According to a study, researchers examine the association of vertigo with a prognosis of hearing variables in SSHL. Vertigo may be a risk factor for sudden sensorineural hearing loss; future studies are needed to examine whether treatment of vertigo might contribute to the recovery of hearing. For patients with the sudden sensorineural hearing loss (SSHL), vertigo may be negatively associated with recovery of hearing. The study was published online in JAMA Otolaryngology-Head & Neck Surgery.
They examined the correlation of vertigo with a prognosis of hearing variables in SSHL using data from 10 studies. A total of 4,814 unique patients were identified; 1,709 had SSHL with vertigo and 3,105 had SSHL without vertigo.
Sensorineural Hearing Loss
Sudden sensorineural hearing loss (SSHL) accompanied by vertigo may portend a negative prognosis in the hearing outcome.
The researchers found that for each study selected, the Newcastle-Ottawa Scale (range of 0 to 9) score was greater than 7. The recovery rate of the hearing was 42.13 and 60.29 percent in the group with vertigo versus the group without vertigo. There was a significant correlation for vertigo with a worse hearing recovery (odds ratio, 2.22; 95 percent confidence interval, 1.54 to 3.2).
In subgroup analyses of the grading system using the Siegel criteria and systemic corticosteroid therapy, similar results were obtained. Within the subgroup receiving intratympanic corticosteroids, there was no significant correlation of vertigo with the prognosis of SSHL (odds ratio, 1.78; 95 percent confidence interval, 0.64 to 4.94).
Recovery Of SSHL
Current evidence revealed that vertigo may be negatively associated with hearing recovery in patients with SSHL, except in a subgroup that received intratympanic corticosteroids. Corticosteroid injection may be more effective for treatment of SSHL accompanied by vertigo; future studies are needed to determine whether treatment of vertigo might contribute to the recovery of SSHL.
