value 9.1% and a specificity 100% where high specificity results can be used for diagnosis. Conclusion Ocular Vestibular Evoked Myogenic Potentials have good performance in BPPV diagnosis while Cervical Vestibular Evoked Myogenic Potentials have a very weak performance in BPPV diagnosis
