37 patients suffering from tinnitus (age 18-86 years) were treated in three ways: 1. Rehabilitation: mobilisation, physical training, physiotherapy. 2. Same as 1 but with placebo laser added. 3. Same as 1 but with functional laser added. Laser used was 830 nm 300 mW. 2-3 treatments per week were given, total 10 treatments. Treatment protocol: 90 J/cm2 CW on mastoideus, 45 J/cm2 5 Hz on mastoideus, 50 J/cm2 CW on acoustic duct, 25 J/cm2 5 Hz on acoustic duct. Tebokan Egb 761 ginko medication was added to treatment. Results were classified as no effect/less than 50% relief/more than 50% relief/no more tinnitus. The percent wise outcome for the three groups was: 1.29.4/44.1/17.6/8.9 2. 25.8/48.4/25.8/0 3. 19.4/19.4/35.5/25.8 Auris Nasus Larynx. 1997; 24 (1): 39-42.

In an extended study over 3 years Prochazka [1263] evaluated the effect of laser in a group of 200 patients. These patients were taking gingko biloba preparations (73%) or Betahistadine (39%) and also had physical therapy, mainly directed at the neck vertebrae. Laser therapy was performed with a 300 mW GaAlAs laser, 75 J/cm2 into the ear and 135 J/cm2 behind the ear. The outcome was: no more tinnitus 26%, more than 50% relief 43%, less than 50% relief 15%, no effect 16%. In addition a group of 31 patients were selected for a double blind study where the same therapy as above was performed, but one group received placebo laser. At 6 months the outcome was as follows, with laser/no laser: no more tinnitus 25.8%/0.0%, more than 50% relief 35.5%/25.8%, less than 50% relief 19.4%/48.4%, no effect 19.4%/25.8%.
