Summary
Apogeotropic posterior semicircular canal benign paroxysmal positional vertigo (apo-PSC-BPPV) is a rare vestibular disorder. Prompt physical therapy response is key to differentiating it from anterior canal BPPV.
Area of Science:
- Otolaryngology
- Neurology
- Vestibular Science
Background:
- Benign paroxysmal positional vertigo (BPPV) is a common cause of dizziness.
- Apogeotropic posterior semicircular canal BPPV (apo-PSC-BPPV) is a rare variant.
- Anterior semicircular canal BPPV (ASC-BPPV) presents with similar nystagmus.
Observation:
- This case series includes seven patients with apo-PSC-BPPV, three with bilateral involvement.
- Patients were treated at an otoneurology center between February and July 2023.
- Diagnostic oculomotor responses include torsional downbeating positional nystagmus.
Findings:
- Short-term follow-up response to physical therapy is crucial for diagnosis.
- Distinguishing apo-PSC-BPPV from ASC-BPPV relies on treatment response.
- Demographic data, clinical course, and therapy responses were analyzed.
Implications:
- Accurate diagnosis of apo-PSC-BPPV is essential for effective treatment.
- Understanding differential diagnosis aids in managing rare BPPV variants.
- This study highlights the importance of timely physical therapy assessment.
