Testing Procedures - Vestibulocochlear Nerve (Vestibular elements)

Vestibular testing can include a variety of special tests. Typical examination includes eye tracking and saccades, static and dynamic balance, head tilting and turning influences on balance, and head-on-body and body-on-head testing. Document normal or abnormal responses.

Vestibulocochlear Nerve Clinical Notes and Interpretation

  • Subjective complaints of vertigo and/or nausea should be recorded and addressed accordingly.
  • Asymmetries may indicate pathology.
  • The most common cause of damage to this nerve is an acoustic neuroma.
  • Because the vestibulocochlear nerve is accompanied by the seventh cranial nerve, symptoms may include dizziness, nausea, and vomiting from the vestibular portion, ipsilateral tinnitus and later deafness from the cochlear portion. A lesion to the seventh cranial nerve may include paralysis of the face, loss of taste, and lack of salivary, mucosal, and lacrimal secretions.
  • Peripheral vestibular injuries, cerebellar injuries, brainstem injuries, and viral meningitis can demonstrate deficits in the above nerve.
