What Researchers Did
Researchers administered hyperbaric oxygen therapy to 19 patients with sudden sensorineural hearing loss who had not responded to initial medical treatment.
What They Found
Hyperbaric oxygen therapy appeared to improve pure tone hearing thresholds, especially at low frequencies, in patients with sudden sensorineural hearing loss unresponsive to medical therapy. Positive outcomes were more likely observed with increased patient age and a shorter delay in receiving the therapy.
What This Means for Canadian Patients
For Canadian patients experiencing sudden sensorineural hearing loss that does not respond to initial medical treatments, hyperbaric oxygen therapy might offer a potential alternative to improve hearing. Early consideration of this therapy, particularly for older patients, could potentially lead to better outcomes.
Canadian Relevance
This study has no direct Canadian connection.
Study Limitations
This preliminary report involved a small sample size of 19 patients and highlights the lack of standardized management and undetermined protocols for hyperbaric oxygen therapy.
