Key Points
· A total of 4290 patients with sudden sensorineural hearing loss from
23 studies were included in this meta-analysis.Vertigo may be a negative
factor in sudden sensorineural hearing loss. Vertigo was significantly
associated with poorer hearing recovery (OR = 2.13)
· the combined treatment regimen has better efficacy in patients with
sudden sensorineural hearing loss with vertigo. The association was
attenuated in the subgroup treated with hyperbaric oxygen chamber
therapy(OR= 1.76) and intracameral steroid injections(OR= 1.62).
·More original literature is required to clearly evaluate the patient’s
age, underlying disease, and initial level of hearing loss in order to
quantify the specificity of the sudden sensorineural hearing loss
population. Furthermore, it elucidates the impact of vertigo on the
prognosis of sudden sensorineural hearing loss.·
