Vestibular Clinical Assessment

1. Patient History Evaluation

• Symptom Description: Detailed questioning of symptoms such as dizziness, imbalance, vertigo, tinnitus, and hearing loss.
• Symptom Onset and Duration: Examining when symptoms began, their duration, triggers, and severity.
• Medication and Medical History: Evaluating the patient’s current and past medications, chronic illnesses, past infections, or trauma.

2. Fiziksel Muayene:

Evaluation of Eye Movements: Assessing for nystagmus (involuntary eye movements), which may indicate a disorder in the central or peripheral vestibular system.

Head Movement Tests: Observing eye movements during head rotations in various directions. These tests help identify asymmetries in the vestibular system.

Dix-Hallpike Maneuver: A test performed when positional vertigo (e.g., benign paroxysmal positional vertigo – BPPV) is suspected. It involves positioning the patient’s head in a specific way to check for vertigo and nystagmus.

3. Vestibular Tests

VNG (Videonystagmography): Evaluates balance functions of the inner ear and central nervous system by tracking eye movements.

VEMP (Vestibular Evoked Myogenic Potentials): Measures the contraction response of the sternocleidomastoid muscle to sound stimuli, assessing the saccule (a part of the inner ear) and vestibulospinal reflex pathways.

Caloric Test: Evaluates how each ear’s vestibular system functions by applying warm and cold water or air to the inner ear.

Posturography: Measures how well balance is maintained in static and dynamic situations. The patient stands on various surfaces to assess the functioning of the balance system.

4. Hearing Tests

Audiometry: Evaluates hearing levels and detects hearing loss that may be associated with vestibular problems.

Tympanometry: Measures middle ear pressure, assessing the mobility of the tympanic membrane and middle ear function.

5. Imaging Techniques

MRI (Magnetic Resonance Imaging) or CT (Computed Tomography):
Used to examine structures such as the inner ear, brainstem, and cerebellum in detail.

6. Treatment Plan Development

Rehabilitation Programs: Vestibular rehabilitation includes physical therapies and exercises designed to manage balance problems.

Medication Therapy: Medications may be prescribed to alleviate symptoms or treat the underlying cause.

Surgical Intervention: In severe cases, surgical procedures may be required.

Vestibular clinical assessment helps identify the root cause of an individual’s balance issues and enables the determination of appropriate treatment options.
