What Researchers Did
Researchers reported a case of sudden sensorineural hearing loss in a patient one day after receiving hyaluronic acid filler injections into the nasolabial folds.
What They Found
The patient's audiogram revealed moderately severe sensorineural hearing loss, while an MRI showed no abnormalities. Despite receiving transtympanic steroid injections and hyperbaric oxygen therapy, the hearing loss persisted at the time of writing.
What This Means for Canadian Patients
Canadian patients considering hyaluronic acid fillers should be informed about the potential, albeit rare, risk of sudden sensorineural hearing loss. Clinicians should maintain vigilance for this serious adverse event, especially given its persistence despite treatment.
Canadian Relevance
This study has no direct Canadian connection.
Study Limitations
A major limitation is that this is a single case report, preventing the establishment of a causal relationship between the filler and hearing loss.
