Videonystagmography
(VNG) in Portland, OR
At Inner Ear, we utilize the gold standard in balance diagnostics to help patients overcome dizziness and vertigo. Videonystagmography is a sophisticated testing method that allows our Portland audiologists to evaluate the health of your vestibular system by tracking involuntary eye movements, providing the data necessary for an accurate diagnosis.
The Role of VNG in Balance Disorders
Identifying the root cause of equilibrium issues is the first step toward recovery. Through Videonystagmography, we can determine if your dizziness originates in the inner ear or the brain, allowing us to differentiate between conditions like BPPV, vestibular neuritis, or central nervous system disruptions with clinical precision.
What to Expect During
a VNG Testing
Our Portland audiologists use precision techniques to ensure your safety gear fits perfectly. To create your Custom Hearing Protection, we take a detailed silicone impression of your ear canal, which is then used to manufacture a durable, medical-grade device tailored specifically to your unique anatomy and noise-exposure needs.
Precision Results with Videonystagmography Technology

Hearing Test
Comprehensive hearing assessments include pure-tone and speech testing, tympanometry, and acoustic reflex thresholds to evaluate middle and inner ear function. These results help us determine the type and degree of hearing loss and guide personalized recommendations for your hearing needs.

Hearing Aid Evaluation
If hearing aids are recommended, we take time to discuss your lifestyle, listening goals, and technology preferences. We also perform additional testing, including comfortable and uncomfortable listening levels and speech-in-noise testing, to ensure accurate programming and optimal hearing aid performance. Together, we find the best solution to help you hear clearly and confidently in all settings.

Hearing Aid Fitting & Services
Your hearing aids are expertly programmed and fine-tuned to your individual hearing profile for maximum comfort and clarity.We provide ongoing adjustments, maintenance, and support to ensure you continue to hear your best over time.

Vestibular Evaluations
Dizziness is a complex symptom that can result from dysfunction in several systems, including the inner ear (vestibular system), visual pathways, central nervous system, somatosensory system (which provides feedback from muscles and joints), and gait or postural control mechanisms.

Tinnitus Management
Tinnitus is often a symptom of an underlying condition affecting the ear or auditory system. If you experience ringing or buzzing in your ears, we provide evidence-based tinnitus assessments and personalized management strategies. Our goal is to identify contributing factors, reduce the impact of tinnitus on your daily life, and improve your overall well-being.

Custom Hearing Protection
Protect your hearing without compromising sound quality. We offer custom-fitted earplugs and protection for musicians, swimmers, and individuals exposed to noise, ensuring comfort and effective hearing preservation.

Videonystagmography (VNG)
Is a non-invasive test used to evaluate dizziness, balance concerns, and inner ear function. During the test, you’ll wear lightweight goggles that track your eye movements while you follow moving targets, change head or body positions, and experience gentle temperature changes in the ears. These eye movement responses help us understand how well your balance system is working.
What to Expect:
-
The test is safe and typically takes about 60–90 minutes.
-
You may feel brief dizziness during some portions, which is normal and expected.
-
You can communicate with the audiologist at any time.
-
Most patients are able to return to normal activities shortly after the appointment.

Electrocochleography (ECochG)
Is a non-invasive test used to measure how the inner ear and auditory nerve respond to sound. This test is especially helpful when evaluating conditions such as Ménière’s disease, endolymphatic hydrops, or unexplained dizziness and pressure in the ear.
What to Expect:
-
A small electrode is placed in the ear canal.
-
You will hear a series of clicking or tone sounds.
-
The test is comfortable and usually takes about 30 minutes.
-
There is no dizziness involved and most patients find it easy to tolerate.
