How Common Are Auditory Manifestations in Vestibular Migraine? A Systematic Review and Meta-Analysis
Abstract
Abstract Objective To estimate the prevalence and characterise the clinical significance of auditory manifestations in adults with definite or probable vestibular migraine. Methods PubMed, Scopus and the Cochrane Library were systematically searched. Patient-level prevalence data were pooled using random-effects models with logit-transformed proportions. Hearing loss and hyperacusis were synthesised narratively when quantitative pooling was inappropriate. Results Fifteen studies were included. Twelve studies (n = 1,967) contributed to the aural-fullness meta-analysis and 13 (n = 1,887) to the tinnitus meta-analysis. Pooled prevalence was 28.8% for aural fullness (95% CI, 19.8–40.0%; I² = 95.3%) and 40.7% for tinnitus (95% CI, 30.3–52.0%; I² = 94.7%). Hearing-loss definitions were too heterogeneous for pooling, and evidence for hyperacusis remained limited. Conclusion Aural fullness and tinnitus are common in vestibular migraine, but substantial heterogeneity limits precise prevalence estimation. Standardised auditory assessment is needed to improve phenotyping and differential diagnosis.
