Study of choice
The diagnostic study of choice for BPPV is patient history and observing nystagmus on Dix-Hall pike maneuver.
Investigations:
- Among the patients who present with clinical signs of BPPV, the Dix-Hallpike maneuver is the most specific test for the diagnosis.
Diagnostic results
The following findings are confirmatory for BPPV:
- Recurrent brief vertigo attack which starts with certain head movements.
- Nystagmus on Dix-Hallpike maneuver.
Sequence of Diagnostic Studies
The various investigations must be performed in the following order:
If patients doesn't respond to treatment or doesn't show the typical nystagmus on Dix-Hall pike maneuver, in order to rule out other abnormalities we may perform some additional test such as:
- Electronystagmography (ENG) or video nystagmography (VNG)
- Audiometry
- Neuroimaging
