What Researchers Did
Researchers described two patients who developed bilateral hearing loss following viral infections, specifically mumps and varicella-zoster.
What They Found
They found that in both patients, hearing loss on the contralateral side developed a few days after the initial side, with normal vestibular function. Despite treatment with steroids, antiviral agents, and hyperbaric oxygen, the bilateral hearing loss persisted in both patients, requiring hearing aids.
What This Means for Canadian Patients
Canadian patients experiencing sudden bilateral hearing loss, especially after a viral illness, should be aware that it may be permanent despite treatment. This highlights the importance of early diagnosis and management, including potential hearing aid use, for such cases.
Canadian Relevance
This study has no direct Canadian connection.
Study Limitations
A significant limitation of this study is its small sample size, consisting of only two case reports, which limits the generalizability of the findings.
