- Background and Objectives: Although several methods of repositioning maneuver have been introduced for the benign paroxysmal positional vertigo involving horizontal canal (HC-BPPV), no study has investigated the nystagmus pattern during the repositioning maneuver and its correlation with the repositioning results. Therefore, we evaluated the predictive value of the nystagmus for successful repositioning by studying the nystagmus pattern during the position of the Gufoni’s maneuver.
Materials and Methods: Seventeen consecutive patients (age range=36~76 years, median age=64), with a diagnosis of HC-BPPV were recruited between July and August 2010. The Gufoni's maneuver for apogeotropic and geotropic nystagmus was performed. After 30 minutes, the treatment outcome was evaluated according to the nystagmus pattern at the individual stage of Gufoni’s maneuver. Successful treatment was defined by the resolution of positional vertigo in geotropic HC-BPPV and nystagmus shifted from apogeotropic to geotropic in apogeotropic HC-BPPV.
Results: In the successfully treated patients, 4 of 6 patients had the contralesional nystagmus between 1st and 2nd position of Gufoni’s maneuver. Ipsilesional nystagmus in 1st position of Gufoni’s maneuver was observed in 1 patient with apogeotropic nystagmus. And the other 1 patient with Geotropic HC-BPPV showed no nystagmus in 2nd position after contralesional nystagmus in 1st position of Gufoni’s maneuver. Unsuccessfully treated 11 patients had a conversion of nystagmus direction in 2nd position after 1st step.
Conclusion: During the 2nd position of the Gufoni’s maneuver, a nystagmus toward unaffected side predicts a successful repositioning, whereas reversed nystagmus is suggestive of poor response to repositioning.

Abstract
PDF
- Benign paroxysmal positional vertigo (BPPV) originating from the posterior semicircular canal (pSCC) is a common vestibular disorder. Advanced age, head or ear trauma, other inner ear disorders, female sex and osteopenia/osteoporosis are known predisposing factors for pSCC BPPV. An association with simultaneous ipsilateral sudden deafness remains to be elucidated. We report a 62-year old woman with sudden deafness and simultaneous ipsilateral pSCC BPPV.

Abstract

- Periodic alternating nystagmus (PAN) is characterized by horizontal nystagmus that reverses direction periodically. PAN can occur in both congenital and acquired conditions. We report a 58-year old man with peripheral vertigo and hearing impairment showing PAN in darkness.
