HBOT for ear problems

Here are some numbers from a big study done in Germany.
I thought that was very interesting for the poor victims of tinnitus:

"Accordingly, most of the studies show that HBOT is most effective in reducing hearing loss and tinnitus in the first three months following hearing loss or acoustic trauma. Regarding hearing loss alone, an overview of clinical studies from Germany shows HBOT is effective in 50% of cases in reducing hearing loss by 20 dB or more. Approximately 11% have a full recovery.

Regarding tinnitus, evaluations of 7766 patients in the same overview showed reduction of the intensity of tinnitus by 50% in approximately 70% of the cases treated within 3 months. Approximately 30% of patients had their tinnitus completely resolved. Tinnitus with duration of more than 3 months showed a 50% improvement in the intensity of tinnitus in 30% of patients. After 12 months of chronic tinnitus, no improvement was seen." 1
