What Researchers Did
Researchers conducted a prospective, controlled study at a single tertiary hospital to evaluate if adding vitamins A, C, E, and selenium to standard treatment improved outcomes for patients with idiopathic sudden sensorineural hearing loss (ISSNHL).
What They Found
The group receiving vitamins A, C, E, and selenium (ACE+ group, 70 patients) in addition to standard treatment achieved a mean hearing gain of 36.2 dB. In contrast, the group receiving only standard treatment (ACE- group, 56 patients) had a mean hearing gain of 27.1 dB.
What This Means for Canadian Patients
For Canadian patients diagnosed with idiopathic sudden sensorineural hearing loss, these findings suggest that antioxidant vitamin and selenium supplementation might offer an additional benefit to standard treatment regimens. Patients should consult their audiologist or physician to discuss potential adjunctive therapies.
Canadian Relevance
This study was not conducted in Canada and does not have a direct Canadian connection.
Study Limitations
A limitation of this study is that it was conducted at a single center, which may affect the generalizability of its findings to broader populations.
