Diagnostic Approach and Management of Vertigo

Diagnostic Workup

The American Academy of Otolaryngology-Head and Neck Surgery recommends determining if vertigo is triggered by specific head movements to suggest benign paroxysmal positional vertigo (BPPV) 1
The Journal of the American College of Radiology suggests assessing associated symptoms such as hearing loss, tinnitus, neurological symptoms, or headache 2
The American Academy of Otolaryngology-Head and Neck Surgery recommends performing the Dix-Hallpike maneuver to diagnose posterior canal BPPV, observing for characteristic torsional, upbeating nystagmus 1, 3
If Dix-Hallpike is negative but history suggests BPPV, the American Academy of Otolaryngology-Head and Neck Surgery recommends performing the supine roll test to assess for lateral canal BPPV 3

The Journal of the American College of Radiology states that imaging is not recommended for typical BPPV with a positive Dix-Hallpike test 2, 3
The Journal of the American College of Radiology recommends considering MRI brain with contrast when vertigo presents with additional neurological symptoms, atypical nystagmus patterns are observed, or the patient fails to respond to appropriate treatment 2, 4, 5

The American Academy of Otolaryngology-Head and Neck Surgery recommends canalith repositioning procedures (CRP) as the treatment of choice for posterior canal BPPV 1
The American Academy of Otolaryngology-Head and Neck Surgery states that the Epley maneuver has success rates of 90-98% when performed correctly 6
The American Academy of Otolaryngology-Head and Neck Surgery recommends reassessing patients within 1 month after initial treatment to confirm symptom resolution 5, 7

The American Academy of Otolaryngology-Head and Neck Surgery recommends reevaluating patients who fail initial treatment for persistent BPPV, incorrect initial diagnosis, or underlying peripheral vestibular or central nervous system disorders 5, 6
The American Academy of Otolaryngology-Head and Neck Surgery states that treatment failure rates for a single-session repositioning maneuver range from 15-50%, but success rates reach 90-98% with repeated procedures 6

The American Academy of Otolaryngology-Head and Neck Surgery recommends counseling patients about potential recurrence of BPPV and educating them about increased fall risk, especially in elderly patients 7
The American Academy of Otolaryngology-Head and Neck Surgery suggests scheduling follow-up within 1 month after initial treatment and advising patients to report atypical symptoms that may indicate underlying disorders 5, 7
