How should I manage a 49‑year‑old woman with a second episode of benign paroxysmal positional vertigo (BPPV) causing spinning dizziness triggered by any head movement, without headache, nausea, vomiting, fever, cough, focal neurological deficits, or visual changes, and a past medical history of tonsillectomy?

Management of Recurrent BPPV

You should perform the Dix-Hallpike maneuver at bedside to confirm the diagnosis, then immediately treat with a canalith repositioning procedure (Epley or Semont maneuver) without obtaining imaging or prescribing vestibular suppressant medications. 1

Diagnostic Approach

The clinical presentation is classic for BPPV: positional spinning vertigo triggered by head movements, brief episodes, no neurological deficits, no hearing loss, and no syncope. 1

Perform Bedside Diagnostic Testing

• Execute the Dix-Hallpike maneuver by bringing the patient from upright to supine with head turned 45° to one side and neck extended 20°, affected ear down 1
• Look for torsional, upbeating nystagmus which confirms posterior canal BPPV (the most common type) 1
• If the Dix-Hallpike shows horizontal or no nystagmus, perform the supine roll test to assess for lateral canal BPPV 1
• Repeat on the opposite side if initial maneuver is negative 1

What NOT to Do

Do not order imaging studies (CT or MRI) in patients meeting diagnostic criteria for BPPV without additional concerning signs like focal neurological deficits, severe headache, or atypical features 1

Do not order vestibular testing in straightforward BPPV cases 1

Treatment Strategy

Immediate Canalith Repositioning

Treat with a canalith repositioning procedure immediately after diagnosis - this has approximately 80% success rate with 1-3 treatments 1

• The Epley maneuver is the most commonly used and strongly recommended 1
• The Semont maneuver is equally effective - choose based on your familiarity and patient mobility 2
• These maneuvers can be performed during the same visit as diagnostic testing 1

Post-Treatment Instructions

Do not recommend postural restrictions after the canalith repositioning procedure - there is strong evidence against this practice 1

Patients should be informed that:

• Symptoms may resolve immediately or take a few hours to days 1
• Mild motion sensitivity and unsteadiness can persist for days to weeks after successful treatment 1
• They can resume normal activities without head position restrictions 1

Medication Management

Do not routinely prescribe vestibular suppressants (antihistamines like meclizine or benzodiazepines) 1, 3

• These medications are ineffective for BPPV treatment 3
• They have side effects including sedation and fall risk 3
• Consider them only for severe acute nausea during the episode, not as ongoing therapy 1

Alternative Management Option

Observation with follow-up is acceptable if the patient prefers to defer treatment, as BPPV can resolve spontaneously within weeks 1

However, warn the patient that:

• Untreated BPPV increases fall risk, particularly concerning in this 49-year-old woman 1
• Symptoms may persist longer without treatment 1
• She should avoid driving and heights until symptoms resolve 1

Follow-Up and Reassessment

Reassess within 1 month to document resolution or persistence of symptoms 1

If symptoms persist:

• Re-examine for unresolved BPPV (may need repeat maneuvers) 1
• Consider multiple canal involvement 2
• Evaluate for underlying vestibular or central nervous system disorders 1
• Consider referral to ENT or vestibular specialist if refractory 1

Common Pitfalls to Avoid

• Don't rely solely on history - the Dix-Hallpike test is essential for diagnosis as many conditions cause positional dizziness 4
• Don't assume treatment failure means wrong diagnosis - BPPV may require 2-3 treatment sessions 1, 2
• Don't forget to check for horizontal canal BPPV if Dix-Hallpike is negative but history is suggestive 1
• Don't discharge without safety counseling about fall prevention during symptomatic periods 1

Patient Education Points

Explain that:

• BPPV is caused by calcium crystals displaced in the inner ear 1
• It's benign and not life-threatening 1
• Recurrence is common (this is her second episode) 1
• The maneuver physically repositions the crystals back to their proper location 1
• She should return if symptoms include hearing loss, persistent vomiting, severe headache, or neurological symptoms - these suggest alternative diagnoses 1
