Description

Vertigo can be described as a dizzy or spinning sensation. Some individuals perceive self-motion whereas others perceive motion of the environment. Vertigo may be experienced as an illusion of motion, vague dizziness, imbalance, disorientation, transient spinning or a sense of swaying or tilting.

Vertigo is the predominant symptom of vestibular dysfunction and can be caused by conditions including, but not limited to, benign paroxysmal positional vertigo (BPPV), Meniere’s disease and superior semicircular canal dehiscence (SSCD). Acute vertigo will present as an isolated occurrence and has a distinct beginning and end; chronic vertigo is continuous and/or recurring.

Since vertigo is a symptom of a condition, treatment is focused on the specifics of the disease/disorder, relief of symptoms and promotion of recovery.

The treatment varies according to whether the individual is suffering from acute or chronic symptoms.

Evaluation Methods

Methods for the evaluation of chronic vertigo may be generally referred to as vestibular evaluation and include, but may not be limited to:

  • Caloric vestibular test – Each ear is separately irrigated with cold water and warm water, for a total of 4 irrigations, to create nystagmus in the individual. The individual is observed for any difference between the reaction of the right and the left sides. This testing can be performed with or without recording.
  • During this noninvasive test, the individual stands on a platform that records postural adjustments. In conjunction with computer software, these movements are observed, recorded and measured with eyes open, shut or while wearing special goggles for controlled visual stimulation. It is purportedly designed to help quantify the severity of balance problems, diagnose balance disorders, estimate prognosis and plan treatment. CDP has also been proposed for use in balance retraining, reassessment of treatment progress and for use in the treatment of visual, vestibular or somatosensory (proprioceptor) problems. These tests may also be referred to as balance board testing, equilibrium platform testing or visual vertical testing. An example of this device is the SMART EquiTest.
  • Dynamic or head shaking visual acuity test – By having the individual look at an eye chart in the distance wearing their customary distance vision eyeglasses, if applicable, the individual is asked to read the eye chart while their head is shaken continuously over a small range. Then, the individual reads the chart again while their head is immobile. A computerized system may be utilized as well to test for dynamic visual acuity.
  • Electronystagmography (ENG) – With this test, eye movements are recorded and analyzed via small electrodes placed on the skin around the eyes. ENG testing is generally the same as the caloric vestibular test, optokinetic nystagmus test, positional nystagmus test and/or spontaneous nystagmus test; however, in this variation, the results are recorded in addition to being observed.
  • Head impulse or head thrust test – During this test, the individual wears their usual prescription eyeglasses and is instructed to keep their eyes on a distant target, while the head is then turned quickly and unpredictably by the examiner. The normal response is that the eyes remain on the target.
  • Optokinetic nystagmus test – For this exam, a rotating drum made of alternating light and dark vertical stripes is placed in front of the individual and the individual is instructed to stare at the drum without focusing on any one stripe. The eyes are observed for nystagmus while the drum is rotated in one direction. The direction of the drum is reversed. No electrodes are used.
  • Peripheral vestibular, central nervous and corneo-retinal potential involvement test – An automated combination of tests that utilize five electrodes which purportedly allow physicians to test for central nervous system and peripheral vestibular involvement, as well as receive a corneo-retinal potential value in less than 25 minutes. An example of this device is the VAT-ENGplus Combo. (Refer to Coverage Limitations section)
  • Positional nystagmus test (Barany or Dix-Hallpike maneuver) – This testing involves moving the individual rapidly from the sitting to the lying position with the head tilted downward off the table at 45 degrees and rotated 45 degrees to one side to assess whether the eyes can maintain a static position when the head is in a different position.
  • Rotary chair testing – This testing involves sitting in a rotational computerized chair with a seat belt and security head strap. A pair of infrared video goggles are worn to record eye movements in response to movements of the chair. This test is usually an addition to ENG and videonystagmography (VNG) testing.
  • Saccadic testing – A general term used to describe various evaluations for nystagmus.
  • Spontaneous nystagmus test – During this test, the individual's eyes are observed for spontaneous nystagmus as the individual is asked to look straight ahead, 30 degrees to 45 degrees to the right and 30 degrees to 45 degrees to the left. No electrodes are used and no recording made.

