Role of computerized dynamic posturography in evaluating sinugenic vertigo.

Area of Science:

• Otolaryngology
• Neurology
• Vestibular System

Background:

• Vertigo associated with rhinosinusitis (sinugenic vertigo) is infrequently documented.
• The underlying pathophysiologic mechanisms of sinugenic vertigo remain unclear.

Purpose of the Study:

• To investigate sinugenic vertigo using computerized dynamic posturography (CDP).
• To propose a potential pathophysiologic mechanism for vertigo linked to rhinosinusitis.

Main Methods:

• A prospective study involved 16 patients diagnosed with rhinosinusitis.
• All participants underwent CDP shortly after diagnosis.
• Patients with vertigo or abnormal CDP results had follow-up CDP assessments.

Main Results:

• Five patients reported new-onset vertigo.
• CDP indicated a combined disorder in 3 patients despite intact vestibular signs.
• Follow-up CDP showed normal results in these 3 patients once they recovered.

Conclusions:

• A notable 20% prevalence of sinugenic vertigo with abnormal CDP findings was observed.
• These findings suggest the paranasal somatosensory system may be crucial in the pathophysiology of sinugenic vertigo.
