STUDY OF DEMOGRAPHIC FEATURES, CLINICAL CHARACTERISTICS AND RISK FACTORS IN PATIENTS OF BENIGN PAROXYSMAL POSITIONAL VERTIGO (BPPV)

Abstract

Introduction BPPV is the most common peripheral vertiginous disorder in the community.Due to overlapping clinical features, this condition may be misdiagnosed and erroneously treated. Clear understanding of the demographic characteristics and clinical features may help in correct diagnosis and optimal management. Method 100 diagnosed patients of BPPV were prospectively studied. Parameters studied and analysed were:- age group and gender,affected ear and Semi circular canal(SCC), clinical features, various diagnostic and therapeutic manoeuvres, , associated comorbidities, treatment efficacy and recurrence rate. Results BPPV was most commonly seen in 4th decade with a significant female preponderence(M38/F62 ). Posterior-SCC (P-SCC) is most commonly involved(82%) followed by Horizontal-SCC (H-SCC)(17%) and Superior-SCC (S-SCC) (01%). Low serum vitamin-D3 was most commonly associated comorbidity(34%). 84% were primary BPPV while head trauma was the most common secondary cause . Remission rate on repositioning manoeuvre was 73%, recurrence rate 16% and failure rate was 11%. Conclusion Undiagnosed vertigo may significantly impacts the quality of life of a person. BPPV, in spite of being one of the commonest cause of vertigo is often misdiagnosed. If accurately diagnosed, BPPV repositioning manoeuvres have a high cure rate
