Although many studies are available concerning the treatment of sudden deaf
ness using hyperbaric oxygenation, only a few of these deal with tinnitus.
The aim of the present study was to evaluate the therapeutic use of hyperba
ric oxygenation in cases of tinnitus. A total of 193 patients, having under
gone primary intravenous hemorheologic therapy, were treated with hyperbari
c oxygenation. Tinnitus was evaluated before, after ten sessions and after
15 sessions using a tinnitus questionaire. Additionally, an audiometric exa
mination was performed. Measurable improvements of the tinnitus occurred in
22% of the patients, whereas a moderate improvement was seen in 17% of cas
es. 10.4% showed an excellent improvement and tinnitus disappeared complete
ly in two patients. The improvement rate decreased in those cases where the
time from onset of tinnitus exceeded 40 days. In conclusion, hyperbaric ox
ygenation seems to be a moderately effective additional treatment in the th
erapy of tinnitus after primary hemorheologic therapy, provided the time fr
om onset of tinnitus is less than 1 month.
