What Researchers Did
Researchers retrospectively reviewed 50 cases of sudden deafness to assess the effect of adding hyperbaric oxygen therapy to conventional treatment and the influence of patient age.
What They Found
Patients receiving hyperbaric oxygen therapy in addition to conventional treatment showed a mean hearing gain of 37.9 dB, significantly higher than the 20.0 dB gain in those receiving conventional treatment alone (P < 0.05). This benefit was more pronounced in patients younger than 50 years, who experienced a mean gain of 51.4 dB, compared to 23.3 dB in those older than 50 years (P 0.05).
