The Role of Videonystagmography (VNG) in Diagnosing and Treating Vertigo

Video-Nystagmography (VNG) plays a critical role in diagnosing and managing vertigo-related conditions. Let’s delve into its significance:

1. Diagnostic Tool: VNG provides a non-invasive examination of eye movements, assessing the functional integrity of the vestibular system. It helps identify underlying causes of vertigo, such as Benign Paroxysmal Positional Vertigo (BPPV) or acoustic neuroma.

2. Detecting Vestibular Dysfunction: VNG helps document unilateral or bilateral vestibular loss, confirms BPPV, and detects central lesions that routine physical exams may miss. It aids in preoperative evaluation, especially for conditions like acoustic neuroma.

3. Differentiating Central vs. Peripheral Lesions: VNG distinguishes between central and peripheral vestibular lesions. If peripheral, it further determines whether the vestibular loss is unilateral or bilateral.

In summary, VNG testing protocols guide treatment strategies by analyzing eye movements in response to various stimuli, ensuring effective management of vestibular disorders. 😊
