With further research on the relationship between gut microbiota and human health, discussions on various gut-X axis have been increasingly prevalent. Evidence indicates that microbiota dysbiosis is closely linked to the onset and progression of audiovestibular disorders and the gut-ear axis has gradually been recognized as a vital systemic regulatory pathway. This article systematically reviewed the interaction mechanisms between microbiota dysbiosis and audiovestibular diseases, intervention strategies, research limitations and future perspectives. This axis functions mainly through immune-mediated barrier damage, metabolic disorder and neurotransmitter crosstalk. Modulation of the gut microbiota can alleviate symptoms of certain audiovestibular disorders. This review aims to provide novel insights for the pathogenesis, intervention and clinical management of audiovestibular disorders.
