Intratympanic steroid for residual dizziness after benign paroxysmal positional vertigo: a randomized controlled study.

OBJECTIVE

This study investigates the effectiveness of intratympanic steroid treatment in managing residual dizziness after benign paroxysmal positional vertigo (BPPV) and its impact on quality of life.

METHODS

Fifty-six patients with unilateral posterior canal BPPV without nystagmus after the Epley maneuver were randomized into two groups. Group 1 received intratympanic steroids (two sessions) with the canalith repositioning maneuver, while Group 2 received only the maneuver. Patients were assessed using the Dizziness Handicap Inventory (DHI), Visual Analog Scale (VAS), and residual dizziness evaluation on Day 1 and Day 10.

RESULTS

Baseline assessments showed no significant differences between groups. On Day 10, Group 1 showed significantly greater improvement in residual dizziness (p = 0.036) and Physical DHI scores (p = 0.047), while other DHI and VAS scores remained similar.

CONCLUSION

This study is the first to show that intratympanic steroids significantly reduce residual dizziness, potentially accelerating recovery and improving quality of life in BPPV patients.
