If you experience vertigo when you have a sudden sensorineural hearing loss, you have a lower chance of recovery from the sudden sensorineural hearing loss, according to a Chinese study.
The study consisted of 4,814 patients identified in 10 studies of which 1,709 had sudden sensorineural hearing loss with vertigo and 3,105 had sudden sensorineural hearing loss without vertigo. The recovery rate of hearing was 42.13% for the patients with vertigo and 60.29% for the patients without vertigo. In this way, vertigo was significantly associated with the chance of recovery. Vertigo may therefore be an indicator of a more negative prognosis in the hearing outcome in patients with sudden sensorineural hearing loss, the study states.
About the study
The study was a literature search and meta-analysis of 10 studies published in PubMed, Web of Science and Embase from 1973 to 2017 on the association between the rate of hearing recovery and vertigo. The 10 studies consisted of a total of 4,814 participants.
The study, “Association of Vertigo With Hearing Outcomes in Patients With Sudden Sensorineural Hearing Loss”, was published in JAMA Otolaryngology – Head & Neck Surgery.
