Video Occulography-Assisted Diagnosis of BPPV and Comparison of Pre- and Post-Intervention Dizziness Handicap Inventory Score
Abstract
Benign paroxysmal positional vertigo (BPPV) is a commonly recognized vestibular disorder which is characterized by brief periods of vertigo and a characteristic nystagmus. The nystagmus is often difficult to appreciate with naked eyes and hence video oculography is a helpful tool. Dizziness Handicap Inventory is an objective way to assess the impact of vertigo on quality of life.
Objective Our study here aims at diagnosing undiagnosed, difficult and missed cases of BPPV using video-oculography and managing it with repositioning manoeuvre. This study also aims at measuring Dizziness Handicap Inventory Scores pre and post repositioning manoeuvre. We also observed the association between Vitamin D levels and the occurrence of BPPV.
Methods and Materials One hundred and twenty-six patients were enrolled in the age group of 18-70 years. After recognizing patients with BPPV, vertigo evaluation was performed. Those patients with suggestive history and suspicion of multiple canal involvement were taken for video-oculography.
Results Forty-four patients were in age group of 50-60 years, having female predominance. 35.71% cases which were missed on clinical examination were correctly diagnosed using video-oculography. The mean pre-intervention DHI was 41.29 ± 15.90 which lowered down to 14.84 ± 11.52 in post-intervention period. The highest DHI scores were seen in multi-canal BPPV involving lateral and posterior semi-circular canals.
Conclusion With the help of vide-oculography we could diagnose more cases of anterior and multi canal BPPV which are often missed. Maximum number of participants had insufficient levels of Vitamin-D and in our opinion correcting it would reduce the occurrence and recurrence rate..
