In all cases, our approach begins with an initial assessment and history taking, prompting into the reported symptoms. Depending on the initial findings, further investigations may be necessary which involve electrophysiological tests, radiological imaging and blood tests to rule out any serious underlying conditions. Following the comprehensive diagnostic process, the identified causes and associated symptoms will then be appropriately managed with a combination of medical, surgical and rehabilitative interventions.
Medical management could involve pharmacological treatment to alleviate symptoms or address the root cause. Surgical intervention might be considered in cases where structural abnormalities are detected. Rehabilitative strategies such as vestibular rehabilitation will help patients restore their balance function and improve their quality of life, leading a normal lifestyle.
Giddiness & Balance Assessments
As part of our comprehensive hearing health services, we perform a range of giddiness and balance assessment tests in a specialised facility within our centre. Our advanced vestibular diagnostic tests help identify the underlying causes of the balance disorders and facilitate more effective treatments.
1. Videonystagmography (VNG)
VNG is a common test used to evaluate issues related to balance and dizziness. It involves a series of assessments where eye movements are recorded with an infrared camera while the patient lies in different positions. By analysing these eye movements during these tests, abnormalities in the vestibular system contributing to your symptoms can be identified. VNG is particularly effective in diagnosing vestibular disorders such as benign paroxysmal positional vertigo (BPPV), vestibular neuritis and labyrinthitis.
2. Video Head Impulse Test (vHIT)
vHIT is an advanced diagnostic tool used to assess the function of the semicircular canals, which play a crucial role in maintaining balance during head movements. During this test, a lightweight, high-speed camera records eye movements while the patient performs quick and small head movements. This test helps to assess the function of the vestibulo-ocular reflex (VOR), which stabilizes vision during head movements. vHIT is particularly useful for diagnosing vestibular hypofunction and other disorders affecting the semicircular canals.
3. Electrocochleography (ECoG)
ECoG is a specialized test used to measure the electrical potentials generated in the inner ear elicited by sound stimulation. This test can be useful for diagnosing Meniere’s disease, a disorder characterized by episodes of vertigo, hearing loss, tinnitus, and a feeling of fullness in the ear. During the ECoG test, electrodes are placed near the ear to measure the electrical activity generated by the cochlea and auditory nerve, aiding in determining the cause of your symptoms.
4. Vestibular Evoked Myogenic Potential (VEMP)
VEMP is a test used to evaluate one portion of the balance organ known as the saccules. It is part of the otolith organs in the vestibular system responsible for detecting vertical movements. During the VEMP test, electrodes are placed on the neck muscles, and sound stimuli are presented to elicit a muscle response. This response is measured to evaluate the integrity of the saccule and the related neural pathways. VEMP testing is valuable for diagnosing conditions such as superior canal dehiscence syndrome (SCDS).
