Abstract PDF: Coronavirus disease 2019 (COVID-19) spread rapidly and was declared a pandemic. In this situation, vaccination for COVID-19 is important and has been prompted in many countries. However, a number of adverse events have been reported for the Pfizer, Moderna, and AstraZeneca vaccines. Otolaryngologic adverse events after COVID-19 vaccination were reported, including several cases of sudden sensorineural hearing loss. Vestibular neuritis (VN) is an acute vestibular syndrome that causes acute and spontaneous vertigo due to unilateral vestibular deafferentiation, leading to nausea or vomiting and unsteadiness that can last from days to weeks. Neurotropism for the cochleovestibular nerve, immunoglobulin G mediated immune off-target reaction, and reactivation of latent viruses are hypothesized to be etiologies. Herein, the case of a 49-year-old female who developed VN after COVID-19 vaccination is presented. Although the association between VN and COVID-19 vaccination remains unclear, clinicians should be aware that VN may occur as an adverse event of COVID-19 vaccination.

Dizziness is the most common symptom in elderly patients and has been identified as a risk factor for falls. They can affect objectively the ability to achieve a stable gaze, posture, and gait. Research on the relationship between vestibular hypofunction and falls in elderly people has been rarely performed and the evidence is controversial. Because falls result from various combinations of many factors, validated tools should be used for assessment of falling. Many of the tests and numerous parameters associated with the risk of falling have already been introduced, however guidance on which test is most appropriate for use in a specific setting still lack in the medical community. Therefore, developement of comprehensive fall risk management guideline and assessment tool including physical, psychosocial, environmental factors are necessary to prevent falls in the elderly. Establishment of validity and reliability for relationship among several vestibular function test are more important to evaluate efficiently risk of falls in the dizzy patients. Also we can expect that decreasing risk of fall when conduct the developement of additional customized intervention method using verified assessment tools.
