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..
