The vestibular system is divided into two parts, namely the otolith organs and semicircular canals. The otolith part has two endorgans (saccule and utricle), while the canal part has three endorgans (lateral, antricor, and posterior semicircular canals). Before the end of the 20th century there were no practical methods to assess these endorgan functions with the exception of lateral semicircular canal function. In the 21st century, two effective methods for assessment of the vestibular labyrinth were developed. Vestibular evoked myogenic potential (VEMP) is a clinical test of the otolith organ while video head-impulse test (vHIT) is a clinical test of the semicircular canal. These tests have the potential to alter the concept of vestibular diseases and the algorithm of diagnostic procedures.
Using vHIT, we can obtain information about the vertical semicircular canals as well as the lateral semicircular canal. Of particular importance is information regarding posterior semicircular canal (PSCC) function because PSCC has a different blood supply and innervation from the lateral and anterior semicircular canals. Assessment of PSCC function could lead to the establishment of some new clinical entities such as inferior vestibular neuritis. As the otolith organ is a sensor of linear acceleration, its disorders seem to result in non-spinning floating vertigo such as tilting or translation sensation. Such symptoms may be caused by isolated otolith disorders.
Through this research topic, we want to encourage investigators and physicians to consider clinical concepts and diagnostic procedures of vestibular diseases. Topic editors welcome any types of manuscripts supported by the journal, comprised of original research article, brief research article, case report, review, mini-review, and meta-analysis - pertaining, but not limited to, the following themes:
• Contribution of VEMP and/or vHIT for establishment of new clinical entity
• How VEMP and vHIT contribute understanding pathophysiology of vestibular diseases
• Clinical application of VEMP an vHIT to vertigo in children
• Change of VEMP and vHIT due to aging
• Endolymphatic hydrops detection using VEMP and vHIT
• VEMP and vHIT in PPPD
