What Researchers Did
Researchers conducted an evidence-based literature review using Medline to propose a treatment algorithm for sudden sensorineural hearing loss (SSNHL).
What They Found
They found that all patients with SSNHL should undergo a thorough history, examination, and pure tone audiogram, with MRI recommended for all cases of idiopathic SSNHL. For idiopathic SSNHL, oral steroids may be offered, and intratympanic steroids can be considered as primary or salvage therapy if systemic steroids are contraindicated or ineffective, while routine antiviral therapy is not supported by evidence.
What This Means for Canadian Patients
Canadian patients experiencing sudden sensorineural hearing loss should expect a comprehensive evaluation including an audiogram and potentially an MRI to identify the cause. Treatment options for idiopathic cases may involve oral or intratympanic steroids, aligning with evidence-based approaches for this otological emergency.
Canadian Relevance
This study has no direct Canadian connection as it was not conducted in Canada, nor does it involve Canadian researchers or patients.
Study Limitations
As a literature review, this study's findings are dependent on the quality and scope of the existing evidence, and it does not present new primary data.
