Revision as of 02:53, 3 January 2023

There was no difference in the outcome from the treatment of tinnitus with two different hyperbaric oxygen regimens.

Clinical Bottom Line:

1. No difference in outcome between the two HBOT groups

Citation/s:1.Porubsky, C., Stiegler, P., Matzi, V., Lipp, C., Kontaxis, A., Klemen, H., Smolle-Jüttner, F. Hyperbaric oxygen in tinnitus: Influence of psychological factors on treatment results? ORL : Journal for Oto - Rhino - Laryngology and its Related Specialties,2007; 69(2):107-12.

Lead author's name and fax:Christian Porubsky: christian.porubsky@klinikum-graz.at

Three-part Clinical Question:For patients with tinnitus, does HBOT at 2.2 ATA for 60 mins daily for 15 days compared to a 2.5 ATA treatment on the same schedule result in any greater resolution of symptoms?
Search Terms: tinnitus, hearing loss, retraining

The Study:Non-blinded randomised controlled trial with intention-to-treat.
The Study Patients: Patients presenting for the treatment of tinnitus (time from onset from < 2 wks to > 1 year).
Control group (N = 180; 180 analysed): 100% oxygen breathing at 2.2 ATA for 60 minutes daily for 15 working days.
Experimental group (N = 180; 180 analysed): As above but at 2.5 ATA.

Comments:
1. The authors were primarily interested in the effect of pre-treatment expectations on resolution of symptoms and the RCT aspect was a relatively minor aim.
2. I have assumed '2.2 bar' here was in fact 2.2 ATA.
3. Pre-treatment expectations influenced the chance of improvement (positive expectation 60.3% improved; negative expectation 19% improved. P < 0.05).
4. Time to HBOT did not have any statistically significant influence on outcome.
5. On non-random analysis the authors concluded HBOT was not better than placebo treatment results.