The test begins with an individual securely strapped to a special table in a supine (flat) position for approximately 15 minutes. The table is then quickly lifted to an angled position similar to that of standing for approximately 45 minutes. The individual’s heart rate and blood pressure are monitored continuously throughout the test to record changes that would be similar to a syncopal episode. (Refer to Coverage Limitations section)

Vestibular autorotation test (VAT) – During this test, the individual wears a lightweight head strap with five electrodes which monitors head and eye movements. While following a moving target with the eyes, the individual moves the head back and forth or up and down in time with gradually accelerating computer-generated tones. (Refer to Coverage Limitations section)

Vestibular evoked myogenic potential (VEMP) – This testing examines otolith and vestibular nerve function by measuring muscle responses or electrical activity in response to nerve stimulation. Headphones are placed over the ears and small electrodes are attached with an adhesive to the skin over the neck muscles. Repetitive sounds are transmitted through the headphones and the electrodes record the response of the muscle to the vestibular stimuli.

There are two types of VEMP testing that may be utilized during this type of assessment. They may be done independently or together and can be useful in evaluating for superior semicircular canal dehiscence.

  • Cervical VEMP (cVEMP) tests the saccule and inferior nerve response
  • Ocular VEMP (oVEMP) tests the utricle and superior nerve response

Vibration induced nystagmus testing (VIN), skull vibration induced nystagmus testing (SVINT), bone conduction vibration – With this testing, a vibrating tuning fork or a battery-operated vibrating device is placed at various points on the head and neck, usually on the mastoid bone, while eye movements are observed.

Videonystagmography (VNG) – Similar to ENG, however with this evaluation eye movements are recorded by an infrared video camera mounted inside goggles that the individual wears instead of sticky-patch electrodes. The testing is generally the same as the caloric vestibular test, optokinetic nystagmus test,

Treatment Methods for the treatment of chronic vertigo include, but may not be limited to:

  • Intratympanic injection – Medication (usually dexamethasone, gentamicin or methylprednisolone) is delivered directly into the middle ear providing an increased drug concentration to the affected area.

noninvasive techniques are utilized as a treatment for BPPV. Particle repositioning maneuvers include, but are not limited to, the Brandt-Daroff exercises, the Epley maneuver and the Semont maneuver. The theory behind these therapies is that through a series of rotational movements, the particles will be cleared out of the semicircular canals via the common crus of the utricle where they will no longer have an impact on the dynamics of the semicircular canals. All of these maneuvers are generally well tolerated; however, they sometimes cause a migration of debris into the anterior and horizontal canals which cause other variants of positional vertigo.

Transtympanic micropressure – A tympanostomy tube is implanted between the external ear canal and the middle ear. At the time of treatment, an ear cuff is inserted into the external ear canal and a handheld air-pressure generator (connected to a tabletop air-pressure therapy unit) automatically delivers low- frequency, low-amplitude pressure pulses to the middle ear through the tympanostomy tube. One example of a portable device is the Meniett which was developed for the treatment of Meniere’s disease. The device uses positive pressure pulses to the middle ear via the earpiece and ventilation tube to purportedly reduce excess fluid and pressure in the inner ear. Meniett is no longer being manufactured. (Refer to Coverage Limitations section)

Vestibular implant – A unilateral vestibular implant is being investigated as an option to treat vestibular dysfunction. It is comprised of an implanted stimulator, electrode array, and external processor. The stimulator is implanted in the inner ear and delivers electrical pulses to the semicircular canal branches of the vestibular nerve through electrodes. The external processor is comprised of a

The stimulator is implanted in the inner ear and delivers electrical pulses to the semicircular canal branches of the vestibular nerve through electrodes. The external processor is comprised of a head-worn unit and a power and control unit. The head-worn unit is held on the scalp by magnets and senses head motion and delivers power and signals across the scalp to the implanted stimulator. The power and control unit sends information to a computer to allow for device setting adjustments and it also monitors the battery level. The device has not been approved by the US Food & Drug Administration (FDA). (Refer to Coverage Limitations section)

  • Vestibular rehabilitation – This therapeutic program utilizes exercises to help regain the sense of balance. Specific movements of the head and body are developed for individuals with the intent of reducing or eliminating motion provoked or positional sensitivity.
