Lateral canal peripheral positional vertigo diagnosis: a neurophysiological approach

Area of Science:

• Neurology
• Otolaryngology
• Vestibular System

Background:

• Lateral semicircular canal peripheral positional vertigo (LC-PPV) is a frequent cause of vertigo.
• Accurate side determination is essential for effective LC-PPV treatment.
• Current diagnostic methods for LC-PPV lateralization can be challenging.

Purpose of the Study:

• To establish a systematic diagnostic strategy for lateralizing LC-PPV.
• To utilize endolymphatic flow dynamics for improved diagnostic accuracy.
• To validate the efficacy of the Bow and Lean and supine roll tests in LC-PPV diagnosis.

Main Methods:

• Analysis of endolymphatic flow dynamics.
• Application of the Bow and Lean test for positional vertigo assessment.
• Utilizing the supine roll test to evaluate lateralization in LC-PPV.
• Systematic diagnostic approach for LC-PPV.

Main Results:

• The study provides a structured method for diagnosing LC-PPV.
• Endolymphatic flow analysis aids in identifying the affected side.
• The Bow and Lean and supine roll tests are effective in LC-PPV lateralization.

Conclusions:

• A systematic diagnostic approach based on endolymphatic flow dynamics improves LC-PPV lateralization.
• The Bow and Lean and supine roll tests are valuable tools for diagnosing LC-PPV.
• Accurate lateralization is achievable through this systematic diagnostic strategy.
